Its 4-pole construction handles three-phase plus neutral, and the interrupting ratings climb to 76 kA at 240 V AC — enough to clear high-fault scenarios in distribution panels without upstream coordination headaches. At 415 V the breaker still holds 53 kA, dropping to 32 kA at 440 V and 5 kA at 500 V or 690 V. That steep fall-off above 500 V means this variant is best suited for 240 V or 400/415 V lineups where the available fault current stays under 53 kA. The TM210 release is fixed thermal-magnetic — no electronic adjustment, no communication module, no voltage-trip or ground-fault monitoring. It is a straightforward line-protection breaker for panels where simplicity and reliability beat configurability.
At 55 °C it derates to 78 A, then 77 A at 60 °C, 75 A at 65 °C, and 74 A at 70 °C. That flat top through 50 °C is useful for enclosures with moderate heat rise — no need to oversize for a warm panel. Height is 130 mm, width 4 in — a standard footprint for 4-pole MCCBs in North American and IEC panels. No undervoltage release or shunt trip is fitted on this order code — if you need those, this is not the variant.
