TOMZN TOVPD3-100VAYA 100A 3 Phase Auto Phase Selector with Voltage Protection & Monitoring

TOMZN TOVPD3-100VAYA 100A 3 Phase Auto Phase Selector with Protection and Monitoring

The TOMZN TOVPD3-100VAYA 100A 3 Phase Auto Phase Selector is an electrical control and protection device designed for compatible three-phase power systems. It combines automatic phase selection with voltage protection and monitoring functions, helping manage electrical supply conditions in three-phase, four-wire installations.

With a rated current of 100A and support for 230V/400V AC systems, this device is designed for electrical distribution applications where phase availability and voltage conditions are important.

100A Rated Current Capacity

The TOMZN TOVPD3-100VAYA has a specified rated current of 100A. This rating is an important consideration when selecting a phase selector for an electrical installation.

The connected circuit, wiring, protective devices, and overall installation must be suitable for the device's rated current. Always follow the manufacturer's electrical specifications.

Three-Phase Automatic Phase Selection

This device is designed for three-phase electrical systems and provides automatic phase selection functionality.

Automatic phase selection can help manage the supply when phase conditions vary. It is intended for installations where selecting an available suitable phase is important for maintaining the connected electrical supply.

The exact phase-priority logic, switching sequence, and transfer timing have not been provided in the supplied specifications.

3 Phase 4 Wire Electrical Compatibility

The TOMZN TOVPD3-100VAYA supports a three-phase, four-wire configuration (3P+N).

Its specified voltage ratings are:

• Line-to-Neutral (L-N): 230V AC

• Line-to-Line (L-L): 400V AC

This configuration makes it suitable for compatible three-phase electrical distribution systems.

Voltage Protection and Monitoring

The product is identified as an automatic phase selector with protection and monitoring.

Voltage monitoring helps users assess electrical supply conditions, while the protection functionality is intended to help manage voltage-related operating conditions.

The exact overvoltage and undervoltage thresholds, protection delay, and recovery settings have not been specified in the supplied information. These details should be confirmed from the manufacturer's complete technical documentation.

Operating Voltage Range

The supplied operating voltage range begins at 150V–300V AC, but the specification is incomplete. The full phase-specific operating range should be verified before installation or final technical publication.
