Overcurrent circuit breaker S803P-B100 2CCG001221R0001

Robust protection for electrical installations – ABB S803P-B100 circuit breaker

This three-pole ABB S800 series circuit breaker is a reliable protective element in any electrical installation. Designed for both home and commercial use, it effectively protects circuits from overload and short circuit. Characteristic B provides a quick response to current increase, which is particularly important for inductive and resistive loads. This circuit breaker is ideal for protecting lighting, socket outlets and other electrical devices.

Safety and functionality in one device

The S803P-B100 circuit breaker is distinguished by its high short-circuit breaking capacity – up to 50 kA at 230 V and 400 V (according to IEC 60947-2). This guarantees safety even in the event of serious disturbances in the network. The rated current of 100 A allows you to protect circuits with higher power consumption. In addition, energy limitation class 3 and overvoltage category III provide resistance to interference and damage. Mounting on a TH35 rail allows for easy and quick installation in a distribution board.

Key features for professionals and users

• High short-circuit breaking capacity: 50 kA at 230/400 V – ensures effective protection of the installation against the effects of short circuits.

• Characteristic B: quick response to current increase, ideal for protecting mixed loads (resistive and inductive).

• Three-pole design: protects all phases, providing comprehensive protection.

• Width of 4.5 modules: compact dimensions make it easy to install even in tight distribution boards.

• Wire cross-section: possibility to connect wires with a cross-section from 1 to 70 mm² (solid) and from 1 to 50 mm² (stranded) – provides flexibility in choosing wires.

• Operating temperature: wide operating temperature range (-25°C to +60°C) allows the circuit breaker to be used in various environmental conditions.

• Degree of protection IP20: protection against touching with fingers and solid objects larger than 12.5 mm – ensures safe use.

• Rated impulse withstand voltage Uimp: 6kV - increased resistance to impulse overvoltages.

Thanks to these features, the ABB S803P-B100 circuit breaker is an investment in the safety and reliability of your electrical installation.
