The ABB OT400E12P is a heavy-duty 400 A three-pole switch-disconnector designed for reliable load switching and electrical isolation in industrial low-voltage power systems. Part of the ABB OT switch-disconnector range, it provides simultaneous three-phase disconnection for switchboards, machinery and power-distribution applications.
The OT400E12P features a front-operated mechanism positioned between the poles, identified by ABB's mechanism arrangement 12. Its base-mounted construction uses lug terminals and is supplied with a black ON-OFF pistol handle and adjustable operating shaft, providing the principal operating components required for enclosure integration.
Rated at 400 A, the OT400E12P provides 400 A AC-21A, AC-22A and AC-23A operational current up to 690 V AC. It has a 1000 V rated operational and insulation voltage, 12 kV impulse withstand voltage and 15 kA for 1 s short-time withstand current for demanding industrial switching duties.
Switch-disconnectors provide a defined means of manually switching electrical loads and establishing circuit isolation for operation, servicing and maintenance. The three-pole ABB OT400E12P enables all three phase conductors to be switched simultaneously, while its mechanism-between-poles arrangement provides a centred operating configuration for industrial switchboard installations.
The OT400E12P combines a 400 A current rating, three-pole construction and mechanism arrangement 12 with strong AC-23A performance. Its 15 kA for 1 s short-time withstand capability, 1000 V operational voltage and supplied handle-and-shaft assembly make it suitable for demanding industrial power-distribution and machinery-isolation applications.
