The Schneider Electric EasyPact EVS08H4MW6A is a 4-pole drawout circuit breaker rated 800 A at 40 °C, with an electronic trip unit (EVS Trip System6A) that covers overload (long-time), instantaneous short-circuit, short-time short-circuit, and earth-fault protection. Its 65 kA Icu at 220...440 V AC (50/60 Hz) per IEC 60947-2 means it can safely interrupt fault currents up to that level without upstream cascading — critical for high-fault-capacity distribution panels. Category B utilisation means it is designed for selectivity with downstream devices, not just cable protection. The drawout mounting and rear connection suit switchgear assemblies where the breaker must be racked out for maintenance without de-energising the bus. The digital display on the trip unit gives local readout of fault type (internal fault, overload, short-circuit, earth fault) and thermal memory status — the 20-minute thermal memory before and after tripping means the breaker remembers its thermal state even after a trip, preventing immediate reclose on a still-hot conductor.
The EVS08H4MW6A is listed as current-production (lifecycle stage: current). No official successor has been assigned — this is the active variant in the EasyPact EVS range.
Mounts on a rail or base plate in a drawout configuration — typical for metal-enclosed low-voltage switchgear (MCC or distribution board). The 556 mm width, 439 mm height, and 395 mm depth define the cell cutout; connection pitch is 115 mm without spreader. Neutral is on the left. Vertical or horizontal connection positions allow top-feed or bottom-feed bus arrangements.
