It is a 3-pole unit rated 100 A continuously at 40 °C ambient, with a TM210 thermal-magnetic release (the '210' indicates the thermal element is fixed at 100 A, magnetic pickup at roughly 10× In). Breaking capacity is 52.5 kA at 240 V, 32 kA at 415 V, 13.6 kA at 440 V, and 7.5 kA at both 500 V and 690 V — figures that govern where this breaker can be applied without cascading upstream.
Rated current holds flat at 100 A from 40 °C through 50 °C, then steps down: 98 A at 55 °C, 96 A at 60 °C, 94 A at 65 °C, 91 A at 70 °C. Dimensions are 130 mm height, 76.2 mm width, 70 mm depth — a 3-pole MCCB footprint that fits standard SENTRON panel cutouts and busbar systems.
Auxiliary contacts and insulation
Rated insulation voltage is 800 V, and the operating temperature range spans -25 °C to +70 °C, with storage from -40 °C to +80 °C.
