ASTfuse

INTELLIGENT THREE-PHASE DISCONNECT SWITCH AND ENERGY METER

Device Description

ASTfuse is an intelligent three-phase disconnect switch that combines remote switching capabilities with advanced energy monitoring. The device integrates the functions of a disconnect switch, protective device, and energy analyzer into a single solution, providing complete supervision and control of electrical installations.

Designed for installation on a standard DIN rail, ASTfuse enables remote switching of electrical circuits, real-time monitoring of electrical parameters, and automated operation based on programmable schedules or user-defined scenarios.

With integrated Wi-Fi communication and full compatibility with the ASTonline management platform, ASTfuse is an advanced component of modern energy management systems, suitable for street lighting installations, industrial applications, commercial buildings, and smart building automation.


Intelligent Energy Management

ASTfuse continuously measures electrical parameters independently for each phase, providing detailed information about the operating condition of the electrical installation.

Measured parameters include:

  • Voltage
  • Current
  • Active power
  • Energy consumption

Real-time monitoring enables accurate energy analysis, early detection of abnormal operating conditions, and optimization of energy consumption.


Remote Control and Automation

ASTfuse allows remote switching of electrical circuits from anywhere via Wi-Fi and the ASTonline platform.

Using the mobile application or web interface, users can:

  • Switch electrical circuits on and off remotely.
  • Create weekly operating schedules.
  • Configure timers.
  • Automate switching sequences.
  • Monitor energy consumption.
  • Control the device using a smartphone or tablet.

The controller is also compatible with popular smart home ecosystems, supporting voice control through Google Home and Amazon Alexa.


Safety and Reliability

ASTfuse is equipped with a high-speed switching mechanism and advanced protection functions designed to ensure reliable operation under demanding conditions.

Integrated 6 kV surge protection safeguards the installation against lightning-induced transients and electrical disturbances, while the robust servo-driven switching mechanism ensures fast and reliable operation.

An external antenna with a magnetic base provides stable wireless communication even when installed inside metal electrical cabinets.
