Recommended maximum current rating (per SSR)
1. The below recommendations are only valid when the assembly (SSR + heatsink) is mounted as shown in
the mounting instructions unless otherwise indicated.
2. The indicated ratings are applicable to one SSR, one pole. Please refer to the online selector tool at www.
productselection.net for different load currents, surrounding temperatures or multiple units on one heatsink.
3. These recommendations are applicable only with the indicated Carlo Gavazzi thermal interface material
between SSR and heatsink. In case a different thermal interface is utilised these recommendations may no
longer be valid.
