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.

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.

Approximate Dimensions

All units are in millimeters unless otherwise indicated. Dimensions are not intended for manufacturing purposes.

Note: The 700-SF is compatible with the 700-HN116 socket.

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.
