Hartland Controls / Littelfuse HCR-5 SPNO & SPDT General Purpose Switching Relays
Hartland Controls / Littelfuse HCR-5 SPNO and SPDT General Purpose Switching Relays are available in SPNO, SPDT, and one normally open (NO) and one normally closed (NC) switching configurations. These relays feature a double-make contact configuration, 0.250″ QC power pole and coil terminations, Class B insulation system, and silver cadmium oxide contacts. The relays control circuits through a low-power signal. An electromagnetic current actuates the relay, creating a closed circuit within the device. These multi-positional mount relays are in-house tested and validated. Hartland Controls / Littelfuse HCR-5 SPNO and SPDT General Purpose Switching Relays are used in applications such as HVAC systems, standby power supplies, and telephone exchanges.Features
