1SCA152717R1001 ABB 16 A 3-Pole IP65 ATEX EMC Enclosed Safety Switch

Why Choose the ABB OTA16S3YX 16 A ATEX EMC Safety Switch?

The ABB OTA16S3YX, order number 1SCA152717R1001, is a specialist 16 A, 3-pole ATEX EMC enclosed safety switch designed for dependable load breaking and electrical isolation in potentially explosive and dusty industrial environments. It combines ABB switch-disconnector technology with a rigid die-cast aluminium enclosure, IP65 protection and a highly visible red-yellow operating handle.

Designed for three-phase motor and machinery applications, the OTA16S3YX provides an AC-23A rating of 16 A / 7.5 kW at 380–415 V. It is designed for potentially explosive atmospheres in accordance with the ATEX framework and is classified Ex tc III T70°C Dc for use in Zone 22, making it suitable for locations where combustible dust can create a hazardous atmosphere.

The OTA16S3YX is EMC approved and includes a 1NO auxiliary contact, PE terminal, threaded top and bottom cable entries, cable glands, cable-entry plugs and a safety-switch label. Its compact aluminium enclosure and red-yellow I-O / ON-OFF handle provide a complete local isolation solution for hazardous-area machinery and plant.
