## Long description

The Legrand TX3 403417 is a high-quality 4-pole miniature circuit breaker engineered to provide robust electrical protection for various installations. This device is designed to monitor and safeguard electrical circuits by automatically disconnecting the power supply in the event of an overload or short circuit, thereby preventing potential damage to wiring and connected equipment. It is built to operate efficiently within a voltage range of 240 to 415 V and supports standard power frequencies of 50 to 60 Hz, making it a versatile component for modern electrical distribution systems.
Advantages
The primary benefit of this circuit breaker is its reliable performance in maintaining electrical safety across residential and industrial environments. Its Type B tripping characteristic ensures a rapid response to fault conditions, providing an optimal balance between sensitivity and operational stability. The 4-pole configuration allows for the simultaneous protection of three-phase systems with a neutral wire, simplifying the installation process and ensuring comprehensive coverage for complex circuits. The compact design and standardized dimensions facilitate easy integration into existing distribution boards and consumer units.
Suitable for
Residential electrical distribution boards
Industrial power supply systems
Protection of lighting and heating circuits
Three-phase electrical installations with neutral
When it may not be suitable
This circuit breaker is not intended for use in environments exposed to moisture, dust, or extreme weather conditions, as it carries an IP20 rating which offers no protection against water ingress. It is also not suitable for circuits requiring a different tripping curve, such as Type C or D, which are typically used for high-inrush current loads like large motors or transformers.
Key specifications
Rated current: 16 A
Number of poles: 4
Tripping characteristic: Type B
Operating voltage: 240 - 415 V
Frequency: 50 - 60 Hz
Protection rating: IP20
Dimensions: 88 mm (height) x 70.8 mm (width) x 77.8 mm (depth)
How to use
The device should be installed by a qualified electrician onto a standard DIN rail within a distribution enclosure. Ensure that the power supply is completely disconnected before beginning the installation. Connect the incoming supply lines to the top terminals and the outgoing load lines to the bottom terminals, ensuring all connections are tightened to the manufacturer's specified torque to prevent overheating. Once installed, the breaker can be toggled manually using the front-facing switch to control the circuit.
What to consider before purchase
Verify that the 16 A rated current matches the requirements of your specific circuit load.
Ensure the 4-pole configuration is compatible with your electrical system wiring.
Confirm that the installation environment is dry and protected from environmental hazards.
Check that the available space in your distribution board accommodates the 70.8 mm width of the device.
Usage recommendations: Regularly inspect the circuit breaker for any signs of physical damage or discoloration. It is recommended to perform a functional test periodically to ensure the tripping mechanism remains responsive and effective.
