Features

1.High-voltage, high-current control capable

1,000V DC switching has been achieved thanks to a sealed construction with mixed hydrogen gas and the magnetic arc motion through use of a permanent magnet.

2.Compact & Low Operating Sound

By using a capsule contact mechanism that is enclosed with hydrogen gas, highcapacity cutoff is possible even with a tiny contact gap. There is little operating sound, which does not change even when large currents are cut off.

3.Arc space unnecessary

The enclosure box can be made smaller thanks to an arc-space-free construction from which the arc will not get out.

4.Safety

Since the contacts are enclosed in a sealed capsule structure, the arc will not get out, which ensures safety.

5.High contact reliability

The contact part is hermetically sealed with H2 mixed gas, hence the contact resistance remains stable regardless of the ambient conditions.

6.Mounting direction is not specified

The weight of the movable parts is light, and also the restoring force is large, hence the relay is relatively unaffected by gravity.

7.Wide selection of models available.

Types include PC board type (10A), TM type (10A and 20A), Lead wire type (200A) and Connector type (80A and 300A).

8.Standard compliance

The 10A, 20A, 80A type is UL/C-UL standard certified.

Typical Applications

1.Photovoltaic power generation systems

2.Cogeneration systems

3.Construction machinery

4.Welding equipment

5.Battery charge and discharge control

6.AGV (Automatic guided vehicle) (Unmanned transport carts)

7.Inverter control

8.Elevator, etc.
