240A45

Description

The 240A45 is an AC-controlled Power Series relay that switches 240 VAC at up to 45 A.

Power Series relays provide 4000 volts of isolation between input and output, and offer zero-voltage turn-on and zero-current turn-off. They are UL and CSA recognized and are a CE component.

Lots of information on choosing and using SSRs can be found in the SSR data sheet. Also see the Manufacturers’ part number cross-reference list.

This SSR carries a lifetime warranty.

NOTE: We do not recommend mounting the terminal side of the SSR to a flat PCB (printed circuit board) or other flat surface, because there may be some variation in terminal height from one terminal to another and from one SSR to another. Use the MP or P series SSRs for PCB mounting.
