That AC-3 category (per IEC 60947-4) covers starting and stopping squirrel-cage motors — the most common industrial motor load. The 500 A rated operational current in AC-3 tells you the continuous current it can handle while switching motor inrush. For resistive loads (AC-1), the contactor handles heating and lighting circuits without the inductive kick that stresses the contacts. The coil dropout range is 0.5 to 0.7 Uc at 50 Hz. Breaking capacity is specified at 3800 A at 3700 A at 500 V, 3600 A at 660/690 V, and 2600 A at 1000 V, all conforming to IEC 60947-4-1. The associated fuse recommendation is 315 A aM or 400 A gG at ≤ 400 V for the control circuit. This contactor is designed for panel-mount installation in motor control centers or standalone enclosures. The power circuit uses bolted connections accepting cable with lug up to 185 mm²; control circuit terminals accept 1 to 6 mm² solid or stranded wire with a tightening torque of 1.2 N·m. The maximum operating rate is 120 cycles per minute at 55 °C — useful for high-duty-cycle applications like compressor cycling or conveyor indexing. Power dissipation per pole runs 63 W in AC-3 and 75 W in AC-1, so panel ventilation or derating may be needed in tightly packed enclosures. The contactor carries 2 NO + 2 NC instantaneous auxiliary contacts built in, which is enough for basic feedback and interlocking without an add-on block. For applications requiring more auxiliaries or timed contacts, the TeSys B range supports add-on auxiliary contact blocks that snap onto the front. The contactor complies with IEC 60947-4 and EN 60947-4 standards for low-voltage switchgear and motor starters. ## What the standards tell you IEC 60947-4 is the governing standard for contactors and motor-starters. It defines the AC-1 (resistive) and AC-3 (motor) utilization categories, the rated operational current Ie, the making and breaking capacities, and the short-time withstand current Icw. The CV3BK3V0ZM522's Icw is 4000 A for 1 second at 40 °C, which tells you the contactor can withstand a short-circuit current for that duration while the upstream protective device clears the fault.","metaTitle":"Schneider Electric CV3BK3V0ZM522 TeSys B Contactor, 250 kW A","metaDescription":"Schneider Electric TeSys B contactor CV3BK3V0ZM522. 250 kW at 400 V AC (AC-3), 500 A rated operational current. 3-pole, 220 V AC 50 Hz coil.
