Power Relays

G7Z

331

■ Characteristics

Note: 1. The above values are initial values.

2. The contact resistance for the Relay (G7Z) was measured with 1 A at 5 VDC using the voltage drop method.

The contact resistance for the auxiliary contact block (G73Z) was measured with 0.1 A at 5 VDC using the voltage drop method.

3. The operate time was measured with the rated voltage imposed with any contact bounce ignored at the ambient temperature of 23

°C.

4. The insulation resistance was measured with a 1,000-VDC megohmmeter applied to the same places as those used for checking the

dielectric strength.

5. The electrical endurance was measured at an ambient temperature of 23

°C.

6. The specifications for the auxiliary contact block mounted on the G7Z are the same as those for the G73Z auxiliary contact block.
