The 2-module (2TE) width fits standard DIN-rail enclosures. The 40 A rating sizes this RCD for a 40 A final sub-circuit — typically feeding a group of socket outlets or a fixed load up to 9.2 kW at 230 V. The 30 mA sensitivity is the IEC 60364-4-41 threshold for supplementary protection against direct contact; it will trip on leakage currents above 30 mA, which is below the let-go threshold for adults. For circuits with variable-speed drives, LED drivers, or single-phase rectifiers, a Type A or Type F RCD would be required. ## Integration notes The 2TE (36 mm) width on a 55 mm deep housing fits standard DIN-rail distribution boards. The 2-pole configuration (L + N) is correct for single-phase 230 V circuits. Terminals accept copper conductors sized for the 40 A rating; verify the upstream overcurrent protective device is coordinated per the manufacturer's selectivity tables.","metaTitle":"Siemens 5SM1314-0FD FI-Protector, Type AC, 40A 2-Pole 30mA 2","metaDescription":"Siemens 5SM1314-0FD FI-Protector, Type AC, 40A, 2-pole, 30mA rated residual current, 230V, 2TE.
