Thermal Magnetic E150 — ABB’s reliable and efficient molded case circuit breakers equipped with a thermal-magnetic trip system. These circuit breakers are widely used in switchboards, motor control centers, lighting systems, and power panelboards. Molded case circuit breakers in individual enclosures are also utilized in numerous applications. In cases of overload or short circuit, the breaker trips, opening the circuit and protecting the conductors, eliminating the need for fuse replacement. Once normal conditions are restored, the breaker can be closed ("ON") again. The product offers proven reliability, cost-effective solutions, and flexibility for various applications.
