Easy9 miniature circuit breaker grey

Start by matching poles to your circuit: use 1P for single‑phase 230 V, 3P for three‑phase 400 V, or 4P for mixed loads. Then pick a current rating that fits your load (such as 6 A, 16 A, 20 A, 25 A or 32 A) and choose a C curve for general‑purpose protection. Check the interrupting capacity of up to 6000 A and ensure the housing is flame‑retardant‑thermoplastic as used in the Schneider Easy9 family. Finally, confirm you’re selecting the easy9 miniature circuit breaker grey variant that matches your panel’s DIN rail system.

A C curve means the device trips at about 5 to 10 times the rated current, making it suitable for general‑purpose circuits with light to moderate inrush. For the easy9 miniature circuit breaker grey, this curve is ideal for lighting, outlets, and mixed residential loads to provide reliable protection with minimal nuisance trips. If you frequently power motors or equipment with high inrush, consider a different characteristic, but for typical home circuits in the Easy9 line, a C curve offers balanced protection.

Choose the pole count based on the circuit’s phase: 1P for single‑phase 230 V circuits, 3P for three‑phase 400 V systems, or 4P for shared neutral or multi‑load configurations. The easy9 miniature circuit breaker grey range from Schneider covers these configurations so you can align your panel design with consistent protection while preserving the same C‑curve characteristics and a 6000 A breaking capacity.

Install on a compatible DIN rail in a flame‑retardant‑thermoplastic enclosure and tighten terminals to the rated torque. Verify compliance with IEC/EN 60898‑1 standards and match the voltage rating (230 V or 400 V) to your circuit. Keep the unit clean and dry, avoid aggressive cleaners, and when replacing, choose the same easy9 grey model from Schneider to maintain electrical compatibility and safety.

For typical home circuits, start with 1P 6 A, 1P 16 A, or 1P 20 A variants in the easy9 miniature circuit breaker grey family, all with a C curve for general protection. For larger or three‑phase loads, consider 3P configurations such as 25 A or 32 A within the Easy9 line, still built with flame‑retardant‑thermoplastic housing and the same 6000 A breaking capacity. Always ensure the voltage rating matches your supply (230 V or 400 V) and panel configuration.
