Specification Summary for Procurement Verification
The Schneider Electric EZC250H44175 is a 4-pole molded case circuit breaker from the EasyPact EZC250H series, rated at 175 A at 40 °C ambient. The thermal-magnetic TM-D trip unit provides overload and short-circuit protection. Breaking capacity is 85 kA Icu at 220–240 V AC, 36 kA at 380–415 V AC, and 25 kA at 440 V AC, all per IEC 60947-2. For DC circuits, it delivers 30 kA Icu at 125 V DC (1P) and 30 kA at 250 V DC (2P).
Standards Compliance and Environmental Ratings
The breaker complies with EN/IEC 60947-2, JIS C8201-2-2, and GB/T 14048.2. It carries an IP20 degree of protection per IEC 60529 and IK07 impact resistance per EN 50102.
Mounting and Connection Details
The EZC250H44175 is a fixed-mount breaker with backplate support. Both line and load connections are front-facing. Connection pitch is 35 mm. Dimensions: width 140 mm, height 165 mm, depth 60 mm. The toggle control provides positive contact indication.
Application Context and Selectivity Considerations
The breaker is classified as Category A, meaning it is not intended for current-limiting applications requiring Category B performance. Mechanical durability is 10,000 cycles.
