## **A lications pp** 

This relay is designed for use tant. It is essential that the user in applications in which it is makes sure that cooling is adexposed to high surge condiequate and that the maximum tions. Care must be taken to junction temperature of the reensure proper heatsinking lay is not exceeded. when the relay is to be used at high sustained currents. AdeIf the heatsink is placed in a quate electrical connection small closed room, control between relay terminals and panel or the like, the power cable must be ensured. 

If the heatsink is placed in a small closed room, control panel or the like, the power dissipation can cause the ambient temperature to rise. The heatsink is to be calculated on the basis of the ambient temperature and the increase in temperature.
