• Wiring work can be shortened by as much as 60%* compared to conventional screw terminal sockets by combining with pushin 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 builtin diode and builtin CR circuit models have joined the series.
• The lineup also includes models that are compliant with the LR and VDE safety standards.
* When both pushin plus terminals and screw terminal sockets are combined with plugin terminal types (according to actual OMRON measurements as of November 2015)
