COMPACT BUT CUT OFF DC
POWER CURRENT, POWER
CAPSULE CONTACT RELAY.
EV-RELAYS
FEATURES
• Small size & light weight: size 1/4,
weight 1/2(compared to conventional
contactors)
operation noise remains unchanged
when a current of 1000A or more is inter-
rupted.
• No arc space is required: size includ-
ing arc space 1/9 (compared to con-
ventional contactors)
The arc is not exposed to the outside,
therefore, no arc space is not required.
• High contact reliability
The contact part is hermetically sealed
with H2 mixed gas, hence the contact re-
sistance remains stable regardless of the
ambient conditions.

• Safety construction
• Mounting direction is not specified
The weight of the movable parts is light,
and also the restoring force is large,
hence the contactor is relatively unaffect-
ed by gravity.
The arc is not exposed, therefore, the
contactor is explosion proof and intrinsi-
cally safe.
• Quiet: operation noise 1/4 (compared
to conventional contactors).
Along with the above-mentioned miniatur-
ization, the operation noise has been re-
duced to 70dB, and, in addition, the
• Line-up of indicator Type (150A Type
only)
A line-up of relays with indicator that can
monitor the relay operation.
