Altivar 312; ATV312
All models, all serial numbers
The documentation that comes with the resistor does not indicate.
Braking resistors VW3A7723 to VW3A7725 do not have thermal protection temperature switches. Braking resistors VW3A7701 to VW3A7705 has thermal protection temperature switches. The tripping temperature is 120 deg. C. Max voltage - current AC = 250V ~ 1 A DC = 24V ~ 0.1 A
