SZ203-C32 circuit breaker, 3P, characteristic C, 32A, 6kA, AC 2CDS253025R0324

Three-pole overcurrent circuit breaker – reliable installation protection

This three-pole circuit breaker from ABB’s SZ203-C32 series is a key element of every safe electrical installation. Designed to protect circuits against overloads and short circuits, it provides reliable operation in homes, commercial and industrial buildings. The C characteristic makes it ideal for circuits with high inrush current, such as motors or heating devices. The rated short-circuit breaking capacity of 6kA guarantees an effective response in emergency situations, minimizing the risk of damage and fires.

Construction and application

The SZ203-C32 circuit breaker is designed for mounting on a DIN rail, which facilitates its installation and replacement. A width of 3 modules allows for efficient use of space in the distribution board. The device meets safety standards, confirming its high quality and reliability. The intended use of this circuit breaker includes protecting circuits with a rated voltage of 400V and a rated current of 32A. Thanks to energy limitation class 3 and overvoltage category 3, the circuit breaker provides adequate protection even in difficult operating conditions.

Key features and benefits

• C characteristic: Provides delayed tripping with short-term overloads, allowing for trouble-free starting of devices with motors or other elements generating high inrush current.
• Short-circuit breaking capacity 6kA: Guarantees effective disconnection of the circuit in the event of a short circuit, protecting against serious damage to the installation and potential fire hazard.
• DIN rail mounting: Enables quick and easy installation and replacement of the circuit breaker without the need to interfere with the wiring.
• Width 3 modules: Optimal use of space in the electrical distribution board.
• Protection degree IP20: Protects against accidental contact and access to live parts.
• Wire cross-section: Accepts solid wires with a cross-section from 0.75 mm² to 35 mm² and stranded wires from 0.75 mm² to 25 mm², providing flexibility when choosing wires tailored to a specific application.
• Operating temperature: The ability to operate in a wide range of ambient temperatures (-25°C to +55°C) ensures reliability in various environmental conditions.

Thanks to these features, the SZ203-C32 circuit breaker is a solid and effective solution for every installer and end-user looking for reliable electrical protection.
