Product Description
Circuit Breaker Overview
Circuit breakers are designed to close, carry, and interrupt current under normal circuit conditions, and to close, carry, and interrupt current under specified abnormal circuit conditions. These devices are categorized as high-voltage circuit breakers (above 3 kV) and low-voltage circuit breakers based on their application voltage range.
PG Series Circuit Breakers
Available in current ratings from 5A to 60A, with configurations for (1 phase + neutral) or (3 phases + neutral), with or without differential protection (300mA, 500mA, or 650mA).
Operating Principles
- Service connections serve as the interface between utility power and end-user installations
- Connect customer electrical installations to the electrical distribution network
Key Advantages
- Cost-effective solution for conventional service connections
- Multiple classification device options
- Various ground leakage sensitivity levels
- Compliant with French NFC 61450 standard
Easy Operation Features
- Operational in all mounting positions
- ON/OFF control via push-button with easily modified rating
- Sealable terminal covers
- Non-losing terminal screws
- Rotating terminals
- Copper cables up to 35 mm² capacity
- Neutral terminal identified in blue
Safety Features
- Thermal compensation for stable performance
- Pole settings unaffected by ambient temperature
- Self-powered residual current device
- Highly reliable system immune to atmospheric overvoltages
- Uninterrupted power supply for enhanced convenience
- Overvoltage prevention
- Neutral pole designed to close first and open last for fixed potential maintenance
