5SL6401-7RC
The 5SL6401-7RC is a 4-pole (3P+N) miniature circuit breaker from the Siemens SENTRON 5SL6 series. It has a rated current of 1A, a C-type operating curve with a high breaking capacity of 7.5kA, and adopts an SLR quick-release design, making installation and maintenance more time-saving and labor-saving.
Product Positioning
The Siemens SENTRON 5SL6401-7RC is a 4-pole (3P+N) miniature circuit breaker with a rated current of 1A, a type C operating curve, and a breaking capacity of up to 7.5kA. It is suitable for branch protection in three-phase four-wire power distribution systems.
Core Product Advantages and Features
SLR quick-release installation design
The exclusive SLR sliding latch mechanism allows for tool-free installation and removal from the DIN rail, reducing the time required for switchboard maintenance and replacement.
Halogen-free and silicon-free material construction
The main body is made of halogen-free and silicon-free materials, and the smoke toxicity is low when it is burned in a fault, which meets the fire prevention and environmental protection requirements of modern distribution boxes.
7.5kA high trip rating
With a breaking capacity of 7.5kA, it provides a higher short-circuit protection margin than the standard model, making it suitable for power distribution applications with high short-circuit current or low line impedance.
3P+N quadripolar architecture
The 4-pole (3P+N) design covers both the three-phase and neutral circuits, allowing one unit to complete the full protection of a three-phase four-wire branch circuit.
C-shaped motion curve
It trips instantaneously at 5 to 10 times the rated current, and is suitable for general lighting, sockets and load circuits with medium starting current.
