Overcurrent circuit breaker, 3P, C characteristic, 3A, 6kA, AC | S203-C3 2CDS253001R0034

Reliable protection of electrical installations with S200 series circuit breaker

This three-pole circuit breaker with C characteristic is a key element of every safe and reliable electrical installation. Designed to protect against overloads and short circuits, it provides peace of mind for both installers and end users. A rated current of 3A combined with a short-circuit breaking capacity of 6kA (AC) makes it an ideal choice for protecting circuits with moderate loads.

Functionality and parameters tailored to your needs

The S203-C3 circuit breaker is characterized by its versatility and ease of mounting on a DIN rail. A width of 3 modules allows for efficient use of space in the switchgear cabinet. The C characteristic provides a delayed tripping response to short-term overloads, which is particularly important for devices with motors or other elements generating high starting currents – avoiding unnecessary tripping of the circuit when starting devices. The rated insulation voltage Ui of 440V and overvoltage category III guarantee safety even in difficult operating conditions.

• Wide connection range: The ability to connect solid core wires from 0.75 mm² to 35 mm² and stranded wires from 0.75 mm² to 25 mm² ensures compatibility with various types of installations.
• Resistance to environmental conditions: The circuit breaker retains its properties in a wide range of ambient temperatures, from -25°C to 55°C, making it suitable for indoor applications.
• Compliance with standards: Energy limitation class 3 and high short-circuit breaking capacity (Icn 6kA at 400V, Icu 10kA at 400V according to IEC 60947-2) confirm its compliance with applicable safety standards.
• Expandability: Compatibility with additional equipment allows you to adapt the functionality of the circuit breaker to the specific needs of the installation.
• Durable construction: Protection class IP20 provides basic protection against contact and ingress of solid objects, and power losses of only 3.9W minimize the impact on the energy efficiency of the installation.
