## G9EB-1 DC Power Relays (25-A Models) 

## **DC Power Relays Capable of Interrupting** 

## **High-voltage, High-current DC Load** 

- Utilizes a unique gas-filled, fully sealed, non-ceramic construction achieved by using resin with a metal case. This reduces the need for special processing and materials that were required with previous models, resulting in a low-cost relay that is both compact and lightweight. 

- Smallest and lightest in its class at 25 × 60 × 58 mm and approximately 135 g. This is approximately half the volume and a third of the weight of other DC Power Relays in the same class (400 VDC, 25 A).* 

- The unique design of the contact switching component and permanent magnet for blowing out the arc eliminates the need for polarity in the main circuit (contact terminal). This improves ease of wiring and installation, and contributes to providing failsafe measures against incorrect wiring. 

* Based on our investigation as of December 2004.

Note. The above values are initial values at an ambient temperature of 23°C unless otherwise specified. 

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

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

*3. The impulse withstand voltage was measured with a JEC-212 (1981) standard impulse voltage waveform (1.2 × 50 μ s). 

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

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

*6. These values are for when a varistor is used as the protective circuit against reverse surge in the relay coil. Using a diode will reduce theswitching characteristics.
