Reliable protection of electrical circuits – ABB S200 series circuit breaker

This single-pole ABB circuit breaker from the S200 series is a compact and efficient solution for protecting electrical installations in residential, commercial and industrial buildings. Designed to protect against overloads and short circuits, it ensures the safety of people and property, and also enables circuit control. Characteristic B makes it ideal for circuits with inductive or capacitive loads, where short-term current surges occur – for example, when starting motors.

This circuit breaker is characterized by a rated current of 4A and a short-circuit breaking capacity of up to 6kA at 230V and 10kA at 400V. This ensures effective protection against the effects of failures, minimizing the risk of damage and fires. Mounting on a TH35 rail allows for quick and easy installation in the switchgear cabinet. Compact dimensions – 1 module wide – allow you to save space in the switchgear cabinet.

Design and application

S200 series circuit breakers are designed to operate in TN and IT systems, offering versatile applications. The cross-section of the connecting wires from 0.75 mm² to 25 mm² (multi-stranded) and 0.75 mm² to 35 mm² (solid) ensures compatibility with various types of wires. The degree of protection IP20 guarantees protection against accidental contact, which is important for safety. The circuit breaker is designed to operate in ambient temperatures from -25°C to +55°C, making it suitable for use in various environmental conditions.

Advantages and benefits
