Our SJC Series Drop-out Fuse Cutouts are engineered for superior protection of overhead distribution systems. Whether you require the lightweight, anti-pollution performance of the SJC-17K Polymer (Composite) series or the traditional, rugged reliability of the SJC-1 Porcelain series, these units ensure precise overcurrent protection and easy visual fault detection.
Core Technical Specifications
Key Features:
1. Dual Material Options for Every Environment
SJC-17K (Polymer): Features a high-grade silicone rubber housing with a 350mm leakage distance. Ideal for coastal, high-humidity, or heavily polluted areas where tracking resistance is critical.
SJC-1 (Porcelain): Utilizes high-strength glazed ceramic for maximum thermal stability and long-term UV resistance in arid or high-temperature climates.
2. Reliable Fault Interruption
Designed to handle breaking currents up to 10kA, ensuring the safety of downstream transformers and equipment during severe grid faults. The dropout mechanism is precision-engineered to prevent “sticking,” ensuring a clear visible break for maintenance crews.
3. Logistical & Installation Efficiency
Lightweight Design (SJC-17K): At only 3.8kg, the polymer unit significantly reduces shipping costs and allows for faster, safer one-man installation on the pole.
Standardized Dimensions: Compact footprints ( cm) ensure compatibility with standard NEMA mounting brackets.
4. Built for Longevity
All hardware is treated with heavy-duty galvanization or made from corrosion-resistant alloys to withstand oxidation, ensuring a service life of 20+ years in outdoor environments.
Applications
Distribution transformer protection.
Sectionalizing overhead line branches.
Capacitor bank protection.
