## **With Latching or Momentary Lever** 

## Latching and Momentary Lever 

Mechanical Indicator* The contact position can be confirmed through the five small windows. 

## Marking Plate 

Standard yellow marking plate is easily replaced with optional marking plates in four colors for easy identification of relays. 

## LED Indicator* 

Non-polarized green LED indicator is standard provision for plug-in terminal, latching lever types 

## **Standard (without lever)** 

Using the lever, operation can be checked without energizing the coil. The lever is color coded for AC and DC coils.

The above temperature rise curves show the characteristics when 100% the rated coil voltage is applied. The heat resistance of the coil is 120°C. The slant dashed line indicates the allowable temperature rise for the coil at different ambient temperatures. Load current 6A x 2 poles is for the RU4 models only.

Compliant Alternatives

We identify pin-to-pin, electrically equivalent substitutes that meet the same certifications (RoHS, AEC-Q100, REACH) as your original specification — validated against datasheets, not just part numbers. Often at a lower cost.
