Phase Selector Switches L48E… - L52E… connection diagram

Commonly used phase selector switch in three-phase systems. Available switching options include:

  • Phase-phase or phase-neutral voltages using a single voltmeter
  • Selection of three currents using a single ammeter

Phase selector switches L48E… – L52E… are reliable devices designed for use in three-phase systems, providing flexible phase selection in industrial installations and power networks. They allow maintaining continuity of power supply to single-phase loads in case of phase failure or voltage drop below the standard.

Functions and Applications

  • Automatic or manual phase selection: phase-phase or phase-neutral using a single voltmeter.
  • Selection of three currents using a single ammeter, allowing efficient current measurement and system monitoring.
  • Maintaining power continuity in case of phase loss, ensuring proper operating parameters for loads.

Installation and Connection Diagram

L48E… – L52E… feature an intuitive connection diagram that facilitates quick and safe installation in three-phase systems. The switch input is connected to the phases, and the output is directed to a single-phase load or measuring devices, ensuring proper operating parameters and system protection.

Phase selector switches L48E… – L52E… (automatic phase switch) are reliable electronic devices providing flexible phase selection, maintaining power continuity, and ensuring proper operating parameters for single-phase and industrial loads. With robust construction, high protection degree, and compliance with CEI EN-DIN and VDE-IEC standards, they are an ideal solution for power networks and industrial automation systems.
