ABB T4L250TWS4 Industrial Molded Case Circuit Breaker

ABB T4L250TWS4 is a Tmax molded-case circuit breaker designed for industrial three-phase power distribution, rating 250 A and 600 V nominal for AC operation. The TWS4 variant indicates shunt-trip capability, delivering a fast trip path alongside the standard thermal-magnetic protection, suitable for remote shutdown in control schemes. This 3-pole MCCB provides up to 100 kA short-circuit interrupting capacity at 480 V, making it appropriate for feeders and panelboard protection in medium-fault-current environments. The T4L family is optimized for reliable protection of industrial loads in 3-phase networks.
