5SP4380-8
The 5SP4380-8 is a three-pole, 80A specification circuit with a D-curve design and a high magnetic tripping range, suitable for protection requirements of high surge current circuits such as transformers and large motor starting circuits.
Product Positioning
The 5SP4380-8 is a three-pole auxiliary protection circuit breaker from the Siemens SENTRON 5SP4 series, with a rated current of 80A and D-curve operating characteristics. It is specifically designed for circuits with high surge starting current.
Core Product Advantages and Features
Tri-polar design
3P pole configuration, suitable for overload and short circuit protection of three-phase power circuits.
D curve jump
The magnetic tripping operation range is 10 to 20 times the rated current, suitable for high surge loads such as transformers and capacitors.
Thermomagnetic composite protection
Combining thermal overload and magnetic instantaneous short circuit protection mechanisms
DIN rail mounting
Standard 35mm DIN rail quick-release clips make electrical box installation and maintenance more time-saving.
