Its TM210 thermal-magnetic release handles overload and short-circuit trip curves without external controls. With a 187 kA interrupting rating at 240 V AC — dropping to 121 kA at 415 V and 75.6 kA at 440 V — this breaker provides serious fault-current headroom for high-capacity feeders where selectivity with downstream devices matters. The front face is IP40-protected, so it's suited for panel-mount applications where the enclosure provides the environmental seal.
Interrupting capacity across voltage levels
The interrupting ratings span from 187 kA at 240 V down to 17 kA at 500 V and 690 V. That steep drop-off means at higher voltages the breaker's available fault-current handling is much lower — coordination studies should use the 500 V / 690 V figure where applicable. At 415 V (common in European industrial systems) the 121 kA rating still exceeds most transformer-fed fault levels.
