EV (AEV)
Capsule contact 
mechanism and 
EV RELAYS (AEV)
high-capacity cut-off 
compact relay
FEATURES TYPICAL APPLICATIONS
1. Compact and lightweight High DC voltage applications such as
Charged with hydrogen gas for high arc  Electric vehicle
cooling capacity, short gap cutoff has  Hybrid vehicle
been achieved at high DC voltages.  Fuel-cell vehicle
2. Safety  Battery charge and discharge 
High safety achieved with construction systems
10A 20A
that prevents explosions by keeping the  Construction equipment
arc from leaking.
3. High contact reliability
Since the contact portion is sealed in 
hydrogen gas, there is no contact 
oxidation. The relay is also dustproof.
