Overcurrent circuit breaker, 2P, Z characteristic, 20A, 6kA, AC | S202-Z20 2CDS252001R0488

Overcurrent circuit breaker from the S200 series is a reliable protection for electrical installations against overloads and short circuits. Designed with safety and durability in mind, it will work well in both home and commercial installations. This two-pole circuit breaker with a rated current of 20A and characteristic Z provides effective protection for electrical circuits.

Protection and functionality

Characteristic Z means that this circuit breaker is designed to protect circuits with high starting currents – it is therefore ideal for protecting devices with electric motors, transformers or other loads generating current pulses during start-up. The rated short-circuit breaking capacity of 6kA at 400V guarantees a quick response in the event of a failure, minimizing the risk of damage and fire. Additionally, the circuit breaker meets the requirements of overvoltage category III and pollution degree 3, making it suitable for operation in harsh environmental conditions.

Installation and compatibility

The S202-Z20 circuit breaker occupies 2 modules on a DIN rail, which facilitates its installation in electrical switchboards. The possibility of connecting wires with a cross-section from 0.75 mm² to 35 mm² (solid) or from 0.75 mm² to 25 mm² (stranded) ensures wide compatibility with various types of installations. The housing with a degree of protection IP20 protects against accidental contact, but is not resistant to water – therefore, the circuit breaker should be mounted in dry and well-ventilated places. Power losses of 4.8W are typical for this type of device and should not significantly affect the energy efficiency of the installation.

Additional information for professionals

This circuit breaker has energy limitation class 3, which means that it can withstand significant short-circuit energies without damage. The rated impulse withstand voltage Uimp is 4kV, which provides additional safety in the event of atmospheric overvoltages or other disturbances in the electrical network. The possibility of using additional equipment allows you to adapt the functionality of the circuit breaker to the specific needs of a given installation. Compliance with EN 60898 and IEC 60947-2 standards guarantees a high level of safety and reliability of the device.
