Why Choose the ABB OTP36A6M 45A 6-Pole Safety Switch?
The ABB OTP36A6M (1SCA022401R2620) is a robust 45 A, 6-pole enclosed safety switch-disconnector designed for manual switching and electrical isolation in industrial machinery, motor installations and low-voltage distribution systems. Part of the ABB OTP plastic enclosed switch range, it combines six main switching poles, a durable protective enclosure and a highly visible red and yellow operating handle.
With a 45 A AC-23A operational current rating at 380–415 V AC and a corresponding 22 kW motor switching rating, the OTP36A6M is suitable for appropriately rated industrial motor and inductive-load applications. Its six-pole construction provides additional switching flexibility compared with conventional three-pole isolators, allowing multiple conductors to be disconnected together through a single operating mechanism.
The OTP36A6M features a grey IP65 plastic enclosure, an IK08 impact resistance rating and a padlockable red and yellow pistol-grip handle. It is supplied with one normally open auxiliary contact, a fixed neutral terminal, protective earth terminals and top and bottom cable-entry knockouts. These features make it a practical enclosed switching solution for machine builders, electrical contractors, panel manufacturers and industrial maintenance engineers.

Six-Pole Electrical Isolation for Industrial Machinery and Motor Circuits
The ABB OTP36A6M is designed to provide dependable manual switching and isolation where an installation requires more than the three main switching poles found on conventional three-phase isolators. Its six-pole construction enables multiple conductors to be switched together using one operating mechanism, making it suitable for appropriately engineered multi-conductor isolation arrangements.
For industrial motor applications, the OTP36A6M provides a 45 A AC-23A operational current rating at 380–415 V AC, corresponding to a 22 kW motor switching rating. AC-23A is a utilisation category associated with switching motor loads and other highly inductive loads. The correct device rating must always be selected according to the operating voltage, connected load and applicable switching duty.
The red and yellow pistol-grip handle provides a clearly visible manual control point on the front of the enclosure. Its padlocking capability supports maintenance isolation and lockout arrangements, while the interlocked cover helps restrict normal access to the internal switching equipment when the handle is in the ON position. The cover interlock can be defeated for authorised access where permitted by the manufacturer's instructions and relevant safety procedures.
The OTP36A6M is housed in a grey plastic enclosure rated IP65, offering protection against dust and water jets when correctly installed. The IK08 impact resistance rating provides additional durability for industrial settings. Knockout openings at the top and bottom allow cable entries to be configured for the installation, with suitable cable glands required to maintain the intended enclosure protection.
For control and indication purposes, the unit includes one normally open auxiliary contact. This can be used with a compatible electrical control or monitoring circuit, for example to provide switch-position signalling. The assembly also incorporates a fixed neutral terminal and protective earth terminals, although the neutral terminal is not an additional switched pole.
The OTP36A6M is a manual switch-disconnector, not an automatic circuit breaker or motor overload relay. It does not independently provide automatic overload or short-circuit tripping. The complete installation must include appropriately selected circuit protection, conductor sizing and safe isolation procedures.
