DCN High-Current High-Voltage DC Contactor Relays

Littelfuse DCN High-Current High-Voltage DC Contactor Relays enable design engineers to incorporate high-voltage relay switching into various high-current and high-voltage applications. These DCN contactor relays offer 30A to 500A continuous carry and up to 1800V voltage rating. The magnetic arc blowout design dissipates any arc between the contacts within a sealed, gas-filled arc chamber. The coil economizer feature greatly reduces coil power and heating with signal pulse width modulation. Typical applications for these Littelfuse relays include electric vehicles (EVs), charging stations for EVs and hybrid electric vehicles (HEVs), electric forklifts, and more.
