New G8P
PCB Relay
Compact, Low-cost 30-A P ower Relay for
PC Board or Panel-mo unted
Applications
Compact, yet capable of switching up to 30-A
loads.
Complies with UL873 and UL508 column A
spac ing s (1 /8 through air, 1/4 over surf ace).
UL Class F insulation standard.
Withstands of up to 6,000 V under 1.250 ms
impulse wave or ring wa ve.
A selection of contact forms: SPDT and SPST-
NO.
Quick-connect terminals versions ideal for PC
board and panel mounting.
Flanged mounting available.
Ideal for home and industrial appliances, HVAC
(heating, ventilating, and air conditioning), and
many other applications.
