Bender's LINETRAXX® series of monitoring and protection relays work on single and three-phase AC currents. In many applications the CMx420 is paired with many standard current transformers with a secondary ratio of 1 or 5A. These devices are easy to install and program which have several key benefits:
For more information on our LINETRAXX® products, please review our documents below.
The CMD420/421 current monitoring devices monitor three-phase AC currents using three measuring inputs for overcurrent and undercurrent protection. An ideal solution for those that are looking to protect and monitor the current consumption of motors on cranes, pumps and elevators. Can also be used to monitor lighting , heating and charging stations.
Compatible with many standard 1 and 5A secondary current transformers.
Key Features
The CME420 series current relays monitor undercurrent and overcurrent in single-phase AC systems as well as the current between two threshold values (window discriminator function). An ideal solution for those that are looking to protect and monitor the current consumption on emergency lighting systems, screw conveyors and single-phase pumps and drives.
Compatible with many standard 5A secondary current transformers.
