Overcurrent circuit breaker, 1P, C characteristic, 4A, 10kA, AC | SU201M-C4 2CDS271337R0044

Reliable protection for your electrical installation

This single-pole circuit breaker with C characteristic is a key element in protecting electrical circuits. It provides effective protection against overloads and short circuits, protecting both devices and the installation. It is ideal for securing lighting circuits, socket circuits and devices with a characteristic starting current, such as motors or transformers.

Functionality and parameters

This circuit breaker is characterized by a rated current of 4A and a short-circuit breaking capacity of up to 10kA at AC voltage. The C characteristic means that the circuit breaker reacts faster to overloads, but is more tolerant to short-term current surges – which is particularly important when connecting devices with motors or other elements generating high starting current. The rated impulse withstand voltage of 4kV provides additional safety in the event of overvoltage. The compact design (1 module width) allows for efficient use of space in the distribution board.

Installation and application

The circuit breaker is mounted on a standard DIN rail, which simplifies and speeds up installation. Designed to operate at temperatures from -25°C to 55°C, making it suitable for use in various environmental conditions. The possibility of using wires with a cross-section from 0.75 mm² to 25 mm² provides flexibility in choosing wires tailored to specific needs. Compliance with EN 60898 and IEC 60947-2 standards guarantees safety and reliability of operation. Energy limitation class 3 indicates its ability to limit short-circuit energy, minimizing potential damage to the installation and connected devices.
