The 3 main poles with a single auxiliary NO/NC contact block deliver straightforward motor control for 3-phase loads, enabling reliable switching with minimal wiring complexity and a clear path to scalable automation. This directly improves downtime when changing configurations and reduces wiring errors during installation, especially in high‑volume environments where standardization matters. The coil voltage options of 400–415 V at 50 Hz and 415–440 V at 60 Hz simplify worldwide sourcing, cutting regional variants and stock needs. The contactor supports AC‑3 and AC‑1 operation up to 690 V, enabling efficient starting of large motors while meeting international standards for protection and energy use. Its compact block design with 82 mm net width and 108 mm height fits tighter control panels, reducing cabinet depth. Energy losses are minimized with 5 W per pole in AC‑1 and 1.3 W per pole in AC‑3, contributing to lower running costs over the motor’s life. Optional auxiliary blocks allow side mounting and customization for complex control logic, reducing the total number of separate components in the panel. Compliance with RoHS, REACH, WEEE, and UL/CSA frameworks reinforces safe, long‑term asset management and regulatory alignment for OEMs and end users alike.

FAQs
This 3-pole block contactor fits standard control cabinet layouts with a compact footprint (82 mm net width, 110 mm depth, 108 mm height) and screw terminals for secure wiring. It supports optional auxiliary contact blocks for side mounting, enabling expanded control logic without adding extra devices. Ensure panel openings accommodate the 690 V main circuit isolation and coil connections, and plan for IP20 coil terminals and IP10 main terminals to meet typical panel protection requirements.
For AC-1 operation, the device provides up to 100 A at 690 V (35–85 A depending on voltage and ambient temp), and AC-3 ratings show up to 53 A at 440–690 V with 55 °C ambient. Short-time withstand and breaking capacities are specified (Icw up to 1000 A for brief durations, with cos φ considerations). These ratings support starting and running of standard motors in typical industrial loads while maintaining safe margins for overload conditions.
Yes. The 3 NO main contacts plus 1 NO/1 NC auxiliary contact configuration is well suited for motor control in conveyors and pump systems. Its AC-3 rating aligns with motor starting and running, while the 690 V insulation voltage supports modern drives. The compact form factor and accessible auxiliary contact options simplify integration into automation schemes and panel layouts common in material handling and pumping applications.
The contactor is documented with CE conformity and UL/CSA certifications, along with RoHS and REACH declarations, plus a CCC certificate for broader markets. This combination supports regulatory compliance across regions, reduces risk during audits, and helps streamline procurement for multinational projects while ensuring safe disposal and material reporting practices.
Maintenance advantages include modular auxiliary blocks for easier upgrades and reduced cabinet rework, and robust terminals that support dependable field connections. Energy efficiency is reflected in low per‑pole power loss (5 W AC‑1, 1.3 W AC‑3), translating into lower operating costs over the motor’s lifetime. The compact footprint also reduces cabinet space, contributing to lower enclosure costs and simpler spare‑part stock management, improving total cost of ownership.
