Characteristics

Note. The values given above are initial values at 23°C. (Except Electrical Durability)

*1.

Measurement conditions: 200 A at 6 VDC (after 30 minutes) voltage drop method.

*2.

Measurement conditions: Applied rated coil voltage, no contact bouncing.

*3.

Measurement conditions: Measured with a 1,000 VDC megohmmeter at the same point as the dielectric strength was measured.

*4.

This specification is when diode and zener diode are used. For relay coil, please connect diode and zener diode.

For more detail, please refer to

Diode Connection for Operating Coil on page 6.

*5.

The value was measured at a switching frequency of 180 operations/ minute.

*6.

For the detail regarding holding voltage usage, please refer to

Coil Voltage Reduction (holding voltage) after Relay Operation on page 6.
