The A9DGA610: Rated 10 A with a B-curve (magnetic trip between 3 and 5 x In) means it's sized for residential or light commercial final circuits — lighting, socket outlets — where inrush is low. Limitation class 3 (EN/IEC 61009-2-1) means it lets through limited energy under short-circuit — good for protecting downstream wiring and loads. Integrated earth-leakage protection at 10 mA sensitivity (the lowest standard threshold) makes this unit suitable for circuits requiring high personnel protection — think wet areas, construction-site sockets, or medical locations where a 30 mA device would be too slow. The thermal-magnetic trip unit handles both overload (thermal bimetal) and short-circuit (magnetic solenoid) in one package.
Tunnel-type terminals accept 1 to 16 mm² rigid or 1 to 10 mm² flexible cable; strip length 14 mm. Tightening torque 2 N·m top or bottom. The 9 mm connection pitch between phase and neutral matches the Acti9 modular system for busbar bridging.
