FAQs
This 3-pole block contactor is designed for three-phase motors up to 690 V and supports a 110 V control circuit at 50/60 Hz. It uses screw terminals for main and control connections and is compatible with add-on auxiliary contact blocks for extended control, making it suitable for standard industrial motor control panels.
Rated Operational Current AC-3 is up to 80 A at 415–690 V and 46–80 A depending on voltage, with a maximum breaking capacity of 1300 A at 440 V and 630 A at 690 V (cos phi 0.45). For AC-1, Ie can reach 125 A at 690 V, enabling robust motor starting and protection in demanding applications.
Yes. It is specified for ambient temperatures from -25 to 70 °C with appropriate mounting conditions, and coil terminals are protected with IP20 while main terminals are IP10. This makes it suitable for factory floors, panels, and automation installations where reliability and environmental tolerance are important.
The device is CE-, UL-, and RoHS-compliant, with supporting declarations and CB/CQC certifications. These certifications ensure global regulatory acceptance, safe installation, and reduced compliance risk for traceability in automotive, machinery, and industrial equipment applications.
Low power loss per pole (7 W AC-1, 2 W AC-3) reduces heat within panels, lowering cooling needs and energy costs. The compact footprint and screw-terminal wiring simplify installation, spare-part management, and future upgrades, contributing to minimized downtime and faster ROI in ongoing motor-control projects.
