The DCNHR Series 450V High-Current High-Voltage 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 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 magnet blows the magnetic field horizontally to achieve a high-voltage DC cutoff.

The DCNHR Series contactor relay is available for 100A, 250A, and 300A contact switching.
