Allen-Bradley 1492-SP2B020 Molded Case Circuit Breaker

Allen-Bradley 1492-SP2B020 Molded Case Circuit Breaker is a two-pole protection device rated for 20 A, part of the 1492-SP family from Allen-Bradley (Rockwell Automation). It employs a B-type trip curve, designed to trip under overload conditions and certain short circuits in resistive to lightly inductive loads, helping protect conductors and connected equipment. The molded-case design and two-pole configuration are suited for installation in industrial control panels and other electrical enclosures where space is at a premium, providing reliable interruption of fault currents to safeguard circuits feeding motors, solenoids, PLC power rails, and other automation components. As a member of the 1492-SP series, the 1492-SP2B020 is intended for applications requiring quick, predictable protection with a 20 A rating, and it leverages Allen-Bradley’s established compatibility with other 1492-SP accessories and replacement parts for streamlined maintenance and panel upgrades. Typical deployment scenarios include machinery control, packaging lines, conveyors, and general automation panels where compact, dependable overcurrent protection is essential.
