WTM1-250 Moulded Case Circuit Breaker (MCCB) for DC Distribution
Pair the WTM1-250 with high-current DC feeders in solar power plants, energy storage systems and industrial DC distribution boards.
WTM1-250 is a moulded case circuit breaker (MCCB) for 100A to 250A DC circuits, compliant with IEC 60947-2, IEC 60947-1, GB 14048.1 and GB 14048.2.
Current ratings
Rated current covers 100A, 125A, 140A, 160A, 180A, 200A, 225A and 250A, with the WTM1 family extending from 16A to 1250A across six frame sizes.
DC voltage levels
DC operating voltage reaches 550V in 2P, 750V in 3P and 1000V or 1500V in 4P configuration, matching solar string and battery bank voltages.
Breaking performance
Breaking time of 200ms and arcing distance of at least 50mm deliver stable interruption of DC faults, backed by 8kV impulse withstand voltage and 1500V rated insulation voltage.
Service life
Mechanical lifespan reaches 7,000 operations and electrical lifespan 2,000 operations, with operating temperature from -25℃ to +50℃ and IP20 protection.
Accessories
OF auxiliary contacts, SD alarm contacts and MX shunt trip are supported, and the breaker serves as an isolating device without a separate switch.
