It carries a 20 A rating at 40 °C and holds that rating through 55 °C before derating to 19 A at 60 °C — useful to know if the breaker sits near other heat sources in a crowded enclosure. Breaking capacity is 75.6 kA at 240 VAC, 52.5 kA at 415 VAC, and 32 kA at 440 VAC. The 3-pole construction with a TM210 thermal-magnetic release suits it for feeder circuits where you need adjustable thermal and fixed magnetic trip coordination. It ships without a trip indicator or voltage trigger.
The breaker measures 70 mm deep, 76.2 mm wide, and 130 mm high — a standard 3-pole MCCB footprint that fits SENTRON panel-mounting systems and DIN-rail adapters. The 2.76 in × 3 in × 5.12 in dimensions confirm compatibility with existing cutouts in retrofit panels. The 12 W maximum power loss should be factored into enclosure thermal calculations, especially when grouping multiple breakers.
