increases by approx. 10 mA due to the current consumption of the LED. The rated current of a model with a

Note: 1. When switching DC inductive loads at 125 V or more, an unstable region exists for a contact current of between
0.5 and 2.5 A. The Relay will not turn OFF in this region. Use a contact current of 0.5 A or less when switching
125 VDC or more.
2. If L/R exceeds 7 ms when switching DC inductive loads, an arc-breaking time of up to 50 ms must be considered
in application and the circuit must be designed to ensure that an arc-breaking time of 50 ms is not exceeded.
3. The switching capacity for an AC load is minute.
*1. Refer to Switching an AC Load with a DC-switching Model ("X" Model) on Data Sheet.
*2. This value is measured at 60 operations/min.

between 0.5 and 2.5 A at a minimum of 125 VDC, where the load cannot be switched.
2. If L/R exceeds 7 ms when switching DC inductive loads, an arc-breaking time of up to 50 ms must be considered
