Description
Bi-power Relays
LY
Power-switching Compact General-purpose Relays
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).
