FAQs
The contactor coil is rated for 50 Hz at 220-230 V and for 60 Hz at 230-240 V. This allows reliable operation with standard European and North American control circuits without additional transformers.
For AC-3 operation at 415–690 V, the unit is rated to 32 A. For AC-1 operation (broad duty) at various voltages up to 690 V, it provides up to 55 A, enabling flexible motor and load control in mixed-duty applications.
The assembly provides IP20 protection for main and auxiliary terminals, with screw terminals for secure wiring and straightforward field installation in cabinet environments.
The block contactor carries CE and UL certifications, along with CCC and CQC declarations. It also aligns with RoHS/REACH requirements, supporting compliance across European and Asia-Pacific markets.
Yes, it is compatible with front or side mounting add-on auxiliary blocks, enabling retrofit in modular cabinets. Consider space, wiring access, and torque settings (main circuit 2.3 N·m, auxiliary 1 N·m, control 1 N·m) to ensure reliable mounting and secure connections.
