The W28 series thermal circuit breaker is a compact single-pole breaker with push-to-reset operation. One of the most popular circuit breakers, it is designed to fit in about the same space as a glass-cartridge fuse-holder. The W28 is available in ratings from one-quarter amp up through 20 amps, and can operate up to 32 volts DC or 250 volts AC. It conveniently snaps into a panel from the front and has quick-connect terminals. W28 is recognized by several agencies including UL, CSA, VDE, DEMKO and SEV. Its small size and low cost makes the W28 appealing for an extremely broad range of applications.
