Model no: OMRON G3PB-515B-3N-VD
Load: 3-Phase* 15amp [AC-51 rating] [load votage range 200...480V 50/60Hz]
[*switches all three poles simultaneously.]
Prefitted with compact vented alumium heatsink and heavy duty din rail/panel mounting bracket. [fits to standard 35mm "consumer unit" style din rail or can be panel mounted with four screws.]
Other features: Zero-cross switching. [This zero cross-firing feature eliminates problems of transmitted RFI/EMI] Operation indicator led. Clip-on teminal cover.

Basic Installation Guidelines: The module will need to be mounted in an enclosure where there cannot be accidental contact with the exposed high-voltage terminals.
Thermal management is critical. The module relies on convection of cool air through the heatsink for cooling. The unit will need to be mounted in an enclosure with good ventilation for cooling purposes. It may be necessary to install an equipment fan or extractor on the enclosure. I can usually supply 120mm equipment fans at a bargain price. Just ask.
The SSR must NOT be exposed to short circuit of the output.
