MCCB for distribution boards — 200 A, 3-pole, thermal-magnetic trip
The Schneider Electric EZS250E3200 is a 3-pole (3P) moulded-case circuit breaker from the EasyPact EZS range, rated 200 A at 40 °C with a thermal-magnetic TM-D trip unit. Breaking capacity is 40 kA Icu at 220/240 V AC and 25 kA Icu at 380/400 V AC, both per IEC 60947-2. At 415 V it holds 25 kA; at 440 V it derates to 20 kA. Rated insulation voltage (Ui) is 690 V, and operational voltage (Ue) is 440 V AC.
The TM-D trip unit is fixed, non-interchangeable — what you order is what protects. Long-time pickup is fixed at 1 × In (200 A), with no adjustment range. The magnetic short-circuit pickup is fixed at 2000 A (10 × In), which is a standard motor-starting tolerance but may need coordination checking against transformer inrush or high-efficiency motor starts. Protected poles are 3D (three poles protected, no neutral pole). Neutral position is left, and the connection pitch is 35 mm — standard for panel-board busbar layouts. Electrical durability is 20,000 cycles at 415 V at half rated current, and 8,000 cycles at 400 V at full rated current per GB 14048.2.
IK07 impact resistance (2 J) covers accidental tool drops during maintenance. Storage temperature range is -50 to 85 °C. Dimensions: 161 mm height × 105 mm width × 86 mm depth.
