The CR1F500R7: Rated operational current [Ie] is 500 A, with a rated operational voltage [Ue] of 1000 V AC. Motor power reaches 335 kW at 690 V AC, 295 kW at 440 V, and 250 kW at 400 V. For UL/CSA installations, motor power is 500 hp at 575 V and 400 hp at 480 V. Control circuit voltage is 440 V AC 50/60 Hz, with latching and unlatching limits of 0.85 to 1.1 Uc. Average coil consumption is 1800 VA for latching and 13 VA for unlatching, both AC and DC.
The 500 A rated operational current in AC-3 duty means this contactor handles heavy motor starting loads — the AC-3 category covers squirrel-cage motors during starting and switching off running motors. The AC-1 rating covers resistive loads at the same current level. Rated breaking capacity is 5000 A at 220-440 V, 4500 A at 500 V, and 2500 A at 1000 V. The rated short-time withstand current [Icw] is 4200 A for 1 second, giving selectivity headroom for fuse or breaker coordination. This is a heavy-duty industrial contactor, not a high-speed switching device — it is built for infrequent but reliable latching operations in motor control centers or large machinery.
Mounts on a notched AM1-EC rail, which is a heavy-duty DIN rail variant for large contactors. Dimensions are 238 mm height, 233 mm width, and 232 mm depth — substantial footprint requiring panel space planning. Connections are via lugs-ring terminals (2 cables of 240 mm²) or bars (2 cables, busbar cross-section 40 x 5 mm). Tightening torque is 35 N.m. This is a panel-mount component, not for washdown environments.
Compliant with IEC 60947-4 (low-voltage switchgear and controlgear for motor starters), VDE 0660, JEM 1038, NF C 63-110, and BS 5424. Rated insulation voltage [Ui] is 1000 V per IEC 60947-4 and BS 775, 1500 V per VDE 0110 Group C. Impulse withstand voltage [Uimp] is 8 kV. Associated fuse ratings for the power circuit are 500 A aM, 800 A BS88, or 800 A gG at ≤440 V. Power dissipation per pole is 45 W in AC-3 and 88 W in AC-1 — factor this into enclosure thermal calculations. Average impedance is 0.18 mOhm at Ith 700 A 50 Hz.
