1SCA022612R9480 ABB 63A 4-Pole Metal Enclosed Safety Switch

Why Choose the ABB OTL63A4M 63A 4-Pole Metal Enclosed Safety Switch?

The ABB OTL63A4M, order code 1SCA022612R9480, is a robust 63 A four-pole metal enclosed safety switch designed for dependable load breaking and electrical isolation of industrial machinery, motors and electrical equipment. As part of ABB's Metal Enclosed (Loadbreak) product group, it combines ABB switching technology with a durable steel-sheet enclosure for demanding industrial installations.

Designed for local safety isolation, the OTL63A4M features a highly visible red-yellow pistol handle with I-O / ON-OFF indication. The grey enclosure is equipped with hinges and a lock, while cover interlocking and a defeatable interlock provide a practical arrangement for maintenance access. The switch is also supplied with 1 NO auxiliary contact and a PE terminal.

With an authoritative 63 A rating and four-pole configuration, the OTL63A4M is suitable for applications requiring simultaneous four-pole isolation. Its AC-23A motor rating is 30 kW / 63 A at 415 V and 30 kW / 35 A at 690 V, while the IP65 steel-sheet enclosure and top-and-bottom cable entries provide installation flexibility.
