1SCA152731R1001 ABB ATEX EMC Safety Switch 40 A 4 Pole 11 kW

Why Choose the ABB OTA40S4YX ATEX EMC Safety Switch?

The ABB OTA40S4YX is a robust ATEX EMC enclosed safety switch-disconnector designed for dependable local isolation of electrical loads in demanding industrial and potentially explosive environments. With ABB product ID 1SCA152731R1001, this switch combines a 40 A enclosed load-break design, four-pole switching and a durable die-cast aluminium enclosure.

As part of the ABB OTA ATEX enclosed safety switch range, the OTA40S4YX is engineered for applications requiring reliable isolation, environmental protection and EMC compatibility. Its IP65 enclosure, red/yellow rotary operating handle, PE terminal, threaded cable entries and supplied cable glands provide a practical enclosed switching solution for industrial machinery and process equipment.

With a 40 A enclosed rating and a rated operational motor power of 11 kW at 380–415 V AC-23A, the OTA40S4YX is suitable for isolating substantial industrial loads. The switch features four poles, a factory-mounted 1NO auxiliary contact and top-in/bottom-out terminal positioning, while its red/yellow handle provides clear visual identification for safety and maintenance isolation.

Reliable Isolation for Hazardous Industrial Areas

Safety switch-disconnectors such as the ABB OTA40S4YX provide a clearly operated local means of disconnecting electrical equipment from its power supply for maintenance, servicing and safety procedures. Its four-pole construction enables multiple conductors to be isolated simultaneously, while the top-in/bottom-out terminal arrangement supports practical cable routing in industrial installations.

The OTA40S4YX combines a rigid die-cast aluminium enclosure with IP65 protection, a red/yellow safety handle and EMC approval. Its enclosed ATEX design makes it particularly suitable for industrial machinery, conveyors, processing equipment and other installations where robust local isolation is required in potentially explosive environments.

Typical Applications

• Industrial machinery safety isolation.
• ATEX industrial installations.
• Conveyor and material handling systems.
• Mills and industrial processing equipment.
• Manufacturing and production machinery.
• Motor circuits up to 11 kW at 415 V where the specified switching duty is appropriate.
