The Schneider Electric EZC100N3020 is a 3-pole thermal-magnetic circuit breaker from the EasyPact EZC100N series, rated 20 A at 40 °C with a TM-D trip unit. It provides short-circuit and overload protection for distribution circuits in fixed-mount backplate panels. At 380 V AC the breaking capacity rises to 18 kA Icu, and at 240 V AC to 25 kA Icu, giving flexibility across common supply voltages.
The trip unit rating is 20 A at 50 °C, while the rated current [In] is listed as 20 A at 40 °C. Rated operational voltage (Ue) goes to 550 V AC and 250 V DC, covering most industrial AC supplies and DC control circuits.
Fixed mounting on a backplate — no DIN-rail adapter, so plan for screw-mounting in the panel. Connection pitch is 25 mm, which matches standard distribution-block spacing. The toggle control provides positive contact indication — you can see the mechanism position, not just a flag. IP20 finger-safe front; IK07 impact resistance handles accidental tool drops during commissioning.
Certified to EN/IEC 60947-1, EN/IEC 60947-2, JIS C8201-2-2, and GB/T 14048.2. Mechanical durability is 13,000 cycles — adequate for a distribution breaker that cycles infrequently.
