TAXNELE TXAPS3-100A 100A Automatic Phase Selector and Protection Relay

TAXNELE TXAPS3-100A Automatic Phase Selector and Protection Relay

The TAXNELE TXAPS3-100A is used by electricians when assembling electrical distribution boards to configure and monitor electrical supply parameters.

The relay operates automatically, checking voltage availability and voltage levels on phases L1, L2 and L3. Based on the measured values, it selects a suitable phase to supply a single-phase 220 V load.

If the active phase experiences overvoltage, undervoltage or voltage loss, the relay disconnects the load from that phase and switches to another available phase with voltage within the configured limits. The stated priority order is L1 > L2 > L3, and the preferred supply can be configured.

Benefits and Features

• Protection against voltage fluctuations: operating limits can be configured using the physical buttons.
• Automatic phase switching: detects voltage outside the configured limits and transfers the supply to another suitable phase.
• Configurable priority: allows selection of the preferred power supply under normal conditions.
• Adjustable current threshold from 3 to 100 A: for configuration according to the circuit being supplied.
• Reconnection time: between 1 and 500 ms.
• LCD screen: displays voltage and current parameters.
• Mounting on a standard distribution board rail.
• Settings memory: retains configured values even after a power interruption.
