Outdoor Vacuum Circuit Breaker MZW8-12E

Parameters

Functions

Security features

The microcomputer provides three levels of protection: instant protection, time delay protection and overcurrent protection. Time-delayed protection features are flexibly adjustable. The protection values and time delay are set in accordance with the requirements of the user.

Re-enable function

It provides acceleration of protection before and after switching on, as well as coordination of the sequence of cycles. You can select the number of repeated switching on (no more than three) and various switching intervals.

Power Recovery Function

It automatically distributes energy when the ring power system is operational. In the event of a malfunction, it automatically eliminates it, isolates the defect zone, redistributes power, and restores power to the area where the malfunction is absent.

The power recovery function includes:

Switching off and fixing the state in the absence of voltage, repeated switching on, the impossibility of repeated switching on after a short time, the impossibility of very frequent repeated switching on, switching on in the absence of voltage, automatic reset, protection operation.

Measurement function

It measures such parameters as voltage, current, their harmonic parameters, active power, reactive power, power factor, frequency, and also records operating conditions and characteristics.

Remote Functions

It implements four tele functions: remote control, remote measurement, telecommunications and remote adjustment, for example, remote fault detection, remote display and registration of the measured parameter, remote parameter adjustment.

Remote control function

Turning on / off can be done remotely, which is safe and reliable, using a radio controller.
