FAQs
The MC2C310ATWJ supports on-DIN-rail mounting using TH35-15 or TH35-7.5 rails and is equipped with screw terminals for main, auxiliary, and control circuits. Wire termination is designed for flexible and rigid conductors within the specified cross-sections, with a recommended tightening torque of 0.8 to 1.0 N·m to ensure reliable connections and vibration resistance in industrial environments.
Main circuit provides 3 normally open main contacts with a 20 A rated operational current at up to 690 V auxiliary circuits; auxiliary circuit includes 1 normally open contact. Rated operational power for AC-3 is 3 kW at 230 V, 5.5 kW at 400 V, and 5.5 kW at 500 V, while DC ratings support 110 V coil control with appropriate DC continuous operation parameters.
Yes. The device is a three-pole mini contactor designed for AC-3 and DC control scenarios, suitable for motor-start and load switching in commercial buildings and light industrial equipment. Its 20 A Ie rating at common voltages, compact footprint, and DIN-rail mounting simplify panel design, improve efficiency, and support reliable motor control in space-constrained assemblies.
The MC2C310ATWJ carries CE and UKCA declarations, UL/UL CSA certifications, and additional approvals such as CB, BV, CQC, CCC, and CCC, along with RoHS and REACH compliance. This broad certification set enables global deployment across Europe, North America, and other regions, reducing the need for re-qualifications on multinational projects.
With a mechanical durability rating of 10 million cycles and low coil power consumption (4 W holding, 4 W pull-in for DC operation), the MC2C310ATWJ minimizes maintenance and energy usage. Its robust IP20 terminal protection, screw-terminal design, and reliable screw connections reduce downtime and extend service life in demanding environments.
