FAQs
The MC2C301ATWG supports DIM rail mounting on TH35-15 or TH35-7.5 profiles, enabling quick installation in standard control panels. It can also be wall-mounted in appropriate enclosures, providing flexible integration for space-constrained layouts without compromising accessibility to wiring and terminals.
For AC-3 operation at 230 V, the rated current is 12 A and at 400 V it is 12 A, with reduced current at higher voltages (up to 16 A at 690 V NO). Auxiliary circuit ratings allow 10 A, while main circuit current and voltage ratings align with IEC/EN 60947-4-1 and UL 60947-4-1 standards, ensuring reliable switching for motor loads.
Yes. Its compact 3-pole form factor, 45 mm width, 68 mm depth, and 48 mm height optimize panel space. Screw-terminal wiring and DIN-rail compatibility simplify installation in limited-access panels, while the 48 VDC coil reduces control power consumption and heat generation in dense control cabinets.
The device adheres to IEC/EN 60947-1, IEC/EN 60947-4-1, IEC/EN 60947-5-1, plus UL 60947-1, UL 60947-4-1, UL 60947-5-1. It also carries RoHS, REACH declarations, and CE/UKCA compatibility, supporting safe, compliant deployment in global manufacturing, automation, and building systems.
With mechanical durability rated at up to 10 million cycles and low coil consumption (4 W holding/pull-in), maintenance intervals extend and energy costs stay predictable. The compact footprint reduces panel real estate, while robust standards minimize regulatory risk, delivering a compelling total cost of ownership for OEMs and maintenance teams.
