## Long description

The ABB SZ203-C16 is a high-performance 3-pole miniature circuit breaker engineered to provide robust electrical protection for residential and commercial distribution systems. This device is designed to monitor electrical circuits and automatically disconnect power in the event of an overload or short circuit, thereby preventing damage to wiring and connected equipment. Built to meet rigorous safety standards, this circuit breaker offers reliable operation and long-term durability in various electrical installations.
Advantages
This miniature circuit breaker stands out due to its high-quality construction and precise tripping characteristics. The C-curve design makes it particularly effective for applications with moderate inrush currents, ensuring that the breaker does not trip unnecessarily during normal operation while still providing rapid response times during genuine fault conditions. Its compact 3-pole design allows for efficient space utilization in distribution boards, and the robust terminal connections ensure a secure and stable electrical contact over the entire service life of the device.
Suitable for
Residential electrical distribution boards
Commercial building power systems
Protection of lighting circuits
Control circuits for small motors and appliances
This circuit breaker may not be suitable for applications requiring a different tripping characteristic, such as B-curve for long cable runs or D-curve for high-inrush loads like large transformers. It is also not intended for use in environments exceeding its specified voltage or current ratings.
Key specifications
Number of poles: 3
Rated current: 16A
Breaking capacity: 6kA
Tripping characteristic: C-curve
Mounting type: DIN rail
The device should be installed by a qualified professional in accordance with local electrical regulations. It is designed for mounting on a standard DIN rail within a distribution enclosure. Ensure that the supply voltage matches the device specifications and that all terminal screws are tightened to the recommended torque to prevent overheating or loose connections.
What to consider before purchase
Verify the required current rating for your specific circuit
Ensure the 3-pole configuration matches your electrical system requirements
Check the available space in your distribution board
Confirm that the C-curve characteristic is appropriate for your connected loads
For optimal safety and performance, regularly inspect the circuit breaker for signs of wear or damage and ensure that the distribution board is kept free of dust and moisture. Do not attempt to modify or repair the internal mechanism of the device.
