The Schneider Electric EZC250H44200 is a 4-pole molded case circuit breaker from the EasyPact EZC250H series, rated 200 A at 40 °C with a thermal-magnetic TM-D trip unit. The TM-D trip provides both overload and short-circuit protection in a single, non-interchangeable unit — fixed-trip breakers like this are specified when the protection setting is locked at the factory and no field adjustment is needed, which suits distribution panels where the load is known and stable. The 'H' breaking capacity code means this breaker is rated for high fault levels: 85 kA Icu at 220–240 V AC, 36 kA at 380–415 V AC, and 25 kA at 440 V AC. At 550 V AC it still interrupts 10 kA.
Mounting and integration into a panel
The 140 mm width and 165 mm height fit standard distribution panel cutouts; depth is 60 mm. Connection pitch is 35 mm, matching common busbar and lug spacing for panel wiring. IP20 finger-safe protection on the front; IK07 impact resistance means it withstands a 2 J hammer blow — enough for accidental tool drops during panel work but not rated for washdown environments. Positive contact indication (red/green flag on the toggle) gives a visual confirmation of contact position independent of the handle mechanism — useful during commissioning and troubleshooting when the panel door is open.
Standards compliance covers IEC 60947-1, IEC 60947-2, GB/T 14048.2, and JIS C8201-2-2. The breaker is certified for isolation per IEC 60947-2, meaning it can be used as a disconnecting means with a visible break — important for lockout/tagout procedures on distribution feeders.
