Electromechanical Relays LY
• Wiring work can be shortened by as much as 60%* compared to conventional screw terminal sockets by combining with push-in plus terminal sockets (PYF- -PU) that feature light insertion force and strong pullout strength to achieve less wiring work • The standard models include models that are compliant with the UL, CSA, and SEV safety standards and with the Electrical Appliances and Material Safety Act • Equipped with an arc barrier for arc interruption • Withstand voltages up to 2,000 V • New built-in diode and built-in CR circuit models have joined the series • The lineup also includes models that are compliant with the LR and VDE safety standards
