That standard covers low-voltage switchgear for overcurrent protection — so this MCCB is the right call for a distribution board or feeder circuit where you need a 100 A thermal-magnetic trip in a compact 4P footprint. The cable cross-section range of 50 to 185 mm² and a tightening torque of 10 N·m tell you this breaker takes heavy-gauge copper — sized for a 100 A feeder, not a subfeed. That lug range covers most 70–120 mm² builds; if you're landing 185 mm², verify the lug barrel depth clears the enclosure gland plate.","metaTitle":"MGNCB1004 Isobar B MCCB, 100 A 4P, BS EN 60947-2","metaDescription":"MGNCB1004 Isobar B molded case circuit breaker, 100 A at 415 V AC, 4 poles.
