Notes:

*1. This value can change according to the switching frequency, environmental conditions, and desired reliability level, so it is recommended to check this with the actual load.

*2. The electrical load performance value for the 20A, 80A and 120 A relay applies when a varistor is connected in parallel to the coil.

*3. Condition: Nominal switching 10 cycles, each cut-off 2,500 A

*4. The coil voltage 12 V DC type and 24 V DC type have the same specifications.

*5. at L/R ≤ 1ms
