5SP4391-7
The 5SP4391-7 features a three-pole, 100A, C-curve design, coupled with a thermomagnetic trip mechanism and a 10kA breaking capacity, making it suitable for overload and short-circuit protection requirements of motors and general inductive load circuits.
Product Positioning
The 5SP4391-7 is a three-pole auxiliary protection circuit breaker from the Siemens SENTRON 5SP4 series. It has a rated current of 100A and C-curve operating characteristics, making it suitable for overload and short-circuit protection in general industrial distribution boxes.
Core Product Advantages and Features
Tri-polar design
With a 3P pole configuration, it can simultaneously protect three-phase circuits and is suitable for three-phase power distribution applications.
C-curve jump
The magnetic tripping action range is 5 to 10 times the rated current, suitable for general inductive loads and motor circuits.
Thermomagnetic composite protection
Combining thermal overload protection and magnetic instantaneous short-circuit protection, dual protection provides greater peace of mind.
DIN rail mounting
Standard 35mm DIN rail quick-release installation, convenient and time-saving for distribution box construction.
