FEATURES

• Control of large voltages and

currents

The relays have a sealed construction

that is filled with a hydrogen gas

compound, and use a permanent magnet

to establish a magnetic path for the arc.

This allows them to switch high-level DC

voltages of up to 400V DC.

• Compact size and light weight

The capsule contact construction is filled

with a gas that has excellent thermal

dissipation and insulation characteristics.

Because of this we have been able to

reduce the contact gap to one tenth that

of conventional relays, and produce a

compact and light design.

• 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,

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 types (150A Type

only)

1 Form A and 1 Form B types with

indicators for detecting welding of the

main contacts are available.

• Line-up of PC board type and TM

type (10A type only)

• 12 and 24V DC coil voltage types are

available.

• Screw terminal blocks for easy

wiring.
