Allen-Bradley 1492-SP2C050 Miniature Circuit Breaker

Allen-Bradley 1492-SP2C050 is a two-pole supplementary protector from the 1492-SP family, designed for compact, reliable overcurrent protection of low-current circuits in industrial control panels. It is a 5 A, 2P device with a C-trip characteristic, employing a thermal-magnetic trip mechanism and featuring a non-interchangeable trip unit with line and load lug terminals for straightforward wiring. This Bulletin 1492-SP protective device is specified for up to 480 V AC (regional variants exist, including 277 V configurations) and carries a short-circuit rating of up to 10 kA at 480 V, offering fast response to overloads and short circuits while enabling selective coordination with upstream devices. The SP2C050 designation identifies two poles and a C-type trip curve, and the unit is compatible with 1492-SP installations for 1-phase applications, making it suitable for protecting downstream control circuits, relays, sensors, and other auxiliary loads within industrial equipment. As part of the 1492-SP family, it combines a compact molded-case design with dependable protection functions—long-time and instantaneous trip features—and secure wiring via line/load side lug terminals. This model is commonly used where small footprint and precise 5 A protection are required, such as in control panels, machine controllers, and other automation assemblies.
