Featuring a C-type tripping characteristic and a 40A rated current, it is suitable for industrial and commercial applications. With a breaking capacity of 20000 A and an operating voltage range of 230-400 V, this device ensures safety against overloads and short circuits in electrical distribution systems.

## Long description

The ABB S203-C40 is a high-performance 3-pole miniature circuit breaker engineered to provide robust protection for electrical circuits in demanding environments. This device integrates advanced thermal and electromechanical tripping mechanisms to effectively safeguard systems against both overloads and short circuits. Designed for reliability, it serves as a critical component in modern electrical distribution systems, ensuring consistent performance and safety for connected equipment.
Advantages
This circuit breaker offers exceptional current-limiting capabilities, which significantly reduce the energy let-through during a fault, thereby protecting downstream components from damage. Its dual-tripping mechanism ensures precise response times for different types of electrical disturbances. The compact design allows for efficient installation within distribution boards, and the ability to mount auxiliary contacts at the bottom helps optimize space usage within enclosures. The device is built to meet stringent international standards, guaranteeing high quality and long-term operational stability.
Suitable for
Industrial electrical distribution systems
Commercial building power management
Protection of motors and lighting circuits with moderate inrush currents
General electrical infrastructure requiring reliable short-circuit protection
This circuit breaker may not be suitable for applications requiring specific tripping characteristics other than Type C, such as highly sensitive electronic equipment that might require Type B or specialized protection. It is also not intended for use in environments exceeding its rated voltage or current specifications, nor should it be used in circuits where the prospective short-circuit current exceeds its rated breaking capacity.
Key specifications
Number of poles: 3
Tripping characteristic: Type C
Rated current: 40A
Operating voltage: 230/400V AC
Breaking capacity: 6 kA
Compliance: IEC/EN 60898-1, IEC/EN 60947-2, UL1077, CSA 22.2 No. 235
How to use
The ABB S203-C40 should be installed by a qualified electrician in accordance with local electrical regulations. It is designed for DIN-rail mounting within a standard distribution board or consumer unit. Ensure that the supply cables are securely connected to the terminals, observing the correct torque settings to prevent loose connections. Once installed, the toggle switch can be used to manually open or close the circuit. In the event of a trip, the handle will move to the center or off position; investigate the cause of the fault before resetting the breaker.
What to consider before purchase
Verify that the 40A rated current matches the load requirements of your circuit.
Ensure the 3-pole configuration is appropriate for your specific power supply system.
Check that the Type C tripping characteristic is suitable for the connected loads, particularly regarding inrush currents.
Confirm that the available space in your distribution board accommodates the physical dimensions of the device.
Usage recommendations: Regularly inspect the circuit breaker for signs of physical damage or overheating. It is recommended to perform periodic functional checks to ensure the tripping mechanism remains operational. Do not attempt to modify or repair the internal components of the device.
