The G3N series of solid state relays are used
to control large resistance heaters in
conjunction with temperature controllers.
Solid state relays are SPST, normally open
switching devices with no moving parts,
capable of millions of hours of operation.
By applying a control signal, an SSR
switches ON the AC (or DC) load current,
just as the moving contacts do on a
mechanical relay. Three-phase loads can be
controlled using 2 or 3 SSR’s. Use 3 SSR’s
for Y or star 3-phase loads using a neutral
line. Two SSR’s will control “delta” loads
with no neutral line. Three solid state relays
are also used when there is no neutral load
to provide redundancy and extra assurance
of control.

“Switching” takes place at the zero voltage
crossover point of the alternating current
cycle. Because of this, no appreciable
electrical noise is generated, making SSR’s
ideal for environments where there are
apparatuses susceptible to RFI.

Y92B-N150 Heat Sink for the G3NA-240B, G3NA-440B, G3NE-625B.

For surface mounting, a 30% derating of the load current is required (from the Load Current vs. Ambient Temperature graphs).
The orientation indicated by the external dimensions is not the correct mounting orientation. When opening mounting holes, refer
to the mounting hole dimensions. If using Y92B-N150 as heat sink for relay, maximum recommended current is 25 A.

Y92B-N100 Heat Sink for the G3NA-220B, G3NA-420B, G3NE-220T(L).

For surface mounting, a 30% derating of the load current is required (from the Load Current vs. Ambient Temperature graphs).
The orientation indicated by the external dimensions is not the correct mounting orientation. When opening mounting holes,
refer to the mounting hole dimensions.

Y92B-N50 Heat Sink for the G3NA-205B, G3NA-210B, G3NA-D210B, G3NE-210T(L).

For surface mounting, a 30% derating of the load current is required (from the load current vs. ambient temperature graphs).
The orientation indicated by the external dimensions is not the correct mounting orientation. When opening mounting holes,
refer to the mounting holes dimensions.
