Why Choose the ABB OTP36T6M 6-Pole 22kW IP65 Enclosed Safety Switch?
The ABB OTP36T6M is a robust six-pole plastic enclosed safety switch-disconnector designed for reliable electrical isolation of industrial machinery, motors and equipment. Part of the ABB OTP enclosed switch range, it combines a heavy-duty switching mechanism with a durable IP65 enclosure, making it suitable for demanding indoor and outdoor electrical installations.
Rated for 22 kW motor loads at 400–415 V AC under utilisation category AC-23A, the OTP36T6M provides dependable manual isolation for industrial electrical systems. Its six-pole configuration enables simultaneous switching of six conductors, making it particularly useful in applications requiring more switching poles than conventional three-pole isolators.
The switch features a black padlockable pistol handle, an interlocked enclosure cover and metric threaded cable-entry knockouts. Its UV-protected, glass-fibre-reinforced polycarbonate housing provides IP65 protection against dust and water jets. Supplied with a normally open auxiliary contact and fixed neutral and protective earth terminals, the OTP36T6M offers a practical, ready-to-install isolation solution for industrial control and power distribution systems.

Reliable Six-Pole Electrical Isolation for Industrial Machinery
The ABB OTP36T6M is designed for installations requiring dependable disconnection of multiple electrical conductors. Unlike conventional three-pole isolators, its six-pole switching arrangement allows six circuits or conductors to be switched together using a single operating mechanism, provided the installation is designed within the switch's electrical ratings.
This configuration can be useful in machinery and electrical systems with multiple power conductors, coordinated switching requirements or specialised isolation arrangements. The switch is intended for isolation and load switching rather than automatic control, reversing or electrical fault protection.
For motor applications, the OTP36T6M provides an AC-23A rating of 22 kW at 400–415 V AC. The corresponding operational current is 45 A. ABB also specifies an 80 A conventional enclosed thermal current, which represents a different rating and should not be substituted for the AC-23A motor-switching current.
The switch incorporates a black pistol handle that can accommodate up to three padlocks, helping maintenance personnel secure the isolator against unintended operation. Its interlocked cover helps restrict access while the switch is energised, while the defeatable interlock permits authorised access when required by approved maintenance procedures.
IP65 Protection and Practical Cable Installation
The OTP36T6M uses a glass-fibre-reinforced polycarbonate enclosure with UV protection, providing a durable housing for industrial environments. Its IP65 rating indicates dust-tight construction and protection against water jets when the enclosure and cable entries are correctly installed and sealed.
The enclosure provides metric threaded cable-entry knockouts at the top and bottom, with 2 × M32 + M16 openings per side. These allow power and control cables to be routed into the enclosure using appropriately selected cable glands. Compression glands must be ordered separately where required.
A factory-mounted normally open auxiliary contact is provided for suitable control or status-indication applications. Fixed neutral and protective earth terminals support practical wiring arrangements, while the main terminals accommodate conductors from 1.5–35 mm².
With dimensions of 200 × 145 × 90 mm, the OTP36T6M provides a compact enclosed isolation solution suitable for mounting close to machinery, motors and electrical equipment.
