FEATURES

• Small size & light weight: size 1/4,
weight 1/2(compared to conventional
contactors)

• No arc space is required: size includ­ing arc space 1/9 (compared to con­ventional contactors)

The arc is not exposed to the outside,
therefore, no arc space is not required.

• Safety construction

The arc is not exposed, therefore, the
contactor is explosion proof and intrinsi­cally safe.

• Quiet: operation noise 1/4 (compared
to conventional contactors).

Along with the above-mentioned miniatur­ization, the operation noise has been re­duced to 70dB, and, in addition, the

operation noise remains unchanged
when a current of 1000A or more is inter­rupted.

• High contact reliability

The contact part is hermetically sealed
with H

2

mixed gas, hence the contact re­sistance remains stable regardless of the
ambient conditions.

• 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 unaffect­ed by gravity.

• Line-up of indicator Type (150A Type
only)

A line-up of relays with indicator that can
monitor the relay operation.
