Overcurrent circuit breaker series 15kA 1+N-pole FAZ-B6/1N 278642

1+N-Pole Overcurrent Circuit Breaker – Reliable Installation Protection

This FAZ series overcurrent circuit breaker, with a rated current of 6A, is a key element ensuring safety in every electrical installation. Designed to protect circuits from overload and short circuit, it performs well in both domestic and professional applications. The breaking capacity of up to 15kA (according to IEC/EN 60947-2) guarantees an effective response in emergency situations, minimizing the risk of damage and fire. The 1+N design allows for simultaneous disconnection of the phase and neutral, which increases safety.

Characteristics and application

The circuit breaker is characterized by a B characteristic, which means it is ideal for circuits with devices with high inrush current – e.g. motors or transformers. Thanks to this, it does not switch off unnecessarily during short-term voltage surges, but at the same time effectively reacts to overloads. A width of 2 modules makes it easy to install in standard distribution boards. It can be used to protect lighting, socket outlets and other electrical energy consumers.

• Breaking capacity: 15 kA at 400V (IEC 60947-2) and 10 kA at 230V and 400V (EN 60898) – ensures effective protection even with high short-circuit currents.
• B characteristic: ideal for circuits with devices with high inrush current, minimizes the risk of false tripping.
• Mounting: on TH35 rail – quick and easy mounting in standard distribution boards.
• Protection class IP20: protection against touching with a finger and solid objects larger than 12.5 mm.
• Wire cross-section: possibility of connecting solid and stranded wires with a cross-section from 1 to 25 mm² – provides flexibility in choosing wires.
• Operating temperature: wide range of ambient temperatures (-25°C to +75°C) – enables operation in various environmental conditions.

Construction and parameters for professionals

The FAZ-B6/1N circuit breaker has been designed with durability and reliability in mind. Energy limitation class 3 and rated insulation voltage Ui of 440V guarantee safe operation in demanding conditions. Rated impulse withstand voltage Uimp at 4kV provides resistance to transient overvoltages. Additionally, the possibility of additional equipment allows you to adapt the circuit breaker to specific installation needs. It is worth noting the compliance with EN 60898 and IEC/EN 60947-2 standards, which confirms its high quality and safety of use.
