Voltage Rating:3.5kV
Current Rating:18A
Contact Form:C = Single Pole Double Throw
Contact Arrangement:SPDT
Application:Make/Break Load Switching
RH3 series high voltage relays are a variant of the RH1, featuring the same ultra-compact capsule style form factor and 3.5kV voltage rating but with molybdenum/tungsten contacts for enhanced make and break load switching. While the RH3 series offers improved performance in switching, it has a higher contact resistance compared to the RH1, resulting in a reduced 18 amp continuous current carry rating. The Single Pole Double Throw (SPDT) configuration provides design flexibility by incorporating both Normally Open (NO) and Normally Closed (NC) contact sets within a single relay. Continuity transfers between the contact sets when the coil is powered on or off.
