Product information

Description

ETI-Polam PZAK-1 phase sequence and asymmetry loss relay is a compact monitoring device for three-phase electrical supplies. It detects phase reversal, phase loss and significant phase imbalance, and provides a single changeover contact rated for 8 A to interrupt control circuits or signal alarms. The relay is intended for installation in industrial and commercial distribution panels to protect motors, drives and other three-phase equipment from incorrect rotation and supply problems.

Advantages

The relay offers reliable detection of wrong phase sequence, missing phase and asymmetry with a compact form factor suitable for DIN-rail mounting. Its single changeover contact simplifies wiring to contactors, alarm circuits or PLC inputs, while the 8 A contact rating covers common control and signaling loads. Low installation footprint and clear functional behaviour make it straightforward to integrate into existing electrical panels.

Suitable for

  • Protection of three-phase motors and motor starters
  • Monitoring of drives and pumps in industrial installations
  • Control and alarm signalling in commercial electrical panels
  • Verification of correct phase rotation during commissioning

Key specifications

  • Function: phase sequence monitoring and phase asymmetry (phase loss) detection
  • Contact type: single changeover (SPDT)
  • Contact rated current: 8 A
  • Supply system: three-phase input monitoring
  • Mounting: panel / DIN-rail compatible compact housing

How to use

Install the relay in the distribution or control panel in accordance with local electrical codes. Connect the three phase conductors to the device terminals for continuous monitoring of phase sequence and asymmetry. Wire the single changeover contact into the control circuit of the contactor, alarm lamp or PLC input so that the contact changes state when an incorrect phase sequence, phase loss or excessive imbalance is detected. Verify correct wiring and perform a functional test during commissioning to confirm correct response to phase reversal and phase loss conditions.

Usage recommendations

Use the relay as part of a layered protection scheme: combine it with appropriate overcurrent, thermal and motor protection devices. Ensure regular inspection of connections and periodic functional testing after installation to maintain reliable protection of motors and three-phase equipment.
