PTE480-AD0EST 3 fases 480 – Three-Phases Electronic Voltage Protector 480 VAC, Omega DIN rail

The BREAKERMATIC 3 fases for DIN RAIL monitors line voltages for a three-phase appliance, protecting it against voltage fluctuations and preventing the machine from starting when the phase rotation direction has been reversed or when a phase is missing.

The BREAKERMATIC 3 fases for DIN RAIL has front adjustment knobs that allow you to select the high and low cut-off voltages. You can also adjust the reconnection delay after a voltage failure. The knobs are protected by a transparent cover that can be sealed to prevent accidental tampering with the settings.

The BREAKERMATIC 3 fases for DIN RAIL output consists of a de-energized relay, which can control an external contactor or any stop signal that allows the machine to stop.

The disconnection operation is automatic, as is the reset after the fault disappears.

The protector displays faults and output status using five indicator LEDs clearly identified on the front label.

It can be mounted using an omega rail (DIN rail) for electrical panels, or directly to a wall using screws placed through built-in fixing brackets.

Ideal for

• Hydro pneumatic pumps
• Elevators and three-phase motors
• Refrigeration, ventilation, and air conditioning equipment
• Industrial transport.

Operation

Protection against steady-state voltage variations

The BREAKERMATIC 3 fases for DIN RAIL disconnects the output if the steady-state line voltage is above the voltage set on the "high voltage" knob or below the voltage set on the "low voltage" knob. The response time is 1 second. The voltage must remain outside the range longer than the response time for the disconnection to be activated. While the fault persists, the corresponding indicator will remain lit.

Reconnection delay or standby cycle

When the protector is energized, or at the end of a voltage fault, the protector will initiate a time delay before connecting the output. The duration of the time delay can be adjusted using the "wait cycle" knob between 5 s and 300 s (5 min). The standby cycle protects sensitive equipment from short operating cycles. 

Blackouts and brownout detection.

The protector will disconnect the load if it detects a sudden voltage drop below 50% of the nominal voltage and will initiate a standby cycle. The response time of the blackout detector is instantaneous; the minimum blackout duration is specified in the specifications, but it is guaranteed to be greater than the maximum transfer time on the distribution lines. Therefore, this maneuver does not affect the protector and does not disconnect the load.

Absence of a phase.

The protector will disconnect the output and indicate absence of a phase.

Reversal of the direction of rotation or phase sequence.

If the phase sequence is reversed, the protector will immediately disconnect the output. The response time to this disturbance is less than one line cycle.
