TE Connectivity W28-XQ1A-3 Miniature Circuit Breaker

The TE Connectivity W28-XQ1A-3 is a one-pole Potter & Brumfield thermal circuit breaker with a push-to-reset actuator, part of TE’s W28 family. It is rated for 3 A at up to 250 VAC or 32 VDC, with a 1,000 A interrupt capacity at those ratings, and uses a series-trip mechanism for overload protection. Terminations are 6.35 mm (0.250 in) quick-connect tabs, and it mounts in panels via snap-in mounting with a black actuator and bezel. At 200% overload, it trips in 2.2 to 15 seconds, making it suitable for protecting low-voltage control circuits, power supplies, and other panel-mounted applications where compact, single-pole protection is needed.
