Overcurrent circuit breaker series 10kA 3-pole FAZ-Z0,5/3 278918

Three-pole overcurrent circuit breaker – reliable installation protection

This three-pole overcurrent circuit breaker from the FAZ-Z0.5/3 series is a key element ensuring the safety of electrical installations. Designed to protect circuits against overload and short circuit, it performs well in both domestic and industrial applications. The rated switching capacity of 10 kA guarantees an effective response in emergency situations, minimizing the risk of damage and fires.

Characteristics and application

The circuit breaker is characterized by a Z characteristic, which means a delayed response to current increase. This makes it particularly useful in circuits with devices generating high inrush currents during start-up – e.g. motors or transformers. The rated current of 0.5A makes it ideal for protecting delicate circuits with low power consumption. The possibility of mounting on a TH35 rail (not specified in the data, but standard for this type of circuit breaker) facilitates integration with existing switchboards.

Key features and benefits

• High switching capacity: 10 kA at 400V and 230V ensures effective protection even in the event of serious short circuits.
• Z characteristic: Delayed response allows for trouble-free starting of devices with high starting current, avoiding unnecessary circuit tripping.
• Wide voltage range: Suitable for operation at a rated voltage of 400V and an impulse voltage of 4kV.
• Solid construction: Energy limitation class 3 and protection degree IP20 guarantee durability and resistance to environmental conditions.
• Versatility: The possibility of connecting wires with a cross-section from 1 to 25 mm² (solid and stranded) ensures compatibility with various types of installations.
• Safety: Compliance with IEC 60947-2 standard confirms the high level of safety and reliability of the device.
• Operating temperature range: From -25°C to +75°C enables operation in difficult environmental conditions.

The FAZ-Z0.5/3 circuit breaker is an investment in the safety and reliability of your electrical installation – both for professional installers and end users. Its solid construction and advanced technical parameters guarantee long-term and trouble-free operation, protecting against the effects of overloads and short circuits.
