1SCA022371R3040 ABB 6-Pole 37 kW IP65 Plastic Enclosed Switch-Disconnector

Why Choose the ABB OTP75T6B Plastic Enclosed Switch?

The ABB OTP75T6B is a six-pole plastic enclosed switch-disconnector designed for local isolation and switching of electrical loads and motors. Part of the ABB OTP Plastic Enclosed Switches range, it combines ABB's OT switching technology with a robust enclosure for industrial and commercial electrical installations.

Designed for motor loads up to 37 kW at 400 V AC, the OTP75T6B provides an 80 A AC-23 rating at 400 V and a 100 A AC-21 rating at 400 V. Its enclosure provides IP65 protection, helping protect the switching equipment against dust and water jets when correctly installed.

The OTP75T6B features a six-pole configuration and an I-flange cable-entry arrangement at the top and bottom of the enclosure. A black operating handle, 1NO auxiliary contact, PE terminals and an N-terminal are included, providing a practical enclosed isolation solution for machinery and electrical distribution equipment.

Key Advantages

IP65 Six-Pole Switching for Motor and Load Isolation

The ABB OTP75T6B combines a six-pole switching mechanism and local operating handle within a complete IP65 plastic enclosure. Its 37 kW AC-23A motor rating at 400 V makes it suitable for local isolation of machinery, motors and other electrical equipment where multiple conductors need to be disconnected together.

The enclosure incorporates I-flange cable outlets at both the top and bottom, with the required flanges selected separately to suit the installation. The included 1NO auxiliary contact can be used within compatible signalling or control circuits, while the supplied N-terminal and PE terminals support practical installation within the enclosure.

Typical Applications

• Local isolation of industrial motors up to 37 kW at 400 V.
• Six-pole machinery and equipment isolation.
• Industrial production and process equipment.
• Motor, pump, fan and ventilation installations.
• Commercial and industrial electrical distribution systems.
• IP65 enclosed switching installations requiring I-flange cable entries.
