ABB ESB43015L U Industrial Low Voltage Circuit Breaker

ABB ESB43015L U is an industrial low-voltage circuit breaker rated for 15 A at up to 480 V, designed to protect electrical circuits in industrial power-distribution systems. This ABB device interrupts current during overload or short-circuit events to help safeguard wiring and connected equipment in 480 V AC installations. It is suitable for integration in distribution panels, motor control centers, and other industrial enclosures that require reliable, compact protection for moderate-load circuits. Typical applications include machine control panels, conveyors, and process equipment where dependable overcurrent protection is essential to maintain system uptime. As part of ABB’s ESB family of protective devices, the ESB43015L U is intended to support standard protection schemes alongside upstream protective coordination, enabling consistent behavior across ABB protection products in commercial and light-industrial environments.
