## Long description

The Hager HTN340C is a high-performance 3-pole selective miniature circuit breaker (SLS) engineered to provide reliable protection for electrical distribution systems. Designed for demanding environments, this device ensures precise selective tripping, which helps maintain power continuity in downstream circuits by isolating faults effectively. With a robust construction and a rated current of 40A, it is an essential component for maintaining safety and efficiency in modern electrical installations.
Advantages
This selective miniature circuit breaker offers superior operational reliability by allowing for selective coordination within electrical networks. Its 3-pole configuration makes it highly versatile for three-phase power systems, ensuring that only the faulty circuit is disconnected while the rest of the system remains operational. The device is built to withstand rigorous industrial and commercial conditions, providing long-term durability and consistent performance under varying electrical loads.
Suitable for
Industrial electrical distribution boards
Commercial building power management systems
Three-phase electrical installations requiring selective protection
Main circuit protection in sub-distribution panels
When it may not be suitable
This device is not intended for use in single-phase residential circuits where a standard miniature circuit breaker would suffice. It is also not suitable for applications exceeding its rated current of 40A or for environments that require specific protection characteristics not provided by a selective circuit breaker.
Key specifications
Number of poles: 3
Rated current: 40A
Operating voltage: 230-400V AC
Device type: Selective miniature circuit breaker (SLS)
How to use
The Hager HTN340C is designed for professional installation on a standard DIN rail within an electrical distribution board. It should be installed by a qualified electrician in accordance with local electrical regulations. Once mounted, the input and output cables must be securely connected to the respective terminals, ensuring that all connections are tightened to the manufacturer's specified torque to prevent overheating and ensure optimal electrical contact.
What to consider before purchase
Verify that the 40A rating matches your circuit requirements
Ensure compatibility with your existing 3-phase distribution board layout
Confirm that selective tripping is required for your specific electrical design
Check that the installation environment meets the technical specifications for voltage and load
Usage recommendations
For optimal safety and performance, always ensure that the circuit breaker is installed in a clean, dry environment and is protected from dust and moisture. Regular inspection of the terminal connections is recommended to maintain system integrity over time.
