Product details

Its TM210 thermal-magnetic release provides fixed overload and short-circuit protection without adjustable trip settings — a straightforward fit for standard feeder circuits where coordination is set by the breaker rating, not field tuning. Breaking capacity hits 121 kA at 240 V AC and 75.6 kA at 415 V AC, giving substantial SCCR headroom for high-fault installations.

This part carries a current-production lifecycle status.

Integration Notes

The TM210 release is non-interchangeable, so verify the 25 A rating matches your load before mounting. Insulation voltage rated 500 V; AC operating voltage 415 V, DC operating voltage 250 V.
