Overcurrent circuit breaker, 2P, C characteristic, 2A, 10kA, AC/DC | S202M-C2UC 2CDS272061R0024

Protection of installations and devices – circuit breaker S202M-C2UC

This two-pole circuit breaker from the S202M-C2UC series by ABB is a reliable safety element in any electrical installation. Designed to protect against the effects of overloads and short circuits, it ensures safety for both the installation and connected devices. Characteristic C makes it ideal for circuits with devices generating inrush currents, such as motors or transformers – it allows it to react more slowly to short current surges, while effectively protecting against long-term overloads.

Versatility and compliance with standards

The S202M-C2UC circuit breaker is compatible with both AC (alternating current) and DC (direct current) installations, making it a versatile solution in various applications. It meets the requirements of IEC/EN 60898-1 and IEC/EN 60947-2 standards, guaranteeing its reliability and safety of use. The ability to extinguish an arc at 10kA at 230V and 15kA at 400V ensures effective protection even in the event of serious disturbances. Energy limitation class 3 further confirms its ability to minimize the effects of short circuits.

Installation and technical parameters

The circuit breaker is mounted on a standard TH35 rail, which facilitates and speeds up installation. Its compact width – only 2 modules – allows for efficient use of space in the switchgear cabinet. The possibility of connecting wires with a cross-section from 0.75 mm² to 35 mm² (solid) or 0.75 mm² to 25 mm² (stranded) provides flexibility in choosing wires tailored to specific needs. The IP20 degree of protection protects against accidental contact, increasing safety of use. The ambient temperature in operating conditions is from 0°C to 55°C, which allows it to be used in a wide range of temperatures. Additionally, the circuit breaker has overvoltage category III and rated impulse withstand voltage Uimp at 4kV.
