Thermal-magnetic circuit breaker provides single-pole overload and short-circuit protection with a 25 A current rating. The TMC 91 H series uses toggle actuation and mounts on DIN/EN 50022 rails in 35 mm x 7.5 mm or 35 mm x 15 mm profiles. Rated operation covers AC 277/480 V, with CSA ratings to AC 347/600 V and DC ratings listed for the series. The breaker has high rupture capacity up to 10 kA at AC 277/480 V and supports line conductors up to 35 mm² or AWG 2.
