General Purpose Relay
LY
• Arc barrier equipped.
• High dielectric strength (2,000 VAC).
• Long dependable service life assured by Ag-Alloy contacts.
• Choose models with single or bifurcated contacts,
LED indicator, diode surge suppression,
push-to-test button, or RC circuit.
• UL, CSA, and TUV approvals on all standard LY Relays.
• CE marks included on non-PCB mount versions.
Ordering Information
