Why Choose the ABB 1SCA142683R1001 OKA16S3G EMC Enclosed Switch-Disconnector?
The ABB 1SCA142683R1001, order code OKA16S3G, is a 3-pole EMC-compatible enclosed switch-disconnector designed for safe isolation and switching in industrial and commercial electrical installations. As part of the ABB 311027-OT Switches product group, it combines an ABB switch-disconnector with a robust aluminium enclosure to provide dependable local isolation in demanding environments.
The OKA16S3G is rated at 16 A AC-22A at 415 V and 16 A AC-23A at 415 V, making it suitable for switching resistive, mixed and motor loads. Its 3-pole configuration provides simultaneous isolation of three-phase conductors, while the enclosed design provides IP65 protection against dust and water ingress.
The switch is housed in a rigid aluminium-alloy enclosure with a light grey body and dark grey cover. It features top and bottom cable entries, an interlocked cover, a black rotary operating handle and included PE and neutral terminals. The enclosure is EMC compatible when suitable EMC cable glands are used, making the OKA16S3G particularly suitable for installations where electromagnetic compatibility is important.
