SZ201-B50 overcurrent circuit breaker, 1P, B characteristic, 50A, 6kA, AC 2CDS251025R0505

Reliable protection of electrical installations – ABB SZ201-B50 circuit breaker

This single-pole circuit breaker from ABB's SZ200 series is a key element ensuring safety in every electrical installation. Designed to protect against the effects of overloads and short circuits, it guarantees reliable operation and peace of mind for both installers and end-users. Characteristic B makes it ideal for circuits with devices with high inrush current, such as motors or transformers.

Solid construction and universal application

The SZ201-B50 circuit breaker is characterized by its compact dimensions – it occupies only one module on the DIN rail (width 18.1 mm). Its housing made of high-quality materials ensures durability and resistance to mechanical damage. Adapted to work in a wide temperature range (from -25°C to 55°C) it will perform well in various environmental conditions. The possibility of connecting wires with a cross-section from 0.75 mm² to 35 mm² (solid) or 0.75 mm² to 25 mm² (stranded) provides flexibility during installation.

Safety confirmed by standards

The circuit breaker meets the requirements of EN 60898-1 standard, which guarantees its compliance with the highest safety standards. The rated short-circuit breaking capacity Icn is 6 kA at both 230 V and 400 V, ensuring effective circuit protection in the event of a failure. Energy limitation class 3 and overvoltage category III further increase the safety level of the installation. Protection degree IP20 protects against accidental contact.
