1. Summarize
ASCB1 series of intelligent miniature circuit breakers are used for low-voltage
terminal distribution network in industrial, commercial, civil buildings and
infrastructure fields in indoor buildings and similar places. The intelligent circuit
breaker is used with the intelligent gateway to monitor the key electrical elements
of the power line, such as voltage, current, power, temperature, leakage, energy
consumption and so on. It has the functions of remote control, early warning

protection, short circuit protection, energy metering statistics, fault location and so
on.
This series of products are suitable for single phase, double live wire, three
phase three wire, three phase four wire neutral point direct grounding (TT) low
voltage power grid system.

4.2. Installation method
1) The equipment is suitable for standard 35mm guide rail
installation, installation only need to put the equipment into
the track and buckle fixed.
2) According to the actual distribution management and line
laying design requirements, select and use the required

Internet of Things modules and specifications of the electrical
box, and install the modules in combination according to the
sequence shown in the picture. Each module is connected with
the manufacturer's special 8-pin data cable.
3) The circuit breaker should be installed vertically. When the
handle is in the "/OFF" state, the contact is disconnected.
When the handle moves upward, the contact moves in the closed
direction.
4) The nominal cross-sectional area of copper wire matching the
rated current of circuit breaker is shown in Table 5.
