Note: 1. When switching DC inductive loads at 125 V or more, an unstable region exists for a switching current of between
0.5 and 2.5 A. The Relay will not turn OFF in this region. Use a switching 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.
*1. Refer to Switching an Switching an AC Load with a DC-switching Model (“X” Model) on Data Sheet.
