5SP4391-6
The 5SP4391-6 is a three-pole, 100A circuit with a B-curve sensitive trip design and a breaking capacity of 6kA. It is suitable for circuit protection with small surge currents, such as lighting and general resistive loads.
Product Positioning
The 5SP4391-6 is a three-pole auxiliary protection circuit breaker from the Siemens SENTRON 5SP4 series. It has a rated current of 100A and B-curve operating characteristics, and is suitable for protection of general resistive load circuits.
Core Product Advantages and Features
Tri-polar design
3P pole configuration, suitable for overload and short circuit protection in three-phase power distribution circuits.
B curve jump
The magnetic tripping action range is 3 to 5 times the rated current, with high sensitivity, making it suitable for lighting and resistive loads.
Thermomagnetic composite protection
Combining thermal overload protection and magnetic instantaneous short circuit protection mechanisms
DIN rail mounting
Standard 35mm DIN rail quick-clamp installation, convenient for construction and assembly.
