- Description
The ABB OT2000E04P (SKU 1SCA108038R1001) is a 2000 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 for front-operated base mounting with a 1000 V insulation voltage (Ui).

Selection Notes
The OT2000E04P's 176 kA Icm is more than three times the 55 kA Icw figure, reflecting that making capacity and short-time withstand are measured differently — Icm is the peak the switch can close onto, Icw the RMS current it can carry for 1 second. Specify this switch-disconnector, not the change-over OT2000E0_CP models, where a single 2000 A feed only needs isolating.
