FAQs
The unit uses a 24 V control circuit and 50/60 Hz. It employs screw terminals for reliable electrical connections, enabling straightforward integration with common PLCs and soft starters. Optional auxiliary contact blocks can simplify wiring schemes and provide additional feedback signals for automation sequences.
Rated Operational Current AC-1 (Ie) includes values around 85–100 A depending on voltage and ambient temperature (e.g., 690 V at 40 °C). AC-3 ratings vary by voltage (e.g., ~35–53 A). Short-time withstand current (Icw) is specified up to 1000 A for short pulses, supporting safe motor starting and fault tolerance in free-air conditions.
Yes. With 3 main NO contacts, 690 V insulation, and 3-pole configuration, it is designed for 3-phase motor control in heavy-duty applications such as conveyors, pumps, and packaging lines. Its robust mechanical design and accessory compatibility improve reliability and reduce maintenance downtime.
The device carries CE conformity, UL/CSA recognition, CCC, CQC, and RoHS compliance. This suite supports global deployments, supplier qualification, and regulatory adherence across North America, the EU, and Asia-Pacific regions.
The screw-terminal design, compact footprint, and standard accessories streamline installation and servicing. The integrated coil protection and high breakdown capacity reduce ancillary components, while the compact size minimizes enclosure space and installation time, yielding faster project completion and lower total cost of ownership.
