Overview
The EZ9F53210 is a Schneider Easy9 miniature circuit breaker rated 10 A, 2-pole, C-curve, with a 3 kA breaking capacity at 400 V AC. It uses a thermal-magnetic trip unit and clips onto a DIN rail.
Selection and sizing
The 10 A rating suits branch circuits feeding lighting, socket outlets, or small motor loads. The 3 kA breaking capacity at 400 V AC covers most residential and light commercial distribution boards; verify that the prospective short-circuit current at the installation point does not exceed 3 kA.
