DC Power Relays (60-A, 100-A Models)

G9EA-1

Specifications

■ Ratings

Coil

Note: 1. The figures for the rated current and coil resistance are for a coil temperature of 23

°C and have a tolerance of ±10%.

2. The figures for the operating characteristics are for a coil temperature of 23

°C.

3. The figure for the maximum voltage is the maximum voltage that can be applied to the relay coil for period of 10 minutes at an ambient

temperature of 23

°C. It does not apply to continuous operation.

Contacts

■ Characteristics

Note: 1. The above values are initial values at an ambient temperature of 23

°C unless otherwise specified.

2. The contact resistance was measured with 1 A at 5 VDC using the voltage drop method.

3. The insulation resistance was measured with a 500-VDC megohmmeter.

4. The impulse withstand voltage was measured with a JEC-212 (1981) standard impulse voltage waveform (1.2

× 50 μs).

5. The mechanical endurance was measured at a switching frequency of 3,600 operations/hr.

6. The electrical endurance was measured at a switching frequency of 60 operations/hr.
