Carling Technologies 4VA78 Mini Circuit Breaker

Carling Technologies 4VA78 Mini Circuit Breaker is a 15-amp miniature circuit protection device (part number 4VA78) designed to automatically interrupt current flow when an overcurrent condition is detected. Sized for compact panel integration, it provides dependable protection for control circuits, instrumentation panels, and small power-distribution configurations where space is at a premium. The 15 A rating denotes the continuous operating current the device is intended to carry under normal conditions; exact voltage rating, interrupting capacity, number of poles, and mounting style vary by variant within Carling’s 4VA family, so the official datasheet should be consulted to confirm compatibility with your system and required protection level. Typical applications include safeguarding low-voltage electrical circuits in industrial controls, machine panels, and enclosure-mounted sub-systems, where a robust, quick-acting switch remains essential for safeguarding wiring and components. For installation and replacement, verify that the 4VA78’s mechanical fit, electrical ratings, and terminal configurations match the existing equipment to preserve proper protection coordination and compliance with applicable standards.
