ABB 1SCA112710R1001 OTM2500E3CM230C 3P 55 kA Icw Motorized Changeover Switch

Built for 2500 A at 3 poles, the ABB 1SCA112710R1001 OTM2500E3CM230C motorized changeover switch moves heavy loads between two power sources using a 220-240 V AC motor operator. It carries a 55 kA short-time withstand for 1 s and a 1000 V insulation rating. A direct-mount handle gives manual override, and the switch is base mounted for panel installation.

Selection Notes

The 1SCA112710R1001 carries the same frame footprint (645 x 377 mm) as the 2000 A, 3-pole unit but a higher 2500 A thermal rating and 85 W power loss per pole, so enclosure ventilation sized for the 2000 A model should be rechecked before substituting this one. Short-time withstand stays at 55 kA for 1 s, matching the 2000 A frame, so the step up in current rating does not buy extra fault-current headroom. Line-only 3-pole switching suits installations that bond neutral on both sides; the 4-pole 2500 A version is the alternative where neutral must be isolated.
