S200 Series Circuit Breakers – Reliable Installation Protection

The S201-B1 circuit breaker is a single-pole protection device designed to protect electrical circuits from overload and short circuit. The device is characterized by high efficiency and durability, making it an ideal choice for both professional installers and end users. Manufactured by the renowned ABB, this circuit breaker meets stringent safety and quality standards.

This model, with a rated current of 1A and B characteristic, is perfect for residential and commercial applications. The B characteristic means that the circuit breaker reacts quickly to short-term current surges, but is more tolerant to momentary overloads, which is particularly important for devices with electric motors or other elements generating high starting currents. The rated short-circuit breaking capacity of 6kA (at 230V) and 10kA (at 400V) ensures effective protection of the installation in the event of a failure.

Construction and mounting

The S201-B1 circuit breaker is mounted on a DIN rail with a width of one module (18mm), allowing for easy integration with existing distribution boards. The compact dimensions (installation depth 69 mm) facilitate installation even in limited space. Connection cables with a cross-section from 0.75 mm² to 25 mm² (multi-strand) or from 0.75 mm² to 35 mm² (solid core) can be connected without additional tools, which significantly speeds up the installation process. The IP20 degree of protection provides basic protection against accidental contact and the ingress of solid objects larger than 12.5mm.

The circuit breaker is designed in accordance with IEC EN 60898 and IEC EN 60947-2 standards, guaranteeing its compliance with applicable regulations and safety standards. The device operates in an ambient temperature range of -25°C to +55°C, allowing its use in various environmental conditions. Additionally, the possibility of mounting additional equipment allows the circuit breaker to be adapted to the specific requirements of a given installation.
