5SP4280-7
The 5SP4280-7 is a bipolar, 80A specification model with a C-curve design and a 10kA breaking capacity. It is suitable for overload and short-circuit protection of motors and inductive loads in two-wire braking force circuits.
Product Positioning
The 5SP4280-7 is a double-pole auxiliary protection circuit breaker from the Siemens SENTRON 5SP4 series. It has a rated current of 80A and C-curve operating characteristics, making it suitable for protection of two-wire distribution circuits.
Core Product Advantages and Features
Bipolar design
2P pole configuration, suitable for overload and short circuit protection in two-wire or single-phase power circuits.
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 mechanisms
DIN rail mounting
Standard 35mm DIN rail quick-release installation, convenient for electrical box construction.
