Specifications, Continued/Approximate Dimensions
Note: These data are non-repetitive. Keep the inrush current to half the rated value if it occurs repetitively. Inrush current resistivity is the ability of an SSR to
withstand a large surge current for a short period of time. Surges are considered non-repetitive (max. repeatability once every 2…5 seconds). Keep the inrush
current to half the rated value if it occurs repetitively. Exceeding the non-repetitive inrush current will damage the SSR.

Basic Application Considerations of Bulletin 700-SF
High Density Mounting of Multiple SSRs
If multiple SSRs are mounted side by side be aware that the outer case wall of the SSR acts as a radiator. The SSR case serves to dissipate heat. Install the
relays so that they are adequately ventilated. If poor ventilation is unavoidable, reduce the load current by half.
Connection
For DC load switching, the 700-SF SSR will operate properly if the load is connected to either the positive or negative load terminals.
Protective Component To Extend SSR Life
When controlling AC inductive loads, connect an inrush/surge absorbing device (varistor) across the SSR load terminals. If the SSR has built-in surge
suppression (Bulletins 700-SE and 700-SH) and additional surge suppression is required, connect the varistor across the terminals of the load device . Select
a varistor that meets the conditions of the load voltage outlined in the table below.

200…240V AC
380…480V AC
