TELEMECANIQUE VW3A58737

Telemecanique Braking Resistor VW3A58737

Description

The Telemecanique VW3A58737 is a high-capacity braking resistor designed for use with variable speed drives, particularly the Schneider Electric Altivar series. It effectively dissipates excess energy generated during motor deceleration, preventing overvoltage faults on the drive’s DC bus and ensuring smooth, controlled stops. Its rugged, ventilated metal enclosure provides reliable thermal performance in demanding industrial environments.

Specifications

• Nominal Power: 1200 W
• Available Power: 600 W
• Resistance: 14 Ohm
• Enclosure Type: Ventilated, IP20

Label Info

• Brand: Telemecanique
• Model: VW3A58737

Application

This braking resistor is primarily used in applications involving high inertia loads, such as conveyors, centrifuges, and lifting equipment, where rapid deceleration is required. It is compatible with Altivar 61 and Altivar 71 series frequency inverters.

Country of Origin

Made in France.

CO2 Impact

By purchasing this reused component, you are contributing to a circular economy and have helped avoid approximately 90.0 kg of CO2 emissions associated with the production of a new unit. This saving is comparable to driving a car for 450 kilometers.

FAQ

What is the IP rating of the VW3A58737 and what does it mean for installation?

The VW3A58737 has an IP20 rating. This means it is protected against solid objects larger than 12.5mm (like fingers) but has no protection against water. It must be installed in a clean, dry environment, typically within a larger control cabinet, to protect it from dust and moisture.

Can I use this resistor with a drive other than a Schneider Electric Altivar?

While designed for Altivar drives, it can potentially be used with other brands of VFDs provided the drive’s specifications for braking resistor ohms and wattage are met. It is crucial to verify that the 14 Ohm resistance value and power rating are compatible with the third-party drive’s requirements to avoid damage.

How does the “Nominal Power” (1200 W) relate to the “Available Power” (600 W) listed on the label?

Nominal power (1200 W) typically refers to the maximum power the resistor can dissipate for short periods (the braking cycle), while available or continuous power (600 W) is the power it can dissipate constantly without overheating. The selection depends on the duty cycle of the braking operation in your application.
