Key features & benefits

EVpack-fuse line-up belongs to Mersen’s DC Over-Current protection (O.C.P.) portfolio specifically developed to address on-board electric and hybrid vehicles applications.
EVpack-fuse provides the ultimate protection by offering reliable clearing of DC fault currents in challenging environments and complies with the high-quality requirements of the automotive industry.
The MEV55C has specifically engineered and tested to provide best-in-class protection performance for auxiliary circuits: Up to 550VDC, Current rating (In)= 5 to 50A, Interrupting Rating (IR) = 20kA,L/R ≤1ms, Minimum Breaking Capacity (MBC) as low as 2xIn for a perfect matching with cable protection.
The MEV50A has been specifically engineered and tested to provide best-in-class protection performance for main battery and on-board charging protection: Up to 500VDC, Current rating (In)= 60 to 800A, Interrupting Rating (IR) = 30kA, L/R ≤ 2.5ms, Minimum Breaking Capacity (MBC) as low as 2xIn or a perfect matching with DC contactor.
