*Increase AC current values by 25% for mounting style 2 with single switch.

Must-Operate Voltage: 
  DC: 75% of nominal voltage @ +25C.
  AC: 85% of nominal voltage @ +25C.
Operating Position:  Relay is designed for operation with plunger either
                     vertical or horizontal: however, the relay is not 
                     designed for operation in an upside-down position.

Temperature Range: -10C to +65C
