Product Description

Purpose and Scope of Application

ARM6Z series intelligent measuring circuit breaker is suitable for distribution protection of circuits with frequency of AC 50Hz/60Hz, rated working current 125A to 250A, rated insulation voltage 1000V and rated working voltage AC380V. The measuring switch has functions such as long delay, short circuit short delay, instantaneous, overvoltage/undervoltage and phase failure protection, providing protection for the line and power equipment.

With the ability to provide feedback on product current, voltage, power, energy and other information to terminal devices with accuracy up to the meter level, it's used for detecting and monitoring the load end, reducing the operation and maintenance cost of the power grid, and providing necessary data for future energy efficiency systems.

The measuring switch also has functions such as automatic identification of distribution network topology relationship, error monitoring of energy meter and power line carrier communication.
This new circuit breaker has been launched to meet the development needs of smart grids, featuring multiple independent innovative technologies.
The circuit breaker can be installed vertically (i.e. upright) or horizontally (i.e. transversely).
The circuit breaker has an isolation function, and its corresponding symbol is: Isolation function symbol
Meets standards: IEC60947-2 & GB/T14048.2
