Overcurrent circuit breaker, 1P, Z characteristic, 0.5A, 10kA, AC/DC | S201M-Z0.5UC 2CDS271061R0158

Reliable protection of electrical installations with ABB S201M-Z0.5UC circuit breaker

This single-pole circuit breaker, with a rated current of 0.5A and Z characteristic, is a key element ensuring safety in every electrical installation. Designed by the renowned company ABB, it guarantees effective protection against overloads and short circuits, minimizing the risk of damage to equipment and fires. It is ideal for both new installations and modernization of existing ones.

Functionality and technical parameters

The S201M-Z0.5UC circuit breaker is characterized by a high short-circuit breaking capacity – up to 10kA at 230V and 400V (according to EN 60898 standard). The Z characteristic ensures a quick response to current increase, which is particularly important in circuits with electronic devices sensitive to overvoltage. The possibility of mounting additional accessories expands the functionality of the circuit breaker, adapting it to individual installation needs.

This circuit breaker is perfect for protecting circuits with low power consumption thanks to the precise rated current of 0.5A. The Z characteristic guarantees fast tripping in the event of short circuits, protecting sensitive electronic devices. The high short-circuit breaking capacity (10kA at 230V and 400V according to EN 60898 standard) ensures effective protection even in the event of large overvoltages. Universal application in various types of installations enables a rated voltage of 230V AC/DC. Compact dimensions – 1 module width – allow for efficient use of space in the switchgear cabinet. The degree of protection IP20 provides protection against finger contact, guaranteeing safety of use. A wide range of wire cross-sections – from 0.75 mm² to 35 mm² for solid wires and from 0.75 mm² to 25 mm² for stranded wires – makes it easy to adapt to different types of wires.

Installation and application

The S201M-Z0.5UC circuit breaker is designed for mounting on a TH35 rail (standard mounting rail). Its compact size (installation depth 69 mm) makes installation easy even in tight switchgear cabinets. It will be used to protect lighting circuits, socket circuits and other electrical devices with low power consumption, where a quick response to a short circuit is required (Z characteristic). Energy limitation class 3 provides additional safety in the event of an electric arc during a short circuit.
