It carries a TM210 thermal-magnetic release, rated 20 A at 40 °C with no derating needed up to 55 °C — at 60 °C it still holds 19 A, so it's stable across typical enclosure ambient conditions. Breaking capacity is 52.5 kA at 240 V AC, dropping to 32 kA at 415 V and 13.6 kA at 440 V — figures that place it solidly for North American 240/480 V distribution and IEC 415 V industrial mains. The breaker occupies a 76.2 mm (3 in) wide footprint on the DIN rail or panel mount, 130 mm tall, 70 mm deep. Maximum power loss is 12 W — modest for a 20 A frame, meaning less heat to vent inside a sealed enclosure.
Auxiliary switching and monitoring
Trip indicator is present, so a quick visual scan of the panel tells you which breaker opened.
