JUNW PG Circuit Breaker Protection Box

PG Series Circuit Breaker Protection Box
1. Compliance & Core Material Advantages
This PG series protection box is strictly produced in accordance with IEC 60439-3 international standards, adopting PC+ABS fire-retardant material for its shell. Finished in a clean white color, this material integrates high mechanical strength, reliable electrical insulation, and excellent flame-retardant properties, effectively blocking flame spread and resisting mechanical impact to protect internal circuit breakers.

2. Safety Protection Performance
It meets IEC 60529 IP30 ingress protection, preventing solid foreign objects from entering and avoiding dust or debris interference with circuit breaker operation. Additionally, it has good fire and abnormal heat resistance, passing the 650℃/30s fire resistance test (per IEC 60529-1), providing a reliable safety barrier under extreme thermal conditions.

3. Precise Dimensions & User-Friendly Design
The enclosure has compact dimensions: 230mm (length) × 90mm (width) × 78.3mm (depth). A transparent observation window (76.3mm × 62.65mm) is embedded, allowing direct visual inspection of the circuit breaker’s working status without opening the box. Its simplified structure enables easy installation and maintenance, streamlining circuit breaker deployment and routine checks.

4. Core Application & Value
Designed specifically for installing and protecting circuit breakers, this series is widely used in residential, commercial, and small industrial low-voltage distribution scenarios. It offers a standardized, safe solution for international power distribution projects, efficiently meeting diverse operational and safety requirements.
