The DVoltage  
DC Contactor Relay is a normally open (also known  
as monostable) relay with a resin body for corrosion  
resistance in harsh automotive environments. Versions  
are available with a pulse width modulation (PWM) coil  
to reduce power for keeping the contacts closed. Sealed  
contacts help ensure there is no leakage of electrical arc  
for safety. The high-current relay’s permanent magnets  
blow out the magnetic field horizontally to achieve a rapid  
extinguishing of the DC arc.  
Features and Benefits  
• Available with 20A to 300A contact switching capability  
• Normally open relay design  
• Resin housing provides corrosion resistance in harsh  
automotive environments  
• Sealed contacts with no leakage of electrical arc for  
maximum safety  
• Built-in energy-saving coil to reduce the coil holding power  
consumption  
The DCNHR Series contactor relay is available for 20 A  
to 300 A contact switching as well as with and without  
polarized contacts to suit the polarity of your application.  
• RoHS compliant  
• Available with mechanically linked auxiliary contacts
