ABB OTHV250E12WP three-pole 250 A front-operated base-mounted switch disconnector for industrial electrical isolation in 800 to 1000 V AC systems, supplied with a pistol handle and operating shaft.
The ABB OTHV250E12WP, product code 1SCA162975R1001, is a robust three-pole switch disconnector designed for safe electrical isolation and dependable switching in high-voltage industrial AC systems. As part of the advanced ABB OTHV switch disconnector series, it is engineered for applications operating at voltages between 800 and 1000 V AC.
This manually operated switch disconnector combines a compact base-mounted construction with reliable switching performance. Its front-operated mechanism supports straightforward installation inside switchboards, control panels and industrial electrical enclosures, while its 250 A conventional thermal current rating makes it suitable for demanding power distribution circuits.
Unlike the standard OTHV250E12W version, the OTHV250E12WP includes a black pistol handle and operating shaft. This provides a more complete installation package and simplifies the specification of an externally operated isolation solution for electrical cabinets and machinery enclosures.
Switch disconnectors such as the ABB OTHV250E12WP provide a secure means of isolating electrical equipment from its power supply. This helps engineers and maintenance personnel safely inspect, service and repair machinery, switchboards and industrial electrical systems.
The OTHV series is developed for installations requiring dependable switching at elevated AC voltages. Its robust construction, high current capacity and strong short-circuit withstand characteristics make it suitable for demanding industrial environments where electrical safety and operational reliability are essential.
