BENDER PRODUCT GROUP GUIDE
Monitor electrical limits for the application
Undervoltage or overvoltage, phase failure, phase sequence and current changes can affect equipment operation. Bender measuring and monitoring relays evaluate the selected quantity in main and auxiliary circuits and supply status information to the alarm and control chain.

Identify the measurement function
Voltage and frequency, current and protective conductor loop monitoring are different tasks. Relay selection starts with the quantity to be monitored.
Match system and supply
Measuring connections differ for single-phase AC/DC and three-phase circuits. The device’s own supply and measuring circuit limits are checked together.
Adapt response to operation
Thresholds, delays and contact behaviour are defined according to the selected model’s scope. Technical tables on model pages and current data sheets complete the selection process.

BENDER MEASURING AND MONITORING RELAYS
Select protection relays by function.
Identifying the monitored quantity is the first step in selecting a protection relay. Bender’s LINETRAXX® portfolio includes different relays for voltage and frequency, phase, current and loop resistance monitoring. Request model selection support, technical documentation and a supply quotation from ADEO Teknik.
What is the difference between voltage and current relays?
A voltage relay monitors voltage and, depending on the model, frequency/phase conditions; a current relay monitors current magnitude. The two groups address different measurement needs.
What information is needed to select a relay?
Specify AC/DC configuration, phase count, measurement range, supply voltage, threshold/delay requirements and outputs.
