OT250E22C MANUAL CHANGE_OVER SWITCH

The OT250E22C is a robust, manually operated 4-pole change-over switch rated for a current of up to 250 A. Engineered for base mounting applications, it accommodates operational currents across multiple voltage levels—250 A at 380–415 V, 500 V, and 690 V under AC-21A, AC-22A, and AC-23A conditions. Its high-rated insulation voltage (Ui) of 1000 V and impulse withstand voltage (Uimp) of 12 kV ensure reliability in demanding industrial environments.

 

Designed to meet IEC standards with pollution degree classification of level 3, the OT250E22C offers front-side protection rated at IP20. The top-to-bottom or bottom-to-top terminal configuration simplifies wiring while utilizing screw terminals with defined tightening torque per IEC 60947-1 between 15 and 22 N·m. Each pole operates efficiently with power loss values set at just 6.5 W under full load conditions.

 

Operational versatility is supported through an open transition type switching mechanism positioned between the poles for dependable manual operation. The switch can withstand short-time currents up to 8 kiloamperes RMS for one second, ensuring resilience during transient overload scenarios.

 

Physical dimensions include a width of 205 mm (8.07 in), height of 150 mm (5.91 in), depth/length of approximately160 mm (6.30 in), and a net weight of approximately 3.6 kg (7.94 lb). All accessories such as handle and shaft must be ordered separately under compatible configurations noted by ABB standards.

 

This unit adheres to European directives including RoHS compliance pursuant to EU Directive amendments from July 2019 alongside certification from DNV regulatory bodies for marine-grade suitability where applicable within industrial automation fields like oil & gas processing plants or marine electrical systems infrastructure assemblies professionals looking scalable dependability system distribution /scenarios
