SURGE TRAP

SURGE TRAP is a line of surge protective devices (SPDs) designed for external mounting on electrical enclosures and panels. The product family centers on chase-nipple external-mount configurations, which allow the SPD to be installed directly through a knockout and secured with a chase nipple, minimizing wiring and simplifying retrofit or new construction. The devices are available in single-phase and three-phase versions, covering common North American voltage systems including 120V, 240V, 120/208V Wye, 277/480V Wye, 347/600V Wye, 240V Delta, and 480V Delta. Enclosures are polycarbonate and rated NEMA 4X, providing protection against corrosion, dust, and water ingress for indoor and outdoor applications. Key specifications include maximum continuous operating voltages (MCOV) that exceed nominal system voltages, voltage protection ratings (VPR) as low as 1200V for some single-phase models, and maximum surge current per mode up to 50kA. The line includes models with nominal discharge currents of 20A, suitable for branch-circuit and panel-level protection. 3G Electric supplies the SURGE TRAP line as part of its industrial-equipment catalog, offering multiple SKUs with datasheets and logistics support. The product range addresses the need for point-of-use surge protection in commercial, industrial, and institutional facilities, where sensitive electronics and control systems require mitigation of transient overvoltages. Typical applications include HVAC equipment, pumps, motor controls, and distribution panels. The chase-nipple mounting style is particularly relevant for retrofit projects where adding a conventional SPD enclosure would require significant modification. 3G Electric provides global sourcing and delivery for SURGE TRAP devices, with technical documentation available to support specification and procurement. The catalog includes single-phase and three-phase units across the common voltage and configuration spectrum, allowing engineers to match the SPD to the system grounding and voltage characteristics. For technical buyers, the key selection criteria are system voltage, configuration (Wye or Delta), MCOV, VPR, and surge current rating. The SURGE TRAP line provides these parameters in a consistent format, with polycarbonate NEMA 4X enclosures that are suitable for a range of environments. 3G Electric maintains inventory and can source specific SKUs as needed, supporting maintenance, repair, and operations (MRO) as well as capital projects. The brand's focus on external-mount SPDs with chase-nipple connection aligns with common North American electrical practices, where panel-mounted SPDs are often required for service entrance and downstream protection. The product family includes models for both single-phase and three-phase systems, with voltage ratings that cover 120V through 600V AC. This breadth allows specifiers to use a consistent product line across different equipment and panels within a facility. 3G Electric's role is to provide access to these devices with accurate specifications and reliable delivery, without adding unnecessary complexity. The company serves plant engineers, maintenance managers, and procurement specialists who require verifiable technical data and straightforward sourcing. For SURGE TRAP, 3G Electric offers multiple SKUs, datasheets, and logistics support, enabling customers to obtain the correct SPD for their application. The product line's emphasis on external mounting and chase-nipple connection simplifies installation and reduces downtime during replacement or upgrade.

Frequently asked questions

Common questions about SURGE TRAP from 3G Electric.

What voltage systems are covered by SURGE TRAP chase-nipple external-mount SPDs?

SURGE TRAP chase-nipple external-mount SPDs are available for single-phase and three-phase systems. Single-phase models include 120V, 240V, and 120/240V AC. Three-phase models cover 120/208V Wye, 277/480V Wye, 347/600V Wye, 240V Delta, and 480V Delta. Each model specifies a maximum continuous operating voltage (MCOV) that exceeds the nominal system voltage, such as 150V AC for a 120V system or 320/640V AC for a 277/480V Wye system. This range allows selection based on the system configuration and voltage. The chase-nipple mounting is consistent across the line, enabling external installation on enclosures.

What is the maximum surge current rating for SURGE TRAP three-phase SPDs?

Many SURGE TRAP three-phase chase-nipple external-mount SPDs are rated for a maximum surge current of 50kA per mode. This rating applies to models such as the 277/480V AC Wye (SKU 55KN68), 240V AC Delta (SKU 55KN65), and 480V AC Delta (SKU 55KN67). The 50kA per mode specification indicates the device's capacity to divert transient surge currents without damage. For specific models, the voltage protection rating (VPR) varies: for example, the 480V Delta model has a VPR of 3000V (L-L), while the 240V Delta model has 2000V (L-L). These ratings help in coordinating protection with equipment withstand levels.

Are SURGE TRAP SPDs suitable for outdoor installations?

SURGE TRAP chase-nipple external-mount SPDs use polycarbonate enclosures rated NEMA 4X. This rating indicates protection against windblown dust and rain, splashing water, and hose-directed water, as well as corrosion resistance. NEMA 4X enclosures are suitable for indoor and outdoor applications where the device may be exposed to moisture or corrosive environments. However, the installation should follow the manufacturer's instructions regarding mounting orientation and sealing of the chase nipple to maintain the enclosure rating. The polycarbonate material provides durability and resistance to UV degradation, making these SPDs appropriate for many outdoor industrial and commercial settings.

What is the difference between SURGE TRAP single-phase and three-phase models?

SURGE TRAP single-phase models are designed for 120V, 240V, or 120/240V AC systems and protect line-to-neutral and line-to-ground modes. Three-phase models are configured for Wye or Delta systems and protect all phase-to-ground and phase-to-phase modes. For example, a single-phase 240V model (SKU 55KN64) has a voltage protection rating of 1800V (H-G), while a three-phase 240V Delta model (SKU 55KN65) has ratings of 1200V (L-G) and 2000V (L-L). The choice depends on the electrical system configuration and the equipment being protected. Both types use the same chase-nipple external-mount design and polycarbonate NEMA 4X enclosure.

What is the nominal discharge current for SURGE TRAP SPDs?

The nominal discharge current (In) for SURGE TRAP SPDs varies by model. For instance, the single-phase 240V AC model (SKU 55KN64, MPN STXR240P05N) has a nominal discharge current of 20A. This parameter indicates the peak current the SPD can handle for 20 consecutive surges without degradation. It is a key specification for selecting an SPD that matches the expected surge environment. Other models in the line may have different In ratings; consult the individual datasheet for the specific SKU. The 20A rating is typical for branch-circuit and panel-level protection in commercial and industrial applications.

How does the chase-nipple mounting simplify installation of SURGE TRAP SPDs?

The chase-nipple mounting on SURGE TRAP SPDs allows the device to be installed through a standard knockout in an electrical enclosure. The SPD is secured with a chase nipple, which also provides a raceway for conductors. This eliminates the need for a separate mounting bracket or additional enclosure, reducing installation time and material costs. It is particularly useful for retrofit projects where adding a conventional SPD would require significant modification. The external-mount design keeps the SPD outside the panel, saving internal space and allowing easy visual inspection. The polycarbonate NEMA 4X enclosure ensures environmental protection when mounted outdoors or in harsh locations.
