DCNHR

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 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
