- Description
The ABB OT2500E04P (SKU 1SCA105140R1001) is a 2500 A, 4-pole switch-disconnector for a 1000 V main circuit, certified to IEC 60947-3. It withstands a 55 kA fault current for 1 second (Icw), makes against 176 kA (Icm), and uses 100 mm wide lug terminals on a front-operated, base-mounted frame.

Selection Notes
The OT2500E04P shares its 55 kA Icw and 176 kA Icm with the 2000 A switch-disconnector in the same frame family, so stepping up to 2500 A does not change the fault-current duty the switch can handle — only the conventional thermal current and power loss increase. Specify it for isolating a single 2500 A feed rather than transferring between two sources.
