  • Description

The ABB 1SCA151255R1001 (OTM63F4C21D400C) is a self-supplied, motor-operated automatic transfer switch rated 63 A at 4 poles, built for 1-0-2 open-transition switching between two power sources. Its 21D controller handles the transfer logic on board, and the unit withstands 2.5 kA for 1 s (Icw) during a downstream fault, before the upstream protection device needs to clear it.

Selection Notes

The 21D controller on this 63 A unit is self-supplied, so it needs no external control transformer or UPS to run the automatic transfer logic. Icw of 2.5 kA for 1 s sets how long the switch can carry a downstream fault before the upstream breaker must clear it - size the upstream protection trip time accordingly. Choose the base or DIN-rail mounting to fit panel depth constraints rather than relying on a fixed mounting plate.
