Monitoring relay, DPA51 series Phase and SPDT contacts, DPA51CM44

Reliable overcurrent monitoring

The Carlo Gavazzi overcurrent monitoring microrelay is the ideal solution for protecting electrical circuits from overvoltage. Thanks to the possibility of connecting to MI or MP current transformers, this model can be used for both single-phase and three-phase applications. The built-in latch function allows the relay output to remain on, ensuring greater safety and operational stability. The red LED indicator provides a visual indication of the alarm status, allowing for a quick response to dangerous situations.

Flexible settings and wide measuring range

The device offers several measuring ranges from 2 V AC/DC up to 500 V AC/DC, allowing for a wide range of applications. Two-position microswitches allow easy selection of the measuring range, while the adjustable voltage limit on a relative scale provides the user with the ability to customise the settings according to specific requirements. Thanks to adjustable hysteresis and programmable persistent mode at the selected level, it is possible to achieve optimal sensitivity and measurement accuracy.

Compact dimensions and easy installation

The relay is designed for DIN rail mounting, which facilitates installation in switchboards and industrial applications. Thanks to its compact dimensions of 67.2 × 17.5 × 81 mm, it takes up minimal space, which is advantageous in environments with limited space. Galvanically isolated power supply ensures a high level of safety and reliability. The device is also resistant to phase loss and incorrect phase sequence, making it suitable for three-phase systems with a voltage range from 177 V to 550 V AC.
