More info

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. Single-pole and double-pole models have AC4 ratings and DC2 ratings (operating coil ratings: 100/110 VAC, 110/120 VAC, 200/220 VAC, 220/240 VAC, and 100/110 VDC). Three-pole and four-pole models have AC4 ratings and DC2 ratings (operating coil ratings: 100/110 VAC, 200/220 VAC and 100/110 VDC).

Note: 1. Cells with a diagonal line cannot be manufactured. Ask your OMRON representative for details on manufacturing
              products for cells containing "---" in the above table.
           2. If #187 tab terminals are required, use the LY1F-T2 or LY2F-T2 (single-pole or double-pole models only).
           3. Refer to Catalog for information on plug-in terminal and socket combinations.
           4. Items with an asterisk (*) in the table are certified for UL, CSA, and SEV. This is indicated with a certification
                 mark on the products.
           5. Items with two asterisks (**) in the table are certified for UL and CSA. This is indicated with a certification mark
                on the products.
           6. All models in the table are certified for IEC (TÜV).
           7. The models with plug-in terminals (single-pole, double-pole, and 4-pole) were combined with the PTF-E for the
                 EC Declaration of Conformity. These products display the CE Marking.
