It is rated for 80 A continuous current at 380...415 V AC 50/60 Hz on a 4-pole network, with a 300 mA earth-leakage sensitivity and Type A protection class (picks up sinusoidal AC and pulsating DC residual currents).
Neutral is on the left. Terminals accept up to 35 mm² rigid or 25 mm² flexible on the front, with a stripping length of 14 mm and a tightening torque of 3.5 N.m. The toggle actuator and padlocking provision are standard for panel builders who need lockout/tagout on the RCCB itself.
Type A detection covers the majority of modern loads with single-phase rectifiers (computers, VFDs, LED drivers) that generate pulsating DC leakage. The instantaneous trip (no time delay) means it responds immediately to the residual current — fine for the RCCB at the origin of an installation, but if you need selectivity with downstream RCCBs you would look for an S-type (time-delayed) variant. The 6 kV impulse withstand voltage (Uimp) and 250 A 8/20 µs surge withstand confirm it survives common lightning-induced transients without nuisance tripping.
The electrical endurance is 10,000 cycles under AC-1 (resistive load); mechanical endurance is 20,000 cycles.
