Product Specification

ECT-LPS1 current sensor is a three -phase integrated structure, epoxy resin casting, high insulation strength, safe and reliable, application for the installation of common box type outdoor column circuit breaker (ZW20) or outdoor column load switch (FZW28) with good condensation resistance. It is application for current measurement (measurement) and protection in AC 50/60 Hz lines with the highest voltage of 12kV and below.

Secondary Terminals

In order to ensure good anti-interference ability, ECT-LPS1 current sensor secondary signal terminals and signal line have been specially shielded, and customized interface schemes can be provided according to customers' specific requirements.

Principle and characteristics

The ECT-LPS1 current sensor is based on the low-power coil principle and has the fllowing advantages:

●The integrated design can realize the measurement of phase current and zero sequence current at the same time and the protection signal sampling.

●The secondary output is a safe low voltage signal, the power consumption is greatly reduced, and the heat output is small.

●No secondary open circuit high voltage risk, increased safety.

●Product standardization, selection and ordering process simplification, fast delivery. 

●Small size, light weight, easy to install.

Combined with the versatile itelligent feeder terminal (FTU), these excellent features will greatly improve power protection and monitorinc
