It carries a continuous current rating of 32 A at 40 °C, and the rating holds to 32 A up through 50 °C before a mild derate starts at 55 °C (31 A) and 65 °C (30 A). Breaking capacity is what you check first for fault clearance. At 240 V AC it clears 75.6 kA; at 415 V AC it clears 52.5 kA; at 440 V AC it clears 32 kA; at 500 V and 690 V AC it clears 11.9 kA.
Dimensions: 130 mm high, 101.6 mm wide (4 inches), 70 mm deep. The 4-inch width matches the standard MCCB footprint for a 4-pole frame — it fits the same DIN-rail or panel-mount cutout as other 3VA 4-pole breakers. Front protection is IP40, which means tool-proof finger access but no washdown tolerance; keep it inside a closed enclosure. The TM220 release is thermal-magnetic, adjustable for thermal pickup and magnetic short-circuit threshold — no electronic trip unit, no communication function, no undervoltage release or ground-fault module on this variant. It's a straight line-protection breaker for feeder or branch circuits.
