Overcurrent release DPX3 630-1600, 230V AC/DC 422242

Overcurrent release for DPX3 circuit breakers – reliable remote disconnection

The DPX3 630-1600 overcurrent release is a component used for remote disconnection of power circuit breakers and disconnectors from the DPX3 series. It enables a quick response in the event of exceeding the permissible control voltage values, protecting the electrical installation from damage. This is particularly important in systems where remote control and safety are crucial.

Versatility and compatibility

The device is compatible with both AC and DC voltage of 230V, providing a wide range of applications. Designed to work with DPX3 series circuit breakers with rated currents from 630A to 1600A, it performs perfectly in installations with medium and high loads. The possibility of use with both circuit breakers and disconnectors increases the flexibility of designing and modernizing electrical installations.

Design features and application

The DPX3 overcurrent release is designed as a release coil, which means that after receiving a control signal, it immediately disconnects the circuit. This provides effective protection against overloads and short circuits. The device finds application in:

• Energy infrastructure: transformer stations, energy distribution systems – where precise control and quick remote disconnection of circuits are required.
• Industrial electrical installations: protection of machines and equipment against damage caused by overvoltage or improper operation of the control system.
• Commercial and public buildings: ensuring the safety of users and protecting against failures of the electrical installation.

Additionally, thanks to the possibility of mounting additional accessories (e.g. auxiliary contacts), the functionality of the release can be extended and adapted to the specific needs of a given installation. It is worth noting the possibility of connecting mechanical locks for increased safety.
