The 'Long Tail' variant extends the neutral conductor for panel wiring convenience. The C50 curve means the thermal trip holds up to 5× rated current (250 A) for short overloads, then snaps — sized for motor or lighting circuits with moderate inrush. The 30 mA type A residual-current element catches both sinusoidal AC fault currents and pulsating DC fault currents, which covers modern electronics and variable-speed drives downstream.","metaTitle":"5SU9307-7QS50 RCBO Crabtree Polestar, 16 kA, 30 mA, C50","metaDescription":"Siemens 5SU9307-7QS50 RCBO, Crabtree Polestar, 16 kA type A, 30 mA, C50, Long Tail.
