What is a residual current circuit breaker (RCC)?
An RCC detects imbalances in current (earth faults) and trips to disconnect power, protecting personnel from electric shock and preventing fire hazards caused by insulation failures.
What is the difference between RCC and standard circuit breaker?
Standard breakers protect against overload and short circuits. RCCs additionally detect earth faults and provide personnel protection by sensing leakage currents as small as 30mA.
What does the 315A rating mean?
The breaker can handle continuous currents up to 315 amperes before tripping due to overload, making it suitable for large three-phase industrial loads.
Is this suitable for single-phase applications?
The QOB315GFI is a 4-pole breaker designed for three-phase 400V systems with neutral. It provides comprehensive protection for three-phase industrial circuits.
What is the typical trip current sensitivity?
RCCs typically trip at 30mA (Class A) for personnel protection, though actual sensitivity depends on the specific model variant and installation configuration.
How does this integrate with Acti 9 panels?
The QOB315GFI uses standard DIN rail mounting and is fully compatible with Schneider Electric's Acti 9 modular distribution board system for seamless panel integration.
