Its continuous current rating Iu is 16 A, and it holds that rating flat from 40 °C through 55 °C; at 60 °C it derates to 15 A, and at 70 °C it still delivers 15 A — useful when the breaker sits in a warm enclosure near other heat sources. The TM210 overcurrent release combines a thermal element for overload protection and a magnetic element for short-circuit protection. The 210 designation indicates a fixed thermal rating with an adjustable magnetic trip range (typically 5–10x In for this family), letting you dial in the instantaneous pickup to coordinate with downstream devices.
Breaking capacity across voltages — selectivity headroom
This MCCB delivers 52.5 kA at 240 V AC, 32 kA at 415 V, 13.6 kA at 440 V, and 7.5 kA at both 500 V and 690 V. The steep drop above 415 V reflects the physics of arc extinction in air; at 690 V the 7.5 kA figure still covers most industrial motor-drive branch circuits.
Panel integration — dimensions and mounting
The breaker measures 101.6 mm wide, 130 mm high, and 70 mm deep — a 4-pole footprint that fits standard SENTRON 3VA panel cutouts and busbar systems. Front IP40 protects against tool entry in the enclosure; the rear and sides are protected by the panel itself.
