The TM210 thermal-magnetic release handles overloads and short-circuits without an electronic trip unit — no auxiliary power needed, no communication function. That keeps the wiring simple and the failure mode predictable.
Breaking capacity varies by system voltage: 52.5 kA at 240 V, 32 kA at 415 V, 13.6 kA at 440 V, and 7.5 kA at 500 V and 690 V. At 415 V the 32 kA rating covers most industrial transformer-fed panels. At 690 V the 7.5 kA figure is lower — verify the available fault current if feeding from a high-impedance source or a large transformer.
Fit and panel integration
Width is 76.2 mm (3 in), depth 70 mm (2.76 in), height 130 mm (5.12 in) — standard SENTRON 3VA1 footprint. The 70 mm depth leaves clearance behind most enclosure gland plates.
