During normal operation, the current flows through the positive and negative contacts, the control contact is isolated in this position. If the connector is disconnected, the following steps are performed inside the connector.
1) The positive contact is designed to be slightly shorter than the negative contact. This means, it is disconnected first during the disconnection process.
2) At the same time, the control contact is routed from the isolated area to the conductive area. From this moment on, the current flows through the electronics that reliably opens the circuit.
3) The circuit is open and current is no longer flowing. In the next step of the disconnection process, the control contact and negative contact disconnect without arcing. PE is designed as a leading contact so that it is disconnected last.
How robust is the male connector?
The connector is resistant to impacts of class IK08 at temperatures up to -25°C. The impact force is similar to the impact of a medium-sized hammer dropping from a height of approximately 1 m onto the connector.
Why is the male connector so large?
Using the ArcZero connector, end and distribution circuits up to 20 A and 400 V or 800 V can be connected. To be able to safely disconnect 400 V or 800 V under load, large clearances between the potentials are required inside the connector. The clear... View more
Using the ArcZero connector, end and distribution circuits up to 20 A and 400 V or 800 V can be connected. To be able to safely disconnect 400 V or 800 V under load, large clearances between the potentials are required inside the connector. The clearances prevent the operator from suffering an electric shock.
View lessDo I need to support the male connector mechanically?
Yes, mechanical loads, e.g., due to cables, need to be supported up to 50 cm behind the connector, e.g., through cable ties. The bending radius of the cable must also be observed.
Is the male connector suitable for outdoor use?
Yes, the ArcZero connectors are made of the same materials that we use in our photovoltaic connectors. They are therefore designed for long-term use outdoors. To test the interaction of the materials for outdoor use, the ArcZero connectors undergo th... View more

The cable must always meet the requirements of your application. Therefore, check the cable data sheet to determine whether the cable manufacturer has approved the cable for the desired application. When selecting cables, pay special attention to the DC voltage level and whether it is suitable for indoor or outdoor use.

A female contact or pin contact appears to be darker or sooty compared to the other contacts. What does that mean?
This is quite normal. The shutdown electronics safely extinguishes the electric arc. However, an initial electric arc is required to activate the electronics. It only exists for a few milliseconds, but can discolor a pair of contacts. This slight dis... View more
This is quite normal. The shutdown electronics safely extinguishes the electric arc. However, an initial electric arc is required to activate the electronics. It only exists for a few milliseconds, but can discolor a pair of contacts. This slight discoloration on a pair of contacts is not critical for the function of the connector.
View lessDo I need to replace the plug if several pin or socket contacts reveal soot or severe discoloration?
Yes, the connector has reached its wear limit. Please replace the connector.
