Overcurrent circuit breaker, 3P+N, B characteristic, 16A, 6kA, AC | S203-B16NA 2CDS253103R0165

Overcurrent circuit breaker from the S203 series is a reliable solution for protecting electrical installations against overloads and short circuits. Designed for use in residential, commercial and industrial buildings, it ensures the safety of people and equipment. This model, with a rated current of 16A and B characteristic, is ideal for circuits requiring a quick response to current increase, while tolerating short-term load surges – for example, when starting motors.

Features and application

This three-pole plus neutral pole (3P+N) circuit breaker, with a width of 4 modules, is mounted on a TH35 rail. Its compact dimensions (installation depth 69 mm) allow for easy installation even in limited space of the switchgear. Short-circuit capacity of 6kA at 230/400V AC guarantees effective disconnection of the circuit in the event of a failure. Made of high-quality materials, it meets stringent safety standards and ensures long-term reliability. The cross-section of solid wires from 0.75 to 35 mm² and stranded wires from 0.75 to 25 mm² provides great flexibility when selecting cables.

Advantages and benefits

• Versatile application: Suitable for protecting lighting circuits, socket circuits and other electrical loads.
• B characteristic: Provides a quick response to current increase, protecting against damage caused by overload or short circuit – particularly important in circuits with electronic receivers.
• High short-circuit capacity: 6kA ensures effective disconnection of the circuit in the event of a serious failure, minimizing the risk of damage and fire.
• Easy installation: Mounting on a TH35 rail is quick and easy, which translates into time savings during installation.
• Safety: Compliance with IEC/EN 60898-1 and IEC/EN 60947-2 standards guarantees a high level of safety.
• Durability: Made of high-quality materials ensures long-term reliability and resistance to environmental conditions (operating temperature from -25°C to +55°C).
• N protection: The presence of a disconnectable N pole increases the safety of the installation, allowing for complete disconnection of the circuit in the event of a failure.

This circuit breaker is a solid choice for both professional installers looking for reliable protection for their customers, and for end-users who care about the safety of their home electrical installation.
