H3CR-H Specifications 10

A maximum current of 0.15 A can be switched at 125 VDC (cosφ = 1) and a maximum current of 0.1A can be switched at 125V DC and L/R = 7ms.
In both cases, a life of 100,000 operations can be expected.

The minimum applicable load is 10 mA at 5 VDC for H3CR-H8L/-HRL and 100 mA at 5 VDC for H3CR-H8RL (failure level: P).
