FAQs
The coil is designed for 380–400 V at 50 Hz and 400–415 V at 60 Hz, matching standard European control voltages and enabling direct integration with 3-phase power systems without extra transformers.
Yes. The block contactor is rated for main circuit operation up to 690 V and AC-3 loads with currents up to 40 A depending on the voltage, making it suitable for medium-sized motors in industrial lines.
The device carries CE and UL certifications, along with RoHS compliance and related declarations, which support regulatory approvals across Europe, North America, and other regions.
Front or side-mount add-on auxiliary contact blocks are available, and the device uses screw terminals with controlled tightening torques, simplifying installation, maintenance, and future reconfigurations in existing switchgear.
Its compact footprint, modular auxiliary options, and rugged construction reduce wiring, panel space, downtime, and spare-part variety—leading to lower lifecycle costs and higher machine availability in demanding production environments.
