It carries a TM-D trip unit — fixed thermal and magnetic settings, no adjustments — so it's a straight swap-in for a line that's already coordinated. The breaking capacity hits 30 kA Icu at 400 V AC 50/60 Hz per IEC 60947-2, which covers most industrial panel SCCR requirements without stepping up to a higher frame.
At 240 V AC it jumps to 50 kA Icu, and at 125 V DC single-pole it's 10 kA. The 4-pole version (EZC100H4050) protects three phases with a solid-neutral pass-through — no neutral protection, so it's meant for three-phase loads where the neutral carries only imbalance current. IP20 means finger-safe but not sealed — mount it inside a panel with at least an IP54 enclosure if there's washdown or dust.
Fixed backplate mounting — no DIN-rail clip on this frame. You bolt it to a mounting plate in the enclosure. Connection pitch is 25 mm, front-connected both line and load sides. Toggle handle gives positive contact indication, so you can visually confirm the contacts are open or closed without a meter. It's a Category A breaker (no intentional short-time delay), so coordination with downstream breakers relies on the instantaneous trip characteristic.
