Why Choose the ABB OTP75A6B 37 kW 6-Pole Plastic Enclosed Switch-Disconnector?
The ABB OTP75A6B (1SCA022401R2710) is a heavy-duty six-pole plastic enclosed switch-disconnector designed for dependable local electrical isolation and load switching in industrial installations. Part of ABB's OTP enclosed safety switch range, it combines a 37 kW motor switching rating at 400 V AC, a red/yellow operating handle and an enclosure with IP65 ingress protection.
The OTP75A6B is designed for applications requiring the simultaneous switching of six electrical conductors. Its 80 A AC-23 operational current rating at 400 V AC makes it suitable for appropriately rated motor and inductive-load switching applications. The six-pole arrangement offers additional flexibility for industrial machinery, multi-circuit equipment and electrical installations requiring more than three switched conductors.
Featuring Type I flange cable entry provisions, the ABB OTP75A6B supports practical cable routing into its durable plastic enclosure. The enclosure measures 400 × 200 × 140 mm and incorporates a red/yellow manual operating handle. A normally open auxiliary contact and neutral terminal are included, while compatible cable entry flanges must be ordered separately.

Reliable Six-Pole Switching with IP65 Protection and Flange Cable Entries
The ABB OTP75A6B provides a manually operated switching and isolation solution for industrial electrical systems requiring six switched poles. Its 37 kW rating at 400 V AC and 80 A AC-23 operational current make it suitable for appropriately selected motor and inductive-load applications. The six-pole configuration enables multiple conductors to be switched through one common operating mechanism.
The IP65 plastic enclosure helps protect the switching mechanism against dust and water jets when correctly installed. Its Type I flange entry arrangement accommodates compatible cable entry accessories, which must be selected and ordered separately. The included normally open auxiliary contact can be incorporated into suitable indication or control circuits, while the neutral terminal supports appropriate wiring arrangements.
Electrical designers should confirm the applicable switching duty, circuit protection, conductor arrangements and installation requirements before commissioning. Where the switch is used for maintenance isolation, the complete installation must provide the necessary means of secure disconnection and verification.
Typical Applications
- Industrial machinery local isolation.
- Six-pole electrical switching installations.
- Three-phase motor equipment requiring additional switched conductors.
- Industrial pumps, fans and ventilation systems.
- Manufacturing and production machinery.
- Conveyor and material handling equipment.
- Industrial electrical distribution systems.
- Multi-conductor equipment isolation.
- Electrical installations requiring IP65 enclosed switching.
- Machinery installations requiring flange-type cable entries.
- Commercial and industrial plant equipment.
- OEM electrical and mechanical equipment assemblies.
