Overcurrent circuit breaker, 2P, C characteristic, 0.5A, 10kA, AC/DC | S202M-C0.5UC 2CDS272061R0984

Protection of installations and devices – reliable ABB S202M-C0.5UC circuit breaker

This two-pole circuit breaker from ABB, with C characteristic and a rated current of 0.5A, is a key element ensuring safety in every electrical installation. Designed to protect circuits against overloads and short circuits, it performs well in both domestic and industrial applications. The short-circuit breaking capacity of up to 10kA (AC/DC) guarantees an effective response in emergency situations, minimizing the risk of damage and fires.

This circuit breaker is compatible with AC and DC installations, increasing its versatility. Its compact design – occupying 2 modules – makes it easy to mount in electrical switchboards with limited space. The use of characteristic C means that the circuit breaker allows for short-term overloads that may occur during the starting of devices with motors or other inductive elements, without unnecessarily disconnecting the circuit.

Construction and application

The S202M-C0.5UC circuit breaker has been designed with durability and reliability in mind. Its housing made of high-quality materials provides resistance to mechanical damage and external factors. Designed to operate at temperatures from 0 to 55°C, it meets the requirements of many different installation environments. The possibility of connecting multi-wire conductors with a cross-section from 0.75 to 25 mm² and solid conductors from 0.75 to 35 mm² provides flexibility in selecting conductors tailored to specific needs. The degree of protection IP20 protects against accidental contact and the ingress of solid objects larger than 12.5 mm.

Circuit breakers of the S202M series are widely used in:

• Lighting

• Electrical outlets

• Heating circuits

• Home automation installations

• Electrical switchboards in residential and commercial buildings

• Industrial applications requiring reliable short-circuit protection

Key features and benefits

• High short-circuit breaking capacity: 10kA (AC/DC) ensures a quick and effective response in the event of a failure.

• C characteristic: ideal for circuits with inductive devices (motors, transformers), allowing for short-term overloads without unnecessary disconnection of the circuit.

• Voltage universality: Operation in both AC and DC circuits increases the range of applications.

• Compact dimensions: occupies only 2 modules in the switchboard, saving valuable space.

• Wide range of conductor cross-sections: allows connection of conductors of different thicknesses (multi-wire and solid).

• Compliance with standards: meets the requirements of EN 60898 and IEC 60947-2 standards, guaranteeing safety of use.

• Energy limitation class: 3 provides adequate protection against the effects of electric arc during short-circuit switching.
