Carlo Gavazzi DPB and DPC

Carlo Gavazzi has added several three-phase monitoring relays, featuring a wider input voltage range.

These new models, part of the DPB and DPC families, feature an upgraded switch mode power supply, which provides a wider input voltage range to cover different mains voltages, while reducing heat dissipation and improving reliability and stability.

The DPB series has an input voltage range of 208 VAC to 480 VAC, while the DPC series has an input voltage range of 208 VAC to 690 VAC.

All of the new models feature an expansive frequency range of 50 Hz to 400 Hz, making them ideal for a wide range of applications.


Three-phase monitoring relays are ideal for protecting motors from severe damage that can result from loss of a phase, phase imbalance or phase reversal. Motors can be found in a wide range of applications, including: HVAC systems, water treatment, material handling, machine tool, marine and aviation.

Key features of the DPB and DPC three-phase monitoring relays include noise, harmonics and transient filtering, significant reduction in power consumption versus previous models, wide input voltage and frequency range, voltage ranges selectable by DIP switches, DIN rail mounting and a plug-in option available for DPB series.
