Here’s a refined version of the product description for the Type B Residual Current Circuit Breaker (RCCB):
Comprehensive AC/DC DetectionThis Type B RCCB not only detects normal alternating current (AC) but also high-frequency AC and even small direct current (DC) residual currents, making it highly versatile and reliable. It is particularly approved for use in wall boxes and charging stations.
High Switch-Off Capacity & Enhanced SafetyWith a pin sensitivity of 30 mA and a high switch-off capacity of up to 10 kA, this RCCB offers strong protection. It features a protective cover over the internal screws, ensuring insulation and sealing functions. The integrated display window also allows for easy identification of RCCB errors.
Optimal Fire and Shock PreventionType B RCCBs are capable of detecting both high-frequency AC and pure DC residual currents, significantly reducing the risk of fires and electric shocks through automatic shutdown of the power supply. Selecting the appropriate type of RCCB is crucial to ensuring this enhanced level of protection.
Wide Application & FunctionalityDesigned for controlling circuits, it protects individuals from indirect touch and provides additional protection against direct touch. It also safeguards systems from fire hazards due to insulation defects. Commonly used in residential buildings, industrial sectors, and EV/PV systems, this RCCB is ideal for frequency converters, UPS systems, high-frequency power converters, and construction power supply cabinets.
