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.
