Overcurrent circuit breaker, 2P, Z characteristic, 30A, 10kA, AC | SU202M-Z30 2CDS272337R0528

Electrical installation protection with ABB SU202M-Z30 circuit breaker

This two-pole overcurrent circuit breaker from ABB, with Z characteristic and a rated current of 30A, is a reliable protection for your electrical installation. Designed for both professionals and end-users, it provides effective protection against overloads and short circuits. The Z characteristic means that this circuit breaker is particularly suitable for circuits with inrush currents, e.g. with motors – it allows for short-term exceeding of the rated current without unnecessary tripping of the circuit.

Functionality and technical parameters

The SU202M-Z30 circuit breaker is characterized by a high short-circuit breaking capacity of 10kA, which guarantees safety in the event of serious disturbances in the network. Its width of 2 modules facilitates mounting in standard distribution boards. Designed to operate in installations with a voltage of 440V and a frequency of 50/60Hz, it meets safety standards (overvoltage category III, protection degree IP20). The possibility of mounting additional equipment increases its functionality and adaptation to individual needs. The cross-section of the conductors connected to the circuit breaker can range from 0.75 mm² to 25 mm² (multi-stranded) or 35 mm² (solid), providing great flexibility in cable selection.

Application and benefits

This circuit breaker is used to protect lighting circuits, socket circuits and other electrical receivers in residential and commercial buildings. Its solid construction and high quality workmanship ensure long-lasting and trouble-free operation. Energy limitation class 3 indicates its ability to limit short-circuit energy, which further increases the safety of the installation and devices connected to it. Thanks to this, you can be sure that your installation is protected against the effects of malfunction or failure.
