OT800ES04K ABB 800 A 4-Pole Side-Operated Switch-Disconnector

Why Choose the ABB OT800ES04K 800 A 4-Pole Side-Operated Switch-Disconnector?

The ABB OT800ES04K is a heavy-duty 800 A four-pole side-operated switch-disconnector designed for dependable manual switching and electrical isolation in demanding industrial low-voltage power distribution systems. Identified by ABB order code 1SCA022860R2910, it forms part of ABB's established OT high-performance switch-disconnector range.

Designed for side operation with the mechanism on the left, the OT800ES04K is base mounted for integration into industrial switchboards and distribution assemblies. The K-version includes a black ON-OFF direct-mounted pistol-type handle as standard, with the handle padlockable in the OFF position for controlled isolation.

The OT800ES04K provides 800 A AC-21A, AC-22A and AC-23A switching capability at 380–415 V AC, with an AC-23A operational power rating of 450 kW at 400–415 V AC. Its 1000 V AC rated operational voltage, 20 kA short-time withstand current for 1 s and four-pole configuration make it suitable for substantial industrial distribution duties.

High-Current Four-Pole Side-Operated Isolation

A four-pole switch-disconnector provides simultaneous manual switching and isolation of four conductors, making it suitable for systems where an additional conductor must be disconnected together with the three phase conductors. Side operation can simplify integration where the physical arrangement of a switchboard makes conventional front-operated switching less suitable.

The ABB OT800ES04K combines 800 A four-pole switching with a left-side mechanism and an included direct-mounted handle. Its high AC-23A performance, 20 kA one-second withstand rating and padlockable OFF position provide a robust isolation solution for demanding industrial switchboards and distribution systems.

Typical Applications

• Industrial main switchboards.
• High-current four-pole circuit isolation.
• Three-phase distribution systems requiring four-conductor switching.
• Industrial machinery and production equipment.
• Main and sub-main distribution assemblies.
• Switchboards requiring left-side manual operation.
