This is a Category B breaker — utilization class B per IEC 60947-2 — meaning it is designed for selectivity in distribution, with a deliberate short-time delay before tripping on a fault. The EVS Trip System6A electronic trip unit provides overload (long-time), instantaneous short-circuit, short-time short-circuit, and earth-fault protection. The drawout mounting (rail or base plate) allows the breaker to be racked out for maintenance without disturbing the rear-connected power cables. IP40 front-face protection suits indoor switchgear; pollution degree 4 per IEC 60664-1 means it tolerates conductive dust environments typical in heavy industrial distribution. The 25 ms maximum breaking time means the arc is quenched within two cycles at 50 Hz, limiting let-through energy for downstream equipment. Thermal memory holds a 20-minute pre- and post-trip heat profile, so a reclose after a near-trip event will not falsely trip on a cold start — important for motor or transformer feeders where inrush repeats. ## Panel integration & compliance Dimensions: 441 mm wide × 439 mm high × 395 mm deep. Rear connection with a 115 mm pole pitch (without spreader). Vertical or horizontal connection positions give flexibility in busbar layout. The digital display on the trip unit shows fault cause (overload, short-circuit, earth fault, internal fault) for rapid troubleshooting. Mechanical durability is 20,000 cycles with maintenance, 10,000 without; electrical durability is 5,000 cycles at rated voltage without maintenance — figures that govern the breaker's service life in high-cycle applications like capacitor bank switching or motor starting.","metaTitle":"Schneider EVS40H3NW6A EasyPact EVS Circuit Breaker, 4000 A,","metaDescription":"Schneider Electric EVS40H3NW6A EasyPact EVS drawout circuit breaker. 4000 A rated current, 65 kA breaking capacity at 440 V AC.
