General-purpose Relay
LY
A Miniature Power Relay
• Equipped with arc barrier.
• Dielectric strength: 2,000 V.
• Built-in diode models added to the LY Series.
• Single-pole and double-pole models are applicable to operating
coils with ratings of 100/110 VAC, 110/120 VAC, 200/220 VAC,
220/240 VAC, or 100/110 VDC).
• Three-pole and four-pole models are applicable to operating
coils with ratings of 100/110 VAC, 200/220 VAC, or 100/110
VDC).
