  • Protection Type

    Overvoltage

    Monitors current consumption in Amperes (A). If the connected devices draw more current than the safety limit, the monitor cuts off the supply to prevent overheating of the cables and the risk of fire.

    Undervoltage

    Protects against dangerous voltage drops (e.g. < 190V). It is essential for devices with motors and compressors (air conditioners, refrigerators, pumps), which overheat and are damaged when they try to operate at low voltage.

    Phase Asymmetry

    Checks whether there is a large voltage deviation between the 3 phases (e.g. L1 = 230V, L2 = 180V). Protects three-phase devices from irregular operation, vibrations, and overheating.

    Phase Sequence

    Ensures that the phases are connected in the correct sequence (L1, L2, L3). Prevents three-phase motors and pumps from rotating in reverse, avoiding serious mechanical damage.

Description

Description

Three-Phase Sequence and Asymmetry Monitor without Neutral PELC-PT432-8PIN.

It is used to protect asynchronous three-phase motors from anomalies in the electric power distribution network. A characteristic application is the protection of submersible pumps.

It monitors the three-phase network voltage concerning:

  • Loss of one or more phases
  • Asymmetry of the three phases (adjustable 25-5%)
  • Sequence
  • Undervoltage

It operates without a neutral connection. The monitor's relay is activated when all three phases of the network do not deviate from each other by more than the adjustable value, and their sequence is correct. In any other case, as well as in the case of total loss of a phase (below 300VAC), the relay is deactivated.

Specifications:

  • Power Supply: 230V AC / 50Hz
  • Output Relay: Single changeover contact 10A / 250VAC cat. AC1
  • LED Indicators: POWER ON and RELAY ON
  • Protection: Varistor (against surges and lightning)
  • Electrode connection cables: Cross-section 1 – 2.5mm², maximum cable length 500m
  • Operating Temperature: -20º to +50º C

The controllers are also available with double-contact relays and with an 11-pin base.

Package Dimensions (L x W x H): 10.50 x 5 x 10cm

Weight: 0.200kg

Package Contents: 1x PELC-PT432-8PIN Three-Phase Sequence and Asymmetry Monitor
