OT800E03P ABB 800 A 3-Pole Switch-Disconnector

Why Choose the ABB OT800E03P 800 A 3-Pole Switch-Disconnector?

The ABB OT800E03P is a heavy-duty 800 A three-pole switch-disconnector / isolator switch designed for dependable manual switching and electrical isolation in demanding industrial low-voltage power distribution systems. Identified by ABB order code 1SCA022718R9410, it forms part of ABB's established OT high-performance switch-disconnector range.

The OT800E03P is a front-operated, base-mounted unit with the operating mechanism positioned at the left-hand end of the switch. It is supplied with a black IP65 operating handle and shaft plus the required terminal bolt kit, providing a practical package for integration into industrial switchboards and distribution assemblies.

Rated at 800 A, the OT800E03P provides 800 A AC-21A, AC-22A and AC-23A performance at 380–415 V AC. It supports a main-circuit operational voltage of up to 1000 V AC, with 20 kA short-time withstand current for 1 s and an AC-23A operational power rating of 450 kW at 400–415 V AC.

High-Current Three-Phase Electrical Isolation

A three-pole switch-disconnector provides simultaneous manual switching and isolation of all three phase conductors in a three-phase electrical system. This creates a defined isolation point for machinery, distribution equipment and downstream circuits during maintenance, servicing and controlled shutdown procedures.

The ABB OT800E03P combines 800 A three-pole switching with high AC-23A performance, a 20 kA one-second withstand rating and a compact base-mounted design. With its operating handle, shaft and terminal bolt kit included, it provides a practical high-current isolation package for substantial industrial switchboards and power distribution assemblies.

Typical Applications

• Industrial main switchboards.
• High-current three-phase circuit isolation.
• Main and sub-main power distribution systems.
• Industrial machinery and production equipment.
• Manufacturing and process installations.
• Commercial and industrial electrical infrastructure.
