Its headline interrupting capacity — 53 kA at 240 V AC — drops to 32 kA at 415 V and 14 kA at 440 V, so the voltage at the fault point governs whether this breaker clears a high-fault event without upstream coordination issues. At 500 V the rating is 8 kA, which still covers most industrial motor branch circuits. The TM210 thermal-magnetic release is fixed at 25 A continuous up to 50 °C ambient; above that it derates to 24 A at 55–60 °C and 23 A at 65–70 °C, so a panel sitting near a hot transformer or in a non-conditioned enclosure needs that headroom factored in.
The breaker measures 70 mm deep, 101.6 mm wide, and 130 mm high — a 4-pole MCCB that fits standard DIN-rail or panel-mount enclosures. The 101.6 mm width (4 inches) matches the common 4-pole MCCB footprint, so it drops into existing cutouts without rework. No motor drive or communication function is fitted; it is a straight thermal-magnetic device with no add-on options for remote trip or ground-fault monitoring.
