Combined circuit breaker 6kA type A HNB-B25/1N/003-A 195135

Combined circuit breaker – protection and convenience in one device

This 6kA Type A combined circuit breaker is a reliable solution for ensuring safety in electrical installations. It combines the functions of an overcurrent and residual current device, offering comprehensive protection against the effects of short circuits, overloads, and electric shock. The device is designed for both home (xPole Home) and professional applications where high reliability and compactness are required.

Functionality and technical parameters

The circuit breaker is characterized by a rated current of 25A and a residual current sensitivity of Type A (30mA), which provides effective protection against dangerous leakage currents, especially in circuits powering electronic devices. The B tripping characteristic ensures a quick response to sudden current increases, and the short-circuit breaking capacity of 6kA ensures safety in the event of serious failures. The device's construction includes dual screw/busbar terminals, making it easy to connect wires with a cross-section of up to 25mm², providing flexibility during installation.

• Comprehensive protection: Combination of overcurrent and residual current functions in one device.
• Fast response: B characteristic ensures quick disconnection of the circuit in case of overload or short circuit.
• High breaking capacity: 6kA guarantees safety even in the event of serious failures.
• Installation flexibility: Dual screw/busbar terminals allow easy connection of wires of different cross-sections.
• Status indicator: Red-green contact position indicator facilitates quick visual inspection of the device status.
• Voltage independence: Voltage-independent tripping ensures reliable operation even with voltage fluctuations.
• Testing: Required testing every 6 months ensures continuous device efficiency.

Construction and application

The circuit breaker is designed for easy mounting on a TH 35 DIN rail, and its compact dimensions (2 module width) save space in the distribution board. The device operates independently of the mounting position (vertical/horizontal), which further increases its versatility. It is an ideal solution for electrical installations in residential, commercial, and industrial buildings where high reliability and protection against the effects of electrical failures are required. The use of a combined circuit breaker minimizes the risk of electric shock and damage to electrical equipment, ensuring the safety of users and protecting against fire.
