RU
Electrical Life Curves
• • • • RU4 (Resistive Load)
• • • • RU42 (Resistive Load)
Maximum Switching Current
• • • • RU4 (Rated Load)
Ambient Temperature vs. Temperature Rise Curves
• • • • RU4/RU42 (AC Coil, 50 Hz)

The above temperature rise curves show the characteristics when 100% the rated coil voltage is applied.
Load current 6A × 2 poles is for the RU4 types only.
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.
