It is designed for 230 V AC circuits and occupies 2.5 TE (module-width units) on a DIN rail. The \"FI PROTECTOR>N<\" designation indicates it is a compact, non-switched RCD block, and the Type A classification means it detects pulsating DC residual currents as well as sinusoidal AC — the standard requirement for circuits with single-phase rectifiers, switched-mode power supplies, or frequency converters. The 80 A rated current sets the thermal capacity for the main circuit — sized for a 3-phase (or single-phase) feeder up to that load, not for motor starting duty. The 0.3 A IΔn is the trip threshold for earth leakage; it is higher than the common 30 mA (0.03 A) used for personal protection and is typically chosen for circuits where a higher standing leakage is expected (e.g., long cable runs, industrial equipment with EMC filters). Type A selectivity (PSE/SSF in the description) means this device is coordinated to discriminate with downstream RCDs — a fault on a subcircuit trips the downstream device, not this main RCD, keeping the rest of the panel live.","metaTitle":"Siemens 5SM1617-6BA RCD Type A, 80A 2-Pole 0.3A IΔn","metaDescription":"Siemens 5SM1617-6BA FI protector Type A (PSE/SSF), 80A 2-pole, IΔn 0.3A, 230V, 2.5TE.
