Suitable for

• Residential electrical distribution boards
• Commercial office lighting circuits
• Protection of low-power electronic devices
• General-purpose branch circuit protection

This device may not be suitable for high-inrush current applications, such as large motor starting or heavy industrial machinery, where a C or D characteristic breaker would be required. It is also not intended for use in environments exceeding its specified voltage or current ratings.

Key specifications

• Number of poles: 2
• Rated current: 4A
• Breaking capacity: 6kA
• Tripping characteristic: B
• Mounting type: DIN rail

Installation should be performed by a qualified electrician in accordance with local electrical codes. The device is designed to be snapped onto a standard DIN rail within an enclosure. Ensure that the supply voltage matches the device specifications and that all terminal connections are tightened to the manufacturer's recommended torque settings to prevent overheating.

What to consider before purchase

• Verify that the 4A current rating is appropriate for your specific load requirements
• Ensure the 6kA breaking capacity meets the short-circuit current levels of your installation
• Check available space in your distribution board for a 2-pole module
• Confirm compatibility with existing DIN rail mounting systems

For optimal performance and safety, regularly inspect the circuit breaker for signs of physical damage or discoloration. Test the device periodically if required by local regulations to ensure the mechanical tripping mechanism remains functional.
