1.Introduction
A residual current circuit breaker is a core safety protection device in electrical systems, serving as an electrical switch with residual current protection (and over current/short-circuit protection for select models).
2.Types and Practical Applications
①RCCB:Requires work with a separate MCB
Typical Scenarios: Industrial equipment power circuits, building distribution mains.
②RCBO:To simplify circuit layout (avoids dual installation of RCCB + circuit breaker).
Typical Scenarios: Residential/apartment socket circuits, commercial store distribution, independent circuits for small industrial equipment (e.g., electrical tools, precision instruments).
3.Usage Scenarios
Residential: Bathrooms (moist environments), socket circuits, high-power appliances (e.g., air conditioners).
Industrial: Production equipment (e.g., machine tools, motors), moist/dusty work areas, temporary power supplies.
