Allen-Bradley 1492-CB3 3 Pole Circuit Breaker

Allen-Bradley 1492-CB3 is a three-pole motor-disconnecting circuit breaker from the 1492-CB family, designed to protect and isolate three-phase motors in control panels. It is rated for 10 A and supports up to 5 HP motor loads, providing overload protection with an instantaneous magnetic trip for fault current. This device combines switching and protection in a compact unit suitable for motor circuits, enabling safe servicing and rapid disconnection when faults occur. The 1492-CB3 uses a three-pole configuration for balanced three-phase applications and carries UL 508 and CSA listings, aligning with common industrial electrical standards. Typical applications include motor-driven equipment such as conveyors, pumps, and fans, as well as other small-to-mid-sized three-phase motors where reliable protection and isolation are required.
