FI/LS Protector Type A — 25 A, 30 mA, 10 kA
It integrates a 1+N-pole MCB with C-trip characteristic rated 25 A and a 30 mA residual-current device into a single 70 mm wide DIN-rail module. The Type A RCD detects pulsating DC fault currents and smooth DC residual currents up to 6 mA — needed on circuits with single-phase rectifiers, switched-mode power supplies, or variable-speed drives. The 70 mm depth (D=70 mm) means it fits flush in most consumer units and sub-distribution enclosures without protruding past the cover.
