## Summary description

The Hager MCS340 is a high-quality 3-pole miniature circuit breaker designed for reliable electrical circuit protection. Featuring a Type C tripping characteristic and a 40A rated current, this device is suitable for industrial and residential applications. It occupies 3 modules and utilizes QuickConnect technology for efficient installation, ensuring safety and performance in electrical distribution systems.

## Long description

The Hager MCS340 is a professional-grade 3-pole miniature circuit breaker engineered to provide robust protection for electrical circuits in both residential and industrial environments. This device is designed to interrupt current flow in the event of an overload or short circuit, effectively safeguarding connected equipment and wiring. With its Type C tripping characteristic and a 40A rated current, it offers a reliable solution for managing electrical loads that may have moderate inrush currents.
Advantages
The primary benefit of the Hager MCS340 is its integration of QuickConnect technology, which significantly reduces installation time and ensures a secure, vibration-resistant connection without the need for traditional screw terminals. The 3-pole configuration allows for the simultaneous disconnection of three phases, providing comprehensive safety for three-phase electrical systems. Its compact design, occupying only 3 modules on a standard DIN rail, maximizes space efficiency within distribution boards while maintaining high operational reliability and durability.
Suitable for
Protection of three-phase electrical circuits
Industrial machinery and motor control centers
Residential distribution boards for high-load appliances
Commercial electrical installations requiring reliable short-circuit protection
This circuit breaker may not be suitable for applications requiring a different tripping curve, such as Type B for sensitive electronic equipment or Type D for high-inductive loads with significant starting currents. Additionally, it is not intended for use in environments exceeding its specified temperature or humidity ratings, and it should not be installed in circuits where the prospective short-circuit current exceeds the device's rated breaking capacity.
Key specifications
Number of poles: 3
Tripping characteristic: Type C
Rated current: 40A
Mounting type: DIN rail
Width: 3 modules
Connection technology: QuickConnect
To install the Hager MCS340, ensure the main power supply is disconnected. Mount the device onto a standard 35mm DIN rail within the distribution board. Utilize the QuickConnect terminals to insert the stripped conductors firmly into the designated ports until they are locked in place. Verify that all connections are secure and that the wiring corresponds to the electrical diagram of the system before restoring power.
What to consider before purchase
Verify that the 40A rating matches the load requirements of your specific circuit
Ensure the Type C characteristic is appropriate for the connected equipment
Check available space in the distribution board for a 3-module wide device
Confirm compatibility with existing DIN rail mounting systems
For optimal performance and safety, ensure that all electrical installations are performed by a qualified professional in accordance with local electrical regulations. Regularly inspect the circuit breaker for signs of wear or damage and test the functionality periodically to maintain system integrity.
