Protect your low-voltage electrical circuits from overcurrent with this MCB from ABB. By combining a delayed thermal tripping mechanism with an electromechanical system, this unit offers both short circuit and overload shielding. It cuts the power supply to the circuit when a fault occurs, preventing damage to your components for improved safety. Thermoplastic housing provides reliable impact resistance, making the device suitable for use in harsh environments. Thanks to terminals located out of reach of your fingers, you can operate this MCB safely without risk of contact with live parts.

• Screw termination method is simple and doesn't need complex tools
• Current rating of 4A for energy efficiency and low heat dissipation
• Type C tripping characteristics for a quick response to current spikes
• Mechanical service life of 20,000 operating cycles for long-term performance

• Domestic consumer units
• Switchgears
• Industrial lighting systems

The device is designed for clip-on mounting on DIN rails. This process is simple and doesn't need any tools, saving time and effort.

This MCB has an IP40 rating, meaning it can withstand tools and objects larger than 1mm in size.
