FAQs
Yes. The unit uses the same block-contactor form factor with 3 main NO contacts and one NO plus one NC auxiliary contact. It supports side-mount add-on auxiliary blocks and is designed for fast wiring via screw terminals, enabling seamless integration with AX50–AX80 components.
Coil voltage is 50 Hz 220–230 V or 60 Hz 230–240 V. AC-1 rated current is up to 95 A at 230 V and up to 115 A at 690 V (40 °C). AC-3 ratings reach 65 A in multiple voltages (e.g., 380–440 V) or 43 A at 690 V, with a rated power up to 37 kW at 415–690 V.
Ideal for starting and stopping 3-phase motors in conveyors, pumps, packaging lines, and general machinery. Its 125 A I_th and 37 kW peak power capability support mid-range motor control while preserving drive efficiency and allowing compact panels.
The block contactor carries CE and UL certifications, plus CCC and CQC declarations, with 690 V insulation, RoHS compliance, and WEEE B2B suitability, ensuring broad regulatory acceptance in EU and NA markets.
Low power loss per pole (6.5 W AC-1, 1.5 W AC-3) reduces heat, while robust mechanical design supports high cycling frequency. Its compact size and accessories simplify installation, spare parts management, and future motor-control upgrades, delivering faster ROI.
