The RSB-20A Miniature Circuit Breaker with Case is designed for reliable protection and control of low-voltage electrical circuits. With a 20A rated current, this circuit breaker is suitable for electrical distribution systems where dependable protection against overload and short circuits is required.
Product details
Description/Feature/Scope of Application
he RSB series operates at AC 230/400V and is available in 1P, 2P, and 3P configurations, providing flexible options for different circuit arrangements. The 20A rating makes the RSB-20A suitable for a variety of residential, commercial, and industrial electrical applications.
When the current exceeds the safe operating level due to an overload or short circuit, the 20A miniature circuit breaker quickly interrupts the circuit to help protect wiring and connected electrical equipment. The RSB series provides a 3KA breaking capacity and is designed in accordance with IEC 60898 for low-voltage circuit protection.
The RSB-20A features a compact plastic housing and a wired electrical connection. It provides a mechanical life of up to 16,000 operations and an electrical life of up to 4,000 operations, making it suitable for electrical systems that require consistent circuit protection and switching performance.
