Overcurrent circuit breaker series 15 kA 1-pole FAZ-B4/2 278726

Overcurrent circuit breaker FAZ series – reliable installation protection

This two-pole overcurrent circuit breaker from the FAZ series, with a rated current of 4A and B characteristic, is a key element ensuring safety in every electrical installation. Designed by the renowned company Eaton, it offers high effectiveness in protecting against overloads and short circuits. The breaking capacity of up to 15 kA (at 400V) guarantees a quick and reliable response in emergency situations, minimizing the risk of damage and fires.

Construction and application

The FAZ-B4/2 circuit breaker is designed for mounting in electrical distribution boards in residential, commercial and industrial buildings. Its compact dimensions (width of 2 modules) allow for efficient use of space in distribution cabinets. The B characteristic ensures quick tripping in the event of overloads, which is particularly important for circuits with receivers with high inrush current – e.g. electric motors or heating devices. Made of high-quality materials, it ensures long-lasting and trouble-free operation.

Key features and benefits

• High breaking capacity: 15 kA at 400V and 15 kA at 230V according to IEC 60947-2 – ensures effective protection even with high short-circuit currents.
• B characteristic: ideal for protecting circuits with receivers with high inrush current, minimizing the risk of unnecessary tripping of the circuit breaker.
• Compact dimensions: only 2 modules wide makes it easy to install and saves space in the distribution board.
• Safety and reliability: a product of the renowned manufacturer Eaton, meeting strict safety standards.
• Wide operating temperature range: from -25°C to +75°C allows the circuit breaker to be used in various environmental conditions.
• Versatility: possibility to connect solid and stranded conductors with a cross-section from 1 mm² to 25 mm².
• Energy limitation class: Class 3 provides adequate protection against the effects of electric arc.
• Protection degree IP20: protects against finger contact and the ingress of solid objects larger than 12.5 mm.

The FAZ-B4/2 circuit breaker is a solid and reliable solution for every installer and end-user looking for safe and effective protection of their electrical installation.
