Strong Power Electric’s single-phase recloser is a comprehensive distribution network solution designed in compliance with IEC 62271-111-2019 (IEEE C37.60-2018). It integrates multiple technologies such as current protection, communication, and line current self-powering.

This single-phase recloser is suitable for protecting branch lines or defining consumer boundaries on overhead distribution networks. In the case of a permanent fault, it can quickly isolate the fault and prevent it from propagating to the main line. For temporary faults, it restores power through multiple reclosing operations, thereby reducing outage time and enhancing power supply reliability.

Strong Power Electric Single-Phase Recloser Benefits

• Cost-Effective Protection: A low-cost alternative to dropout fuses that reduces operating expenses and improves power supply reliability.
• Self-Powered Operation: Utilizes low-current technology, powered directly from the line via the power CT with no need for external power sources.
• High-Performance Interruption: Features maintenance-free vacuum arc extinguishing technology with a maximum interrupting current of 6300A.
• Ultra-Reliable Mechanism: Permanent magnet mechanism ensures low power consumption, high reliability, and a 10,000-operation mechanical lifespan.
• Sustainable & Easy to Deploy: Crafted from recyclable thermoplastic for easy installation on existing brackets and simplified maintenance with wireless configuration and a hot-swappable external battery.

Single phase vacuum recloser component composition

The single phase vacuum recloser consists of a casing, a vacuum interrupter, a magnetic mechanism, a control unit, modules, etc. Each module is sealed in the casing and isolated from the atmosphere.

Differences Between Single-Phase Recloser, Three-Phase Recloser, and Sectionalizer

Feature	Single-Phase Recloser	Three-Phase Recloser	Sectionalizer
Number of Phases	Single-Phase	Three-Phase (simultaneous operation)	Can be single or three-phase
Core Function	Can interrupt fault current and perform auto-reclosing	Can interrupt fault current and perform auto-reclosing	Cannot interrupt fault current
Operating Principle	Detects and operates based on the fault current passing through it.	Detects and operates based on three-phase fault currents.	“Counts” the opening operations of the upstream breaker/recloser. Opens to isolate the fault after a preset number (during dead time).
Cost & Complexity	Lower, Simpler	Higher, More Complex	Lowest, Simplest
Typical Application	End of lines, branch feeders	Main lines, power source entry points	Line segmentation points, relies on upstream protection
