The WRO1-63 1P+N is an advanced Residual Current Circuit Breaker with Integral Overcurrent Protection (RCBO) that also features integrated overvoltage protection, making it a comprehensive safety solution for single-phase applications.
Key Features:
4-in-1 Comprehensive Protection: Integrates overload protection, short-circuit protection, earth leakage protection, and overvoltage protection in a single compact module, saving valuable panel space.
Adjustable Residual Current Sensitivity: Available in three sensitivity options (30mA for personnel protection, 100mA for combined protection, 300mA for fire prevention) to match specific application requirements.
Integrated Overvoltage Protection: Safeguards connected equipment against dangerous voltage surges and fluctuations, preventing damage to sensitive electronics and appliances.
Compact 1P+N Design: Space-saving single-module width design, ideal for use in standard distribution boards where space is limited.
Applications:
Residential Electrical Panels
Home Office & Sensitive Electronics
