5SL6340-7RC
The 5SL6340-7RC belongs to the Siemens SENTRON 5SL6 series. It is a 3-pole C-type miniature circuit breaker with a rated current of 40A and a breaking capacity of 7.5kA. It is an enhanced type and is suitable for the protection of three-phase main circuits with high short-circuit risk.
Product Positioning
The Siemens SENTRON 5SL6 series miniature circuit breakers feature type C tripping characteristics. The 5SL6340-7RC is an enhanced model with a 3-pole 40A and 7.5kA breaking capacity, suitable for three-phase power distribution applications with high short-circuit current.
Core Product Advantages and Features
C-type bounce characteristics
The instantaneous tripping action ratio is approximately 5 to 10 times the rated current, taking into account both the start-up surge and short-circuit protection response speed under normal load conditions.
3-pole (3P) standard design
The three-phase simultaneous operation design allows for the simultaneous disconnection of three-phase power supplies, making it suitable for main switch configurations in three-phase motors or power circuits.
7.5kA breaking capacity
According to IEC 60947-2 standard, the rated breaking capacity is 7.5kA, which is a relatively high specification in the same series and can withstand large short-circuit current impacts.
DIN rail mounting
It adopts standard DIN rail locking for easy and quick installation and subsequent maintenance and replacement in the distribution box.
