Overcurrent circuit breaker, 3P, C characteristic, 16A, 25kA, AC | S303P-C16 2CDS383001R0164

S303 Series Circuit Breakers – Reliable Installation Protection

This three-pole circuit breaker with C characteristic is a key element of every safe and efficient electrical installation. Designed to protect circuits against overloads and short circuits, it provides reliable operation in homes, commercial and industrial buildings. The S303P-C16 model combines compact dimensions with high performance, making it an ideal choice for both professional installers and demanding end-users.

Functionality and technical parameters

The circuit breaker is characterized by a rated current of 16A and a short-circuit breaking capacity of up to 25kA at 400V. The C characteristic provides a delayed tripping, which is particularly important for loads with high inrush currents, such as motors or transformers. This prevents the circuit breaker from tripping unnecessarily during short-term current surges, while effectively responding to overloads and short circuits, protecting wires and devices. A width of 3 modules allows for efficient use of space in the distribution board.

• Overload and short-circuit protection: Protects the electrical circuit from damage caused by excessive current.
• C characteristic: Delayed tripping ideal for devices with high inrush current (e.g., motors, transformers).
• Short-circuit breaking capacity 25kA: Ensures effective circuit interruption in the event of a short circuit.
• TH35 rail mounting: Standard mounting simplifies installation and replacement.
• Width 3 modules: Compact dimensions save space in the distribution board.
• Rated voltage 415V: Universal application in various electrical installations.
• Wire cross-section 0.75 - 25 mm²: Allows connection of wires of different thicknesses.

Construction and application

The S303P-C16 circuit breaker is made of high-quality materials, guaranteeing its durability and reliability. The housing made of temperature-resistant plastic ensures safe use, and the possibility of sealing the switching lever prevents accidental or unauthorized switching on/off. This circuit breaker finds application in a wide range of electrical installations:

• Home installations: Protection of lighting, socket circuits and household appliances.
• Commercial buildings: Protection of electrical installations in offices, shops or warehouses.
• Industry: Protection of production machines and equipment against overloads and short circuits.
• Main and sub-distribution boards: Installation inside electrical distribution boards as an element of the overvoltage and short-circuit protection system.
