Type A residual-current detection covers pulsating DC fault currents and sinusoidal AC — the common choice for circuits with single-phase rectifiers, switching power supplies, or electronic loads that generate smooth DC ripple.
The higher IEC figure applies when the device is used as a circuit breaker in industrial distribution; the EN figure governs residential or commercial final circuits. Either way, the 15 kA rating gives headroom for coordination with an upstream 25 kA or 36 kA main breaker in a typical panel.
Snap-on DIN-rail mount, 36 mm wide (2 MW), 70 mm deep. Mounting position any, so it fits horizontal or vertical busbars without derating.
