The Sager Electric RCB-30A Miniature Circuit Breaker is engineered for reliable protection and efficient operation in both residential and industrial electrical systems. With a rated current of 30A, it provides precise overload, short-circuit, and leakage protection, ensuring maximum safety and uninterrupted power distribution.
Product details
Product Overview
A circuit breaker is a helpful device that prevents overload and short-circuit of electrical system. The circuit breakers protect against severe electrical shock or electrocution, mitigate the risk of electrical fires and protect against damaging surges and Voltage spikes. These devices are crucial for switching and shielding your home's wiring from overheating caused by excessive current. The power will be instantly cut off once the flowing current rises above the safe level. Compliant with standards: IEC60898.
Its 30-amp rated capacity makes it ideal for medium-load circuits such as lighting systems, power sockets, HVAC units, and industrial control systems.
Key benefits include:
Accurate tripping characteristics
Easy DIN-rail installation
Flame-retardant housing
High mechanical endurance for long-term use
Main Features and Advantages
