Overcurrent circuit breaker, 3P, Z characteristic, 2A, 6kA, AC | S203-Z2 2CDS253001R0278

Electrical installation protection with S200 series circuit breaker

This three-pole circuit breaker with Z characteristic is a key element of every safe and reliable electrical installation. It provides effective protection against overloads and short circuits, minimizing the risk of damage and fire. Designed for both home and professional use, it combines compact size with high performance.

Made with attention to detail, this circuit breaker features a solid construction and high-quality workmanship. Mounting on a DIN rail is simple and intuitive, saving time during installation. Its width of 3 modules allows for optimal use of space in the distribution board.

Key features and benefits

• Z characteristic: Provides a quick response to an increase in short-circuit current, which is particularly important in circuits with devices with high inrush current, such as motors.
• Rated current 2A: Ideal for protecting circuits with lower loads, such as lighting or electrical outlets.
• High short-circuit breaking capacity (6kA at 400V): Guarantees safe disconnection of the circuit in the event of a short circuit, protecting both the installation and users. Additional short-circuit capacity Icu at 20kA at 230V and 10kA at 400V provides an additional margin of safety.
• Wide operating temperature range (-25…55°C): Allows installation in various environmental conditions.
• Wire cross-sections from 0.75 to 35 mm²: Provides flexibility in choosing the appropriate wires for a specific application.
• Energy limitation class 3 and surge category III: Provide protection against the effects of overvoltages and voltage surges.
• Protection degree IP20: Protects against finger contact and the ingress of solid objects larger than 12.5 mm – standard for devices mounted inside distribution boards.
• Possibility of additional equipment: Allows to expand the functionality of the circuit breaker according to individual installation needs.

This circuit breaker meets strict safety standards and is a reliable solution for every installer and end user looking for effective protection of their electrical installation. Its compact dimensions (installation depth 69 mm) make it easy to install even in tight spaces. Power losses of 7.5W minimize the impact on the energy efficiency of the system.
