Why Choose the ABB OTL16A3B Safety Switch?
The ABB OTL16A3B is a compact and robust steel sheet enclosed safety switch-disconnector designed to provide dependable local isolation of three-phase motors, machinery and industrial electrical loads. With ABB product ID 1SCA022575R1630, this three-pole safety switch combines reliable load-breaking performance with a durable metal enclosure for industrial applications.
As part of the ABB OTL enclosed safety switch series, the OTL16A3B features an IP65 enclosure and a highly visible red/yellow operating handle for clear identification as a safety isolator. The enclosed construction provides protection against dust and water ingress, while the operating mechanism supports secure isolation during maintenance and servicing.
With a rated operational current of 16 A at 415 V AC-23A and a motor switching capability of 7.5 kW at 400–415 V, the OTL16A3B is well suited to smaller industrial motors and machinery. The switch has a three-pole configuration, includes a 1NO auxiliary contact and uses a bottom B-flange cable-entry arrangement for practical installation.
