Question

Can 4-pole LY4 General-purpose Relays switch 10 A?

Answer

The contact ratings per pole are described below.

For example, for a 110-VAC or 24-VDC Relays are used with a resistive load, the contacts can switch 10 A, but if the load is inductive, a 110-VAC Relays can switch only 7.5 A, and a 24-VDC Relays, only 5 A (not 10 A).
