Line protection breaker with a 630 A backbone
The TM210 overcurrent release handles the thermal-magnetic trip curve, so it responds to sustained overloads and short-circuit events in one package — no separate trip unit to source.
Short-circuit ratings that cover the voltage range
At 240 VAC this breaker interrupts 187 kA. At 415 V and 440 V it holds 121 kA, and at 500 V it still manages 76 kA. That gives you selectivity headroom for most industrial services without cascading upstream.
