What is auto recloser?
The Auto Recloser (ARC) is a sophisticated automated switching device designed to significantly boost power reliability in overhead distribution networks. It quickly detects and interrupts momentary faults, playing a crucial role in minimizing outages. By automatically restoring service after temporary faults, ARCs dramatically reduce outage durations.
For instance, an ARC acts instantaneously when a transient fault occurs on an 11kV or 33kV overhead line, like a tree limb contact or a lightning strike. It automatically opens to clear the fault, then recloses after a brief interval to restore power if the fault was temporary. If the fault persists, the ARC attempts reclosure a set number of times before locking out, indicating a permanent issue.
This intelligent operation greatly reduces the frequency and length of power disruptions. Our Auto Reclosers are indispensable for maintaining grid stability and enhancing service continuity in critical 11kV and 33kV power lines.

Auto Recloser – FAQs
What is an Auto Recloser used for?
An Auto Recloser automatically interrupts and restores power in overhead lines after transient faults, minimizing outages and improving service continuity.
How does an ACR work?
It detects a fault, opens the circuit, and attempts to reclose it after a short delay. If the fault clears, power is restored without manual intervention.
Where is an Auto Recloser commonly installed?
It is typically installed in utility overhead lines, substations, or industrial distribution networks for medium voltage protection and automation.
Is the Auto Recloser programmable?
Yes, our Auto Reclosers are microprocessor-controlled and fully programmable for timing, current thresholds, and reclosing sequences.
Can the Auto Recloser be customized?
Absolutely. We support customization for rated voltage, rated current, trip curve, communication protocol, and installation type.
What types of structures can the Auto Recloser be installed on?
Our ACRs are designed for versatile installation and can be securely mounted on both **concrete poles** and **H-frame steel structures**.
What are the mounting orientations available?
The Auto Recloser supports flexible mounting options, allowing for installation in both **vertical and horizontal orientations** to best fit site-specific requirements.
Which communication protocols are compatible with the control unit?
The control unit offers broad compatibility, supporting industry-standard protocols such as **DNP3, IEC 61850, IEC 60870-5-104, 101, and Modbus**.
Can the Auto Recloser integrate with SCADA systems?
Yes, our Auto Recloser's control unit is designed to support communication with **SCADA ABB SYS600 software**, facilitating seamless integration into existing Supervisory Control and Data Acquisition systems.
Is your Auto Recloser suitable for harsh environments?
Yes, it is sealed, weatherproof, and built to operate in extreme temperatures and outdoor environments without maintenance.
What is the delivery time?
Standard delivery time is 10–15 working days. Customized products may require 3–4 weeks depending on specifications.
What payment methods do you accept?
We support T/T, L/C. For long-term cooperation, flexible payment terms can be discussed.
Do you provide after-sales support?
Yes, we offer technical support, installation guidance, and a standard 12–24 month warranty depending on the product.
