FAQs
Begin by verifying coil voltage 230–240 V at 50/60 Hz and ensure panel space accommodates a 70 mm wide device. Mount the unit using standard 3-pole footprint, connect the three main terminals to the motor lines and tighten to 4 N·m. Wire the control circuit with 1 N·m torque on coils and validate IP20 coil terminals for protection.
For AC-1 operation at 240 V, Ie is 95 A; at 690 V this reduces to 115 A. For AC-3, ratings vary by voltage, with up to 65 A at 415–440 V and about 43 A at 690 V. The device provides up to 37 kW at higher voltages (AC-3), and a maximum breaking capacity of 1300 A cos phi 0.45 at 440 V.
Yes. The block contactor carries CE and UL/CSA certifications and declarations of conformity. It is RoHS II compliant and meets related environmental directives, including REACH and WEEE B2B classifications, making it suitable for global deployment and compliance audits across multiple regions.
The device has a 70 mm net width, 110 mm depth, and 108 mm net height. It weighs 1.01 kg and uses screw terminals for main and control connections. Its compact footprint supports easy integration into standard control cabinets and allows side mounting with accessory blocks if needed.
Ideal for controlling 3-phase motors in conveyors, pumps, fans, and general machine control. It supports AC-1 and AC-3 motor loads up to 690 V, with a coil voltage of 230–240 V at 50/60 Hz, and provides reliable switching, protective ratings, and robust mechanical life suitable for continuous, high-demand industrial environments.
