FURNAS SIEMENS

Furnas Siemens represents the integration of two established industrial control lineages: Furnas, a Brazilian manufacturer of motor controls and switchgear founded in 1941, and Siemens, the German multinational with a century-long history in electrical engineering and automation. The Furnas brand, acquired by Siemens in 2000, continues to produce a range of electromechanical components under the Siemens umbrella, with products designed for global industrial applications. The product families available through 3G Electric focus on HVACR controls, switches, and thermostats, including auxiliary switches, contactors, and switching relays. These components are built to meet international standards for electrical performance and durability, with specifications such as rated operational currents, voltage ranges, and mechanical endurance that are critical for plant engineers and maintenance managers. For example, the auxiliary switch (3RH1921-1CA10) is a modular device used in control circuits for signaling and interlocking, while the contactor (3RT2027-1AK60) is designed for switching motors and other loads in industrial environments, with a rated operational current typically up to 40 A at 400 V AC. The switching relay (3TX7114-5LC13) provides reliable switching for auxiliary circuits in control panels. These components are commonly applied in HVACR systems, pump controls, conveyor systems, and other industrial machinery where reliable switching and control are required. 3G Electric supplies these Furnas Siemens products globally, offering multiple SKUs with logistics support to ensure availability for maintenance, repair, and operations (MRO) needs. The product range covers replacement parts for existing installations, making it suitable for procurement specialists seeking direct substitutes for legacy Furnas or Siemens components. Technical buyers should note that these products are typically rated for IP20 enclosures, require proper mounting and wiring per manufacturer guidelines, and are compatible with standard DIN rail or panel mounting systems. The specifications provided for each SKU include manufacturer part numbers, which facilitate cross-referencing with existing equipment. 3G Electric does not modify or customize these products; they are supplied as manufactured by Siemens under the Furnas brand. For engineers and managers, the key considerations are the electrical ratings, environmental conditions (temperature range, humidity), and compliance with local codes, which are documented in the product datasheets available from Siemens. The Furnas Siemens line is a practical choice for maintaining operational continuity in facilities that use these components, with the advantage of global sourcing through 3G Electric's distribution network.

Frequently asked questions

Common questions about FURNAS SIEMENS from 3G Electric.

What is the difference between a Furnas Siemens contactor and a switching relay?

A contactor, such as the 3RT2027-1AK60, is designed for switching power loads like motors, heaters, and lighting, with higher current ratings and arc suppression. A switching relay, like the 3TX7114-5LC13, is used for auxiliary control circuits, typically with lower current ratings and for signaling or interlocking purposes. Contactors are built for frequent switching under load, while relays are for logic and control functions.

Are Furnas Siemens auxiliary switches compatible with Siemens SIRIUS contactors?

Yes, the Furnas Siemens auxiliary switch (3RH1921-1CA10) is part of the Siemens SIRIUS modular system and is designed to mount directly onto SIRIUS contactors and other devices. It provides additional contact blocks for signaling or control functions. Compatibility is ensured by the common mounting interface and electrical ratings specified in the product documentation.

What are the typical voltage and current ratings for Furnas Siemens contactors?

The contactor 3RT2027-1AK60 is rated for operational currents up to 40 A at 400 V AC for AC-3 duty (motor switching). For AC-1 duty (resistive loads), the rating may be higher. Coil voltages vary by variant; this model typically uses a 24 V DC or 230 V AC coil. Always verify the specific part number for exact ratings, as variations exist within the product family.

Can Furnas Siemens switching relays be used in HVACR control panels?

Yes, the switching relay 3TX7114-5LC13 is suitable for HVACR applications, such as controlling fans, compressors, or dampers. It is designed for auxiliary circuits in control panels, with a rated operational current typically up to 10 A at 250 V AC. Ensure the relay's coil voltage matches the control system and that the enclosure provides adequate protection (e.g., IP20 for indoor panels).

How do I identify the correct Furnas Siemens replacement part for my existing equipment?

Use the manufacturer part number (e.g., 3RH1921-1CA10) printed on the existing component. Cross-reference with the product type (auxiliary switch, contactor, relay) and electrical specifications (voltage, current, coil type). 3G Electric lists these part numbers for each SKU, allowing direct substitution. If the part number is illegible, consult the equipment manual or contact Siemens support for identification.
