EATON IEC

Eaton is a power management company that manufactures electrical components for industrial, commercial, and residential applications. The Eaton IEC product line referenced here centers on DIN rail-mounted circuit protection devices, specifically the FAZ series of miniature circuit breakers (MCBs) and supplementary protectors. These products are designed to meet International Electrotechnical Commission (IEC) standards, which are widely used in industrial control panels, machinery, and equipment globally. The FAZ series includes models with D-curve trip characteristics, which are intended for circuits with high inrush currents, such as those with motors or transformers. The devices are available in various current ratings, from 1 A to 63 A, and in configurations with 2 poles. They are UL489 listed for branch circuit protection or UL1077 recognized for supplementary protection, depending on the model. Voltage ratings include 277/480 V AC and 48/96 V DC, with interrupting capacities ranging from 5 kA to 15 kA at 415 V AC or 10 kA to 14 kA at 277/480 V AC. Terminations are either lug or screw clamp, and all units mount on standard 35 mm DIN rail. 3G Electric supplies the Eaton IEC line as part of its global distribution of industrial electrical equipment. The product range includes multiple SKUs covering different current ratings and protection types, allowing specifiers to select devices that match their overcurrent protection needs. 3G Electric provides access to datasheets, technical specifications, and logistics support for these products, serving plant engineers, maintenance managers, and procurement specialists who require reliable circuit protection components for control panels, HVAC equipment, and industrial machinery. The Eaton FAZ series is part of Eaton's broader portfolio of circuit protection products, which includes molded case circuit breakers, residual current devices, and surge protective devices. The FAZ series specifically addresses the need for compact, DIN rail-mounted protection in space-constrained panels. The D-curve trip characteristic means the breaker will trip at 10 to 20 times its rated current, making it suitable for loads with high starting currents. The 2-pole configuration provides protection for two phases or a phase and neutral, and the devices are available with either lug terminals for ring or fork connectors or screw clamp terminals for direct wire insertion. The UL489 listing indicates the device is suitable for branch circuit protection, while UL1077 recognition means it is intended as supplementary protection, typically downstream of a branch circuit breaker. This distinction is important for code compliance and application suitability. 3G Electric maintains inventory of these Eaton IEC products and can supply them to customers worldwide, with support for documentation and order fulfillment. The company's focus is on providing technical buyers with straightforward access to the specified components, without unnecessary marketing claims. The Eaton FAZ series is one of many product lines that 3G Electric distributes, and it is supported by the company's logistics and customer service infrastructure. For engineers and procurement professionals, the key considerations when selecting these devices include the required current rating, voltage, interrupting capacity, trip curve, and terminal type. The Eaton IEC line offers a range of options to meet these requirements, and 3G Electric can provide the necessary product data to facilitate selection and purchasing.

Frequently asked questions

Common questions about EATON IEC from 3G Electric.

What is the difference between Eaton FAZ UL489 miniature circuit breakers and UL1077 supplementary protectors?

Eaton FAZ UL489 miniature circuit breakers are listed for branch circuit protection, meaning they can be used as the primary overcurrent protection for a circuit. UL1077 supplementary protectors are recognized components intended to provide additional protection downstream of a branch circuit breaker, such as for specific equipment or control circuits. The UL489 devices typically have higher interrupting capacities and are subject to more stringent testing. In the Eaton FAZ series, models with the '-NA' suffix are UL489 listed, while those without are UL1077 recognized. Both types are DIN rail-mounted and available in D-curve, 2-pole configurations.

What does the D-curve trip characteristic mean on Eaton FAZ circuit breakers?

The D-curve trip characteristic on Eaton FAZ circuit breakers means the instantaneous trip threshold is set between 10 and 20 times the rated current. This makes them suitable for circuits with high inrush currents, such as those with motors, transformers, or power supplies. The thermal-magnetic trip mechanism provides overload protection with a delayed response and short-circuit protection with an instantaneous response. D-curve breakers are less sensitive to brief current spikes than B-curve or C-curve devices, reducing the likelihood of nuisance tripping. They are commonly used in industrial control panels and machinery where inductive loads are present.

What are the voltage and interrupting capacity ratings for Eaton FAZ-D63/2 supplementary protectors?

The Eaton FAZ-D63/2 is a 2-pole, D-curve supplementary protector rated 63 A. It supports 277/480 V AC and 96 V DC. The breaking capacity is 5 kA at 415 V AC. It has lug terminals and is UL1077 recognized for supplementary protection. The device mounts on standard 35 mm DIN rail. This model is part of the FAZ series and is suitable for overcurrent protection in industrial control panels and equipment where a higher current rating is required. For specific application questions, consult the datasheet or a qualified engineer.

Can Eaton FAZ series circuit breakers be used in DC applications?

Yes, many Eaton FAZ series circuit breakers and supplementary protectors are rated for DC applications. For example, the FAZ-D1/2-NA, FAZ-D13/2-NA, FAZ-D15/2-NA, FAZ-D30/2-NA, and FAZ-D32/2-NA are rated for 48/96 V DC. The FAZ-D63/2 supplementary protector is rated for 96 V DC. The DC voltage rating is typically lower than the AC rating, and the interrupting capacity may differ. When using these devices in DC circuits, verify the specific DC ratings from the product datasheet. DC applications include control circuits, battery systems, and renewable energy equipment.

What terminal types are available on Eaton FAZ series DIN rail circuit breakers?

Eaton FAZ series circuit breakers and supplementary protectors are available with two terminal types: lug terminals and screw clamp terminals. Lug terminals accept ring or fork connectors and are often used in applications where secure, vibration-resistant connections are needed. Screw clamp terminals allow direct insertion of stripped wire and are common in general industrial wiring. The terminal type is indicated in the product specifications. For example, the FAZ-D63/2 has lug terminals, while the FAZ-D1/2-NA has screw clamp terminals. Both types are designed for use with standard tools and are suitable for DIN rail-mounted installations.
