In a crowded panel, that's the space of four single-pole MCBs side by side. The D curve and 40 A rating suit it for sub-distribution feeding a motor starter or a bank of discharge lighting — places where the start-up surge would pop a B or C curve breaker.","metaTitle":"Siemens 5SU1624-8RC40 RCBO 40 A 2-pole D Type A 300 mA","metaDescription":"Siemens 5SU1624-8RC40 RCBO, 40 A, 2-pole, 4-module, D characteristic, Type A, 300 mA residual current.
