Highlights of the New DC Contactors Available from Littelfuse

Littelfuse began offering high-voltage DC contactors for electric vehicle and alternative energy applications in the spring of 2020 when it first launched several new DCN Series contactor relays, including DCNLEV, DCNEVT, DCNEV, and DCNSEV Series products. The latest additions to the growing portfolio include the:

DCNLR Series: remote-operated contactor with a space-saving design; ideal for safely disconnecting DC energy sources in applications that require continuous run time.

DCNHR Series: high-current, high-voltage contactor with a resin body for corrosion resistance in harsh automotive environments; permanent magnet blows the magnetic field horizontally to achieve a high-voltage DC cutoff; sealed contacts for maximum safety.

DCNLB Series: normally closed high-current contactor available in single-coil and double-coil configurations; designed for electrical control systems of communication power supplies, UPS, and industrial equipment; able to make and break up to 1600 A.

DCNLM Series: high-current contactor relay for a wide variety of stationary applications, including electrical control systems for communication power supplies, industrial machines, and UPS; available with up to 400 A contact switching capability.

DCNLJ Series: contactor for high-current contact switching in electric control systems of material handling, UPS, and industrial machinery; polarized models rated for 96 V (110 V max) and non-polarized models rated for 48 V (60 V max); 125 A, 200 A, and 250 A continuous current ratings available.

DCNLH Series: magnetically latching, bistable contactor relay for high-current contact switching; designed for telecom and datacom power supplies and industrial control equipment; able to make and break up to 800 A.
