For detailed specifications and availability, contact 3G Electric with your required part number.

How do I identify the correct FURNAS replacement coil for my contactor or relay?

To identify the correct FURNAS replacement coil, refer to the original coil's manufacturer part number, such as 75D73070A. This number is typically printed on the coil or in the equipment manual. The coil must match the contactor or relay model and the control voltage of your system. If the part number is not visible, consult the equipment documentation or provide the contactor/relay model to 3G Electric for cross-reference. Using the correct coil ensures proper electrical compatibility and reliable switching performance in HVACR applications.

What are the typical applications for FURNAS switching relays like the 3RB3026-1QB0?

FURNAS switching relays, such as the 3RB3026-1QB0, are used in HVACR systems to control electrical loads including compressors, fans, and pumps. They provide on/off switching in commercial and industrial heating, ventilation, air conditioning, and refrigeration equipment. These relays are suitable for applications requiring reliable control of motors and other inductive loads. They are often found in control panels, rooftop units, and refrigeration racks. When replacing a switching relay, ensure the coil voltage, contact ratings, and mounting configuration match the original to maintain system integrity.

Does 3G Electric provide technical specifications for FURNAS products?

3G Electric provides available technical specifications for FURNAS products, such as product type and manufacturer part number. For detailed electrical ratings, dimensions, and operating parameters, refer to the original manufacturer's datasheet or contact 3G Electric with the specific part number. While 3G Electric aims to supply accurate information, final verification of compatibility and specifications should be performed by the user. This ensures the component meets the requirements of the intended application.

Can FURNAS controls be used in both new installations and as replacements?

FURNAS controls are primarily used as replacement components in existing HVACR systems, but they can also be used in new installations where the specifications match. The product line includes coils, relays, and thermostats that are designed to meet common electrical and mechanical standards. When used as replacements, they help restore functionality without requiring system modifications. For new installations, verify that the control's ratings and physical dimensions are suitable for the intended equipment. 3G Electric supplies these components for both scenarios, subject to availability.
