DC connectors from Phoenix Contact can be safely connected and disconnected under load. The ArcZero series provides you with reliable protection against hazardous electric arcs. The capability of being connected under load enables selected components to be fully shut down, thus ensuring high system availability. The impact strength of the low-voltage connectors also enables DC connections to be established under extreme conditions.

DC applications are becoming increasingly more established in the markets, since they offer many advantages like reduced conversion losses. Nevertheless, up to now, disconnecting under load has produced a dangerous electric arc. Not so, however, with the DC connectors of the ArcZero series from Phoenix Contact. These reliably protect you against electric arcs and thus enable safe connection and disconnection under load.
This allows you to safely shut down selected parts of the system when you need to replace parts or service a device, while the rest of the system remains in operation. This means high availability – with downtimes being a thing of the past.
Safe connection and disconnection under load become possible for the first time. The special feature is integrated in the DC connector. An innovative piece of electronics, directly built into the connector, actively quenches the electric arc. This solution protects the operator during the maintenance of operating systems.
The DC connector proves advantageous also in field cabling. The locking, which can be opened manually, enables the connection to be disconnected easily and without additional tools. This solution ensures particularly easy handling during installation and maintenance.
When a device needs to be replaced during maintenance, this can now be done under load without any problems. You no longer need to disconnect the entire system from power. This results in less downtime, high system availability, and even more efficiency. Safety is ensured without limitation.
The shockproof DC connector was designed for use even in extreme conditions. High degrees of protection up to IP69 ensure reliable power distribution. Even demanding environmental conditions pose no problems. The impact strength up to IK08 makes ArcZero a robust solution, even for high mechanical requirements.
The high number of insertion cycles make the ArcZero series particularly durable and cost-effective. To ensure a long-term stable connection without failure, the quality of the contact points was extensively tested in a certified laboratory beforehand.
The transition from AC grids to DC grids is becoming increasingly important. In an interview, product specialist Andreas Beck explains how the ArcZero series connector can facilitate this change and what advantages it offers.
Award for Phoenix Contact DC connectors: ArcZero made it to the top of the winner’s podium. Readers of the German trade journal “Elektronik” and the online platform elektroniknet.de voted the DC connector as the winner in the “Electromechanics and passive components” category. Product Manager Andreas Beck proudly accepted the award in Munich in March 2024.
The connector is resistant to impacts of class IK08 at temperatures down 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.
Yes, mechanical loads, e.g., due to cables, need to be supported up to 50 cm behind the connector through cable ties. The bending radius of the cable must also be observed.
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.
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 operators from suffering an electric shock.
All items of the series are equipped with screw connection technology with wire guard.
Yes, the connector has reached its wear limit and should then be replaced.
