JUNW PG 2P 4P Residual Current French Differential Circuit Breaker with Integral Overcurrent Protection

PG Series Circuit Breakers with Integral Overcurrent Protection
1. Core Parameters & Upgraded Integrated Protection
Suitable for AC 50Hz, 250/440V power circuits, the PG Series circuit breakers adopt an upgraded protection design, combining overload protection, short-circuit protection and newly added earth leakage protection into one unit. With a rated current range of 5A to 60A, it delivers all-round fault protection for residential and commercial power systems.
2. Wiring Modes & Adjustable Leakage Sensitivity
It supports both 1 Ph + N (single-phase with neutral) and 3 Ph + N (three-phase with neutral) wiring modes to fit diverse installation needs. The newly added earth leakage protection provides three optional sensitivity levels (300mA, 500mA, 650mA), offering customized safety protection for different electrical environments.
3. New Enclosure Design with Leakage Test Button
A newly added earth leakage test button is equipped on the outer shell, allowing users to manually simulate earth leakage faults for quick function verification. This user-friendly design simplifies routine safety checks and ensures the leakage protection module works reliably at all times.
4. Application Scenarios & Safety Upgrade
As a key connecting device between power grid utilities and end-users, it realizes stable access to public distribution networks. The addition of earth leakage protection greatly improves electrical safety, making it a cost-effective and reliable choice for standard household and commercial service connection.
5. Compliance & Structural Advantages
All performance and design specifications fully meet the French NFC 61450 standard. The neutral pole features a first-close & last-open structure to maintain stable potential during operation, while the professional anti-surge design resists atmospheric voltage surges and ensures uninterrupted power supply.
6. Comprehensive Safety Defense
The upgraded three-in-one protection system effectively prevents overload, short-circuit and electric shock risks caused by earth leakage. It builds a full-scale safety barrier for electrical equipment and personal use, greatly enhancing the reliability of the entire power system.
