ARM6Z-250-3300 liquid crystal type remote control mccb 400VAC 250A 3 Poles LCD display mccb
Purpose and scope of application
ARM6Z series intelligent measuring circuit breaker (hereinafter referred to as circuit breaker) is suitable for distribution protection of circuit 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 device 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 system.
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.
Our company has launched this new circuit breaker aimed at the development needs of smart grids. This series of product has multiple independent innovative technologies of our company.
The circuit breaker can be installed vertically (i.e. upright), horizontally (i.e. transversely).
The circuit breaker has isolation function, and its corresponding symbol is:
