Product details

Trip class & current setting

The 3RB3113-4RB0: The trip class is user-selectable to 5E, 10E, 20E, or 30E — covering everything from short-acceleration conveyors to longer-starting compressors. The current setting follows the logic: IMotor must be above the lower setting value and below 3.5× the upper setting value, so you can dial in the motor FLA without adding a current transformer.

This relay is designed for contactor mounting — it clips onto a compatible S00 contactor, no extra DIN rail footprint. Screw terminals accept 1× (0.5 to 4 mm²) solid or 2× (0.5 to 2.5 mm²) stranded. Fastening uses a Pozidriv PZ2 driver. Depth comes to 73 mm, width 45 mm, height 79 mm. Mount in any position; shock rated 15g / 11 ms.
