Overcurrent circuit breaker, 3P, B characteristic, 16A, 25kA, AC | S303P-B16 2CDS383001R0165

Three-pole overcurrent circuit breaker with B characteristic – reliable installation protection

This three-pole circuit breaker from the S300P series by ABB is a key element of every safe and efficient electrical installation. Designed to protect circuits against overload and short circuit, it provides effective protection in both commercial and industrial applications. The S303P-B16 circuit breaker with a rated current of 16A and a short-circuit breaking capacity of 25kA is a solid solution for installers and users looking for reliability and safety.

Functionality and application

Equipped with a B characteristic, this circuit breaker reacts quickly to short circuits while tolerating brief current surges during the start-up of devices with motors – making it an ideal choice for circuits powering inductive loads. Its wide operating temperature range (from 0 to 70°C) and the possibility of mounting on a DIN rail ensure installation flexibility in various environmental conditions. The circuit breaker is a direct replacement for the older S203P-B16 model, making it easier to modernize existing installations.

Advantages and design features

• High short-circuit breaking capacity: 25kA guarantees effective disconnection of the circuit in the event of a short circuit, minimizing the risk of damage and fire.
• B characteristic: Provides a quick response to short circuits while allowing the starting of devices with motors without unnecessary tripping.
• Wide connection range: The possibility of connecting solid wires with a cross-section from 0.75 to 35 mm² and stranded wires from 0.75 to 25 mm² ensures compatibility with various types of wires.
• Compact dimensions: A width of only 3 modules allows for efficient use of space in the switchgear cabinet.
• Durable construction: Made of high-quality materials, it ensures long life and reliable operation.
• Compliance with standards: Meets the requirements of IEC 60947-2 and EN 60898 standards, guaranteeing safety and compliance with regulations.
• Rated voltage: Suitable for operation at 415V AC/DC, which increases its versatility.
• Protection degree IP20: Provides protection against touching fingers and against the ingress of solid objects larger than 12mm.

The S303P-B16 circuit breaker is not only a protective element but also an investment in safety and peace of mind. Its solid construction and high quality of workmanship guarantee long-term and trouble-free operation in demanding working conditions.
