Auto Recloser Circuit Breaker Manufacturer
Reliable power distribution requires fast fault detection, automatic fault isolation and quick restoration of supply. An Auto Recloser Circuit Breaker (ARCB) is designed to perform these functions automatically on medium-voltage overhead distribution networks.
Eastland Switchgears Pvt. Ltd. (ESPL) manufactures and supplies 11kV Auto Recloser, 33kV Auto Recloser, Pole Mounted Auto Recloser and Sectionalizer solutions for utility, industrial, infrastructure and distribution network applications.
Our SDV Series Auto Reclosers are designed for outdoor installation and modern distribution automation applications, with vacuum interruption, solid dielectric insulation and SCADA-compatible control options. The ESPL product range covers SDV12 for 11kV systems, SDV27 for 22kV systems and SDV36 for 33kV systems.
What is an Auto Recloser Circuit Breaker?
An Auto Recloser Circuit Breaker (ARCB) is an intelligent medium-voltage switching and protection device used in electrical distribution networks.
Unlike a conventional circuit breaker that normally requires a separate switching or protection arrangement, an auto recloser can detect a fault, open the circuit, wait for a predefined time and automatically reclose the line.
If the fault was temporary, such as a momentary contact with a tree branch, lightning-related disturbance or transient fault, the line can return to normal operation.
If the fault continues, the recloser performs additional programmed operations and finally locks out the affected circuit.
This automatic operation helps utilities reduce unnecessary interruptions and improve the reliability of overhead distribution feeders. The basic operating principle is also described by major recloser manufacturers as automatic opening, timed reclosing and lockout when the fault persists.
How Does an Auto Recloser Work?
The working principle of an Automatic Circuit Recloser is based on detecting abnormal current or other programmed protection conditions and automatically controlling the feeder.
A typical operating sequence includes:
Normal Condition → Fault Detection → Circuit Opening → Time Delay → Automatic Reclosing → Fault Check → Reclose or Lockout
Step 1: Normal Power Flow
During normal operation, the auto recloser remains closed and allows electrical power to flow through the distribution feeder.
Step 2: Fault Detection
When a fault occurs, the protection system detects abnormal electrical conditions such as overcurrent or earth fault.
Step 3: Circuit Interruption
The recloser opens the circuit to isolate the faulted section and protect downstream equipment.
Step 4: Automatic Reclosing
After a programmed time delay, the device automatically attempts to close the circuit again.
Step 5: Temporary Fault Clearance
If the fault has disappeared, the feeder can return to normal operation without requiring manual intervention.
Step 6: Permanent Fault Protection
If the fault remains, the recloser repeats the programmed sequence and eventually goes into lockout condition.
This operating principle makes an auto recloser particularly useful for overhead distribution networks where temporary faults can occur frequently.
11kV Auto Recloser
An 11kV Auto Recloser is widely used for medium-voltage distribution feeders, rural electrification networks, utility systems and industrial power distribution.
ESPL’s SDV12 is designed for 11kV distribution applications and outdoor installation. The product is available with protection and automation capabilities suitable for modern distribution networks.
Typical Applications of 11kV Auto Recloser
- 11kV overhead distribution feeders
- Rural electrification projects
- Utility distribution networks
- Industrial feeders
- Distribution substations
- Smart grid projects
- Renewable energy distribution networks
- Feeder automation systems
An 11kV pole-mounted auto recloser can be installed directly on suitable distribution structures, making it practical for overhead feeder protection and automation.
33kV Auto Recloser
A 33kV Auto Recloser is used for higher-voltage distribution and sub-transmission applications where reliable fault protection and automatic restoration are required.
ESPL’s SDV36 is designed for 33kV applications and provides a solution for overhead distribution networks, industrial power systems and utility applications.
Applications of 33kV Auto Recloser
- 33kV overhead distribution lines

For projects requiring remote monitoring and automated network control, a SCADA-compatible auto recloser can be integrated with the wider distribution automation system.
Pole Mounted Auto Recloser for Overhead Distribution Lines
A Pole Mounted Auto Recloser is installed on overhead electrical distribution structures and is designed to protect feeders from temporary and permanent faults.
Pole-mounted installation can reduce the requirement for dedicated indoor switchgear rooms and makes the equipment suitable for outdoor distribution applications.
ESPL’s auto recloser solutions are designed for outdoor environments and can be configured for utility and industrial distribution applications.
Key Benefits of Pole Mounted Auto Reclosers

Auto Recloser and Sectionalizer – What is the Difference?
Both Auto Reclosers and Sectionalizers are important components of modern distribution protection systems, but they perform different functions.
An Auto Recloser Circuit Breaker can detect fault conditions and interrupt the current before automatically attempting to restore supply.
A Sectionalizer, on the other hand, is generally used to isolate a faulted section of the distribution network in coordination with an upstream protective device.
Auto Recloser
- Detects fault conditions
- Interrupts fault current
- Automatically recloses
- Provides feeder protection
- Can support remote monitoring and automation
Sectionalizer
- Isolates a faulted section
- Works in coordination with upstream protection
- Helps reduce the outage area
- Supports distribution network sectionalizing
Using both devices in an appropriately designed network can help improve distribution system reliability and fault management.
