China 80/125A Economic Three-phase Current-limiting Protector Manufacturers, Factories

The Economic Electrical Fireproof Current-limiting Protector is an intelligent electrical safety monitoring device. It accurately detects circuit current and limits short-circuit current within milliseconds to extinguish arcs and protect circuits. Integrated with voltage, current, frequency, leakage current, temperature and optional arc fault detection, it features intelligent analysis. It triggers audible and visual alarms and uploads signals to the cloud for real-time warnings, eliminating hidden dangers, preventing fires and ensuring comprehensive circuit protection for residential and industrial use.

Product Description

System Overview

The electrical fireproof current-limiting protector is specifically designed to address issues such as short circuits and overloads in low-voltage distribution lines. It effectively overcomes the shortcomings of traditional circuit breakers, air switches, and monitoring equipment, including high short-circuit current, long short-circuit current interruption time, large arc sparks during short circuits, and short service life.

In the event of a short circuit fault, it can rapidly limit the short-circuit current at microsecond speed to achieve arc extinction and protection, thereby significantly reducing electrical fire incidents and ensuring the safety of personnel and property in the premises where it is used.

The electrical fireproof current-limiting protector can be widely applied in various electrical locations for end branch and main circuit protection, including schools, hospitals, shopping malls, hotels, entertainment venues, temples, heritage buildings, libraries, archives, exhibition centers, residential buildings, warehouses, kindergartens, senior housing, collective dormitories, electric vehicle charging stations, leased retail shopping mall units, wholesale markets, farmers' markets, and Class A, B, and C hazardous goods warehouses.

Special Notes:
  • The front end is a residual current device (RCD). The live and neutral wires are routed from the output terminals of the RCD to the current-limiting protector.
  • The neutral wire connected to this protector passes through the protector to the terminal load equipment.
  • RS485 communication is an auxiliary function and may not be connected in practical applications.

Frequently Asked Questions

What are the main advantages of a current-limiting protector over traditional circuit breakers?
Unlike traditional breakers, this protector can limit short-circuit currents at microsecond speeds, effectively eliminating arc sparks and preventing electrical fires before they start.
In which environments is this electrical fireproof protector most recommended?
It is ideal for high-density or high-risk locations such as schools, hospitals, heritage buildings, shopping malls, and warehouses storing hazardous goods.
What are the physical dimensions of the 80-type protector?
The standard dimensions for the 80-type model are 105mm in length, 130mm in width, and 76mm in height.
Does the protector support remote monitoring or communication?
Yes, it features RS485 communication as an auxiliary function, allowing for integration into monitoring systems, though it is not mandatory for basic operation.
How is the protector wired in relation to an RCD?
The protector should be connected after a Residual Current Device (RCD), with live and neutral wires routed from the RCD output to the protector's terminals.
Can this device be used for electric vehicle charging stations?
Yes, it is highly recommended for EV charging stations to provide rapid short-circuit protection and enhance overall electrical safety.
