£254.50
The ABB OKA25S3G (1SCA142685R1001) is a robust 3-pole EMC enclosed switch disconnector designed to provide safe electrical isolation in demanding industrial applications where electromagnetic compatibility (EMC) is essential. Part of ABB's premium OKA aluminium enclosed switch disconnector range, it combines dependable switching performance with a highly durable die-cast aluminium enclosure for long service life.
Manufactured from a corrosion-resistant die-cast aluminium alloy (Silumin) with a polyester-coated finish, the enclosure is rated IP65, making it suitable for harsh indoor and outdoor environments. The enclosure includes compression cable glands, PE and neutral terminals, a screwed interlocked cover and a handle that can be padlocked in both the OFF and ON positions. When fitted with EMC cable glands, the enclosure is fully EMC approved.
Rated at 25 A AC-22A and 20 A AC-23A at 415 V AC, the OKA25S3G is ideal for isolating motors, machinery, HVAC equipment, pumps and industrial distribution systems where reliable switching and EMC protection are required.
The ABB OKA25S3G provides reliable manual isolation for industrial electrical systems whilst offering excellent resistance to corrosion, impact and environmental conditions. The die-cast aluminium enclosure, interlocked cover and EMC compatibility make it particularly suitable for installations involving variable speed drives, automation equipment and sensitive electronic systems.
