The Schneider Electric Easy9 EZ9F34206 is a 2-pole miniature circuit breaker rated 6 A with a C-curve trip characteristic (magnetic trip between 5 and 10 times In). The 4.5 kA breaking capacity at 230/400 V AC per IEC 60898-1 means it safely interrupts a fault current up to that level without welding contacts or cascading upstream — adequate for most residential and light commercial distribution boards where the prospective short-circuit current stays under that threshold. Thermal-magnetic trip technology covers both overload (thermal bimetal) and short-circuit (solenoid) protection in one unit. For motor circuits or transformers with higher inrush, a D-curve would be preferred; for purely resistive loads, a B-curve could be used. This part is sized for a 6 A final subcircuit.
The 36 mm width occupies 4 module pitches at 9 mm each — standard for a 2-pole MCB in a distribution board. Tunnel-type terminals accept 1–25 mm² rigid or 1–16 mm² flexible cable; tighten to 2 N·m. IP20 finger-safe terminals suit enclosed panel use.
