  • Description

Rated 40 A at 4 poles, the ABB 1SCA151253R1001 OTM40F4C21D400C is a self-supplied automatic transfer switch for 380-415 V AC mains-generator installations. Its type 21D control module offers adjustable operating parameters, so switching delays and voltage thresholds can be tuned to the site rather than left at a factory default. It withstands 2.5 kA for 1 s and mounts on a DIN rail.

Selection Notes

The 21D controller gives the 1SCA151253R1001 field-adjustable switching delay and voltage thresholds at the 40 A, 4-pole end of ABB's Compact ATS range, useful where a small generator needs a longer stabilization delay before the load transfers. Against the fixed-parameter 20D unit in the same frame, the trade-off is a few grams of extra weight (2.11 kg vs 2 kg) for configurable settings; where standard timing is already acceptable, the 20D version needs no on-site configuration at all.
