Why Choose the ABB OT800E03N3P 800 A 3P+N Switch-Disconnector?
The ABB OT800E03N3P is a heavy-duty 800 A 3P+N switch-disconnector designed for dependable manual switching and electrical isolation in industrial low-voltage power distribution systems. Identified by ABB order code 1SCA022779R4780, it forms part of ABB's high-performance OT switch-disconnector range.
This configuration combines three switched poles with a detachable neutral link integrated into the operating mechanism. The neutral pole is positioned on the left side, making the OT800E03N3P particularly suitable for three-phase systems where the neutral conductor also requires coordinated isolation.
The OT800E03N3P is front operated and base mounted and is supplied with a black ON-OFF handle and shaft. It delivers an 800 A AC-23A rating at 400–415 V AC, an operational power rating of 450 kW at 400–415 V AC, and a rated operational voltage of up to 1000 V AC.

High-Current Three-Phase and Neutral Isolation
A 3P+N switch-disconnector provides coordinated isolation for a three-phase supply together with its neutral conductor. The OT800E03N3P incorporates a detachable neutral link into the switching mechanism, providing a purpose-designed arrangement for installations where neutral isolation forms part of the electrical distribution strategy.
With an 800 A rating, high AC-23A switching capability and a 20 kA one-second withstand rating, the ABB OT800E03N3P is engineered for substantial industrial distribution duties. Its included handle and shaft, base-mounted construction and high operational voltage capability support integration into large switchboards and power distribution assemblies.
Typical Applications
- Industrial main switchboards.
- Three-phase and neutral electrical isolation.
- High-current power distribution systems.
- Industrial machinery and process equipment.
- Main and sub-main distribution assemblies.
- Commercial and industrial electrical infrastructure.
