32 A, 4-pole MCCB with TM240 release — line protection for distribution panels
Breaking capacity scales with system voltage: 75.6 kA at 240 V AC, 52.5 kA at 415 V AC, 32 kA at 440 V AC, and 11.9 kA at both 500 V and 690 V AC. At 65 °C it still holds 30 A; only above 70 °C does it need to be derated below 30 A.
The breaker measures 101.6 mm wide (4 in), 130 mm high (5.12 in), and 70 mm deep (2.76 in). Four-pole frame means it occupies the same panel footprint as a standard 4-pole MCCB — no unusual cutout or busbar spacing required. Maximum power loss is 10.6 W — negligible for thermal management in a standard distribution enclosure.
