Full Product Description
Miniature Circuit Breaker DIN-Rail Mount 1-Pole 20A 3kA C-Curve – CB-AD47M-3120
The CB-AD47M-3120 Miniature Circuit Breaker (MCB) is a compact electrical protection device designed to protect electrical circuits against overcurrent and short-circuit conditions. This 1-pole circuit breaker has a 20A rated current, a 3kA breaking capacity, and a C-curve trip characteristic, making it suitable for a range of residential, commercial and light industrial electrical applications.
The DIN-rail mounting design allows the circuit breaker to be installed easily and securely inside compatible distribution boards, electrical enclosures and control panels. Its compact miniature design makes efficient use of available space while providing convenient circuit isolation and protection.
The C-curve characteristic is commonly used for circuits where moderate starting or inrush currents may occur, such as lighting, general-purpose outlets and certain small electrical equipment. The breaker should always be selected according to the specific circuit, cable rating and electrical installation requirements.
