How many amperes does a thermal relay protector draw
The relays, as protected are suitable for use on a circuit capable of delivering not more than 5000 rms symmetrical amperes. Other than the normal tightening of all wire and heater connections, no maintenance should be attempted on the unit. The Size 1 and 2 OLR's have a maximum current rating of 26. In compliance with interna-tional and national standards, the setting current is the rated current of the motor and not the tripping current (no tripping at 1. 05 x. Overload relays protect motors and equipment from thermal damage caused by prolonged overcurrent conditions. Check the motor's nameplate for the FLC. No nameplate? Use this formula: Example: A 5 kW motor running on 220V with 90% efficiency and a 0. Oversetting (Too High): If the.
