Siemens 4P 40A 10KA Circuit Breaker 4M B 5SL44406

The circuit breaker is an ideal protective device for residential and commercial electrical systems. Designed to automatically interrupt current flow in the event of an overload or short circuit.

 

The trip curve B makes it suitable for protecting circuits with normal loads. Easy to install, it occupies four modules and provides reliable and safe protection.

 

The trip curve B of a circuit breaker is designed to intervene quickly in the event of an overload or short circuit, protecting circuits with normal loads, such as those found in residential or commercial installations. Here are the main features:

• Magnetic trip: Triggers when the current exceeds 3 to 5 times the rated current
• Common use: Circuits with resistive loads, such as lights or small appliances
• Fast tripping time: Ideal for protection of electronic devices sensitive to overcurrents
