Overcurrent circuit breaker, 3P, C characteristic, 13A, 10kA, AC | S203M-C13 2CDS273001R0134

Reliable protection of electrical installations – ABB S203M-C13 circuit breaker

This three-pole circuit breaker from ABB with characteristic C is a key element ensuring safety in every electrical installation. Designed for both domestic and industrial applications, it effectively protects circuits against overloads and short circuits. The rated current of 13A combined with the short-circuit breaking capacity of up to 10kA (at 230V) and 15kA (at 400V) guarantees reliable operation even in demanding conditions.

This circuit breaker, mounted on a DIN rail, occupies only 3 modules in width, allowing for optimal use of space in the distribution board. Its solid construction and high quality workmanship translate into a long service life and trouble-free operation. The use of characteristic C makes the circuit breaker cope well with impulse loads, such as starting motors or devices with heating elements.

Key features and applications

• Versatile application: ideal for protecting lighting circuits, socket circuits and electrical devices with moderate inrush current.
• Overload and short-circuit protection: provides effective protection of the electrical installation and connected devices.
• Characteristic C: allows for short-term overloads without unnecessary tripping, which is particularly important when handling devices with motors or heating elements.
• Short-circuit breaking capacity: high short-circuit breaking capacity (10kA at 230V, 15kA at 400V) ensures safety in the event of serious failures.
• DIN rail mounting: quick and easy mounting on a standard DIN rail.
• Compact dimensions: only 3 modules wide saves space in the distribution board.
• Wide operating temperature range: the ability to operate at temperatures from -25°C to +55°C makes it suitable for various environments.
• Wire cross-sections: accepts solid wires with a cross-section from 0.75 mm² to 35 mm² and stranded wires from 0.75 mm² to 25 mm².

The S203M-C13 circuit breaker meets the requirements of IEC 60947-2 and EN 60898 standards, which confirms its high quality and safety of use. The energy limitation class is 3, which means a good ability to limit short-circuit energy. The rated insulation voltage Ui is 440V and the rated impulse withstand voltage Uimp is as much as 4kV – these parameters guarantee safe operation in various voltage conditions. Power losses are only 6.9W, which translates into energy efficiency of the installation.
