Schneider Electric Braking Resistor 100W 60 Ohm

Description

The Schneider Electric VW3A7702 is a robust braking resistor designed for use with the Altivar series of frequency inverters and servo drives. It effectively dissipates excess energy generated during motor deceleration, preventing overvoltage faults on the drive's DC bus and enabling rapid, controlled stops. This component is crucial for applications involving high inertia loads or frequent start-stop cycles.

FAQ

Braking resistors can get very hot during operation. The VW3A7702 is designed for use in ambient temperatures up to 50 deg C without derating. It is critical to ensure proper ventilation and clearance around the unit to allow for adequate heat dissipation.

Yes, this is possible to meet different application requirements. Connecting two resistors in series will double the resistance to 120 Ohms. Connecting them in parallel will halve the resistance to 30 Ohms and double the power dissipation capacity to 200W. Always consult the drive's technical manual for minimum resistance values and correct configuration.

While specifically designed for the Schneider Altivar and Lexium series, this resistor can generally be used with any Variable Frequency Drive (VFD) that requires an external braking resistor with matching specifications (60 Ohm, 100W). Always verify that the VFD's braking chopper specifications are compatible.
