Allen-Bradley 1492-CB3 Three-Phase Circuit Breaker

Allen-Bradley 1492-CB3-G050 is a three-pole, DIN-rail-mount molded-case circuit breaker in the 1492 family, designed to protect three-phase circuits in industrial control panels. This G050 variant is rated at 5 A and configured for 480 V AC systems, with a common-trip mechanism that interrupts all three poles simultaneously. As a DIN rail‑mount CB3, it supports compact installation in PLC panels and can be used with three-pole commoning links to coordinate protection across multiple devices. The 1492-CB line is a molded-case breaker, intended for overcurrent protection of three-phase power distributions, offering a space-saving solution for protecting 480 VAC loads in modern control enclosures. Its rugged design and standard DIN-rail mounting simplify integration into existing panel layouts, enabling reliable interruption of fault currents across all three phases while maintaining alignment with industry practices for modular automation equipment.
