The ABB S203-C16 is a high-quality miniature circuit breaker designed to provide efficient and reliable overcurrent protection. Engineered for use in a variety of residential, commercial, and industrial applications, this three-pole circuit breaker features a C tripping characteristic, ensuring a quick response to short circuits and overload conditions.
With a rated current of 16 A and an operational voltage of 400 V AC, the S203-C16 is capable of handling a diverse range of electrical loads. Its compact dimensions of 52.5 x 69 x 88 mm allow for space-saving installation on standard DIN rails, making it a versatile choice for electrical distribution systems.
The breaker is crafted to comply with international standards, including IEC/EN 60898-1 and IEC/EN 60947-2, as well as North American standards UL1077 and CSA 22.2 No. 235. This ensures its suitability for global use and underscores its commitment to safety and quality.
The S203-C16's thermal/electromechanical tripping mechanism provides dual protection, with a delayed thermal response for overload scenarios and an immediate electromechanical response for short-circuit incidents. This dual mechanism ensures that circuits are safeguarded against a wide range of fault conditions.
Additionally, the circuit breaker's screw terminal connections offer a secure and reliable means of wiring, while the toggle actuator type provides clear and intuitive control. The device also features an energy limiting class of 3, which contributes to the overall safety of the electrical system by limiting the energy let-through in the event of a fault.
Overall, the ABB S203-C16 miniature circuit breaker is a dependable and efficient solution for protecting electrical circuits from overcurrents, ensuring the safety and longevity of electrical installations.
