High-Quality 160A Three-Phase Fire Protection Current Limiter - China Suppliers & Factory for Electrical Safety Solutions Factory, Companies

Functions & Applications

• 📡
  Real-time Monitoring

  The electrical fire current-limiting protector can monitor the controlled circuit's short-circuit current, fault arc (optional), voltage, current, frequency, temperature, residual current, and remote communication status in real-time, displaying them clearly.

• 🔔
  Alarm & Protection Function

  When the electrical fire current-limiting protector detects a short circuit, fault arc (optional), or abnormal power consumption data, it triggers audible and visual alarms. It performs current-limiting protection within microseconds to ensure safe electricity usage.

• ⚠️
  Fault Indication Function

  If the electrical fire current-limiting protector detects internal faults—such as malfunctions in the fault arc detection function or temperature sensor probe—it emits an audible and visual signal to alert users to perform maintenance.

• 📶
  Communication Function

  The electrical fire current-limiting protector is equipped with an RS485 communication interface or a 4G communication module. Through 4G, it transmits various power consumption data to the smart safety monitoring cloud service system, forming a smart power safety supervision service network.

Frequently Asked Questions

• Q What is an electrical fire current-limiting protector and how does it work?

  An electrical fire current-limiting protector is a smart safety device that monitors circuit parameters such as voltage, current, temperature, and leakage current in real time. When it detects abnormal conditions like short circuits or fault arcs, it activates current-limiting protection within microseconds to prevent electrical fires.

• Q What rated current options are available for this protector?

  The electrical fire current-limiting protector is available in multiple rated current options: 20A, 32A, 40A, 50A, 63A, 80A, 100A, 125A, and 160A, making it suitable for a wide range of residential, commercial, and industrial applications.

• Q What communication methods does the protector support?

  The device supports RS485 wired communication, as well as wireless options including LORA, NB-IoT, and 4G (optional). Through 4G connectivity, it can upload power consumption data to a smart safety monitoring cloud platform for remote supervision and management.

• Q What types of faults can this device detect and protect against?

  The device can detect and protect against short circuits (response time <150µs), overloads, overvoltage, undervoltage, excessive wire temperature, and leakage current. An optional fault arc detection function is also available for enhanced fire prevention.

• Q What are the installation requirements and available dimensions?

  The protector uses bottom screw mounting for easy installation in standard electrical cabinets. Two size models are available: 270(L)×180(W)×118(H) mm and 430(L)×240(W)×158(H) mm, to accommodate different circuit capacities and enclosure requirements.

• Q What operating temperature range does this device support?

  The electrical fire current-limiting protector is designed to operate reliably across a wide temperature range of -20℃ to 85℃, making it suitable for both indoor and outdoor electrical cabinet installations in varying climate conditions.
