The Type A designation means it detects pulsating DC residual currents in addition to sinusoidal AC — essential for circuits supplying single-phase rectifiers, switched-mode power supplies, or variable-speed drives where standard AC-only RCDs would be blind to the fault. The 2-module width (2 TE) and 55 mm depth fit standard DIN-rail enclosures. ## Deployment context — where this RCD belongs The Type A characteristic makes it the right choice for sub-distribution boards feeding IT equipment, EV chargers, or any load with downstream rectification where the manufacturer specifies Type A protection. The 0.3 A IΔn provides a balance between personnel protection and nuisance-trip immunity on circuits with natural leakage.","metaTitle":"Siemens 5SM1614-6BA FI Protector Type A, 40A 2-Pole 0.3A 230","metaDescription":"Siemens 5SM1614-6BA FI Protector Type A (PSE/SSF), 40A 2-pole, 0.3A IΔn, 230V, 2TE.
