OT1600E22P ABB 1600 A 4-Pole Isolator Switch

Why Choose the ABB 1SCA022871R6090 OT1600E22P Isolator Switch?

The ABB 1SCA022871R6090, order code OT1600E22P, is a heavy-duty 1600 A, 4-pole switch-disconnector / isolator switch designed for dependable high-current switching and electrical isolation in industrial power distribution systems. As part of the ABB 311027-OT Switches product group, it belongs to ABB's high-performance OT range for switchboards, distribution assemblies and demanding industrial installations.

The OT1600E22P is a front-operated, base-mounted 4-pole switch-disconnector with its operating mechanism positioned between the poles. It is supplied complete with a black ON-OFF plastic pistol-grip handle, adjustable operating shaft and terminal bolt kit, providing the principal operating components required for integration into an industrial switchboard or enclosure.

With a conventional free-air thermal current of 1600 A, the OT1600E22P provides 1600 A AC-22A and 1250 A AC-23A at 400–415 V. It also supports operational voltages up to 1000 V, delivers 710 kW AC-23 operational power at 400 V and has a 50 kA rated short-time withstand current.

Four-Pole High-Current Industrial Isolation

Switch-disconnectors provide a dedicated means of manually switching and isolating electrical circuits from their power source. The ABB OT1600E22P combines a substantial 1600 A thermal current rating with four-pole simultaneous switching, making it suitable for industrial power distribution systems where four conductors need to be positively switched and isolated together.

The OT1600E22P is supplied as a practical operating package with the OHB274J12 black pistol-grip handle, OXP12X280 adjustable shaft and M12 × 60 mm terminal bolt kit. The handle is IP65 protected and padlockable in the OFF position, while the switch's 50 kA short-time withstand capability and high AC-22A and AC-23A ratings support demanding industrial isolation duties.

Typical Applications

• High-current industrial power distribution.
• Main and sub-main electrical isolation.
• Four-pole switchboard isolation.
• Industrial switchboards and distribution assemblies.
• Large machinery and production equipment.
• High-power motor and industrial load switching.
