Description
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.

Applications
• Battery electric vehicles
