Boost electrical safety in your setup with this MCB from ABB. When it detects a short-circuit or current overload, the unit quickly steps in, cutting the power supply to protect downstream components in the system. Type-D tripping characteristics mean the breaker trips when the current exceeds 10 to 14 times its 4A rating, making it suitable for use with heavy-duty machinery. A built-in contact position indicator shows its operating status for easy troubleshooting and status-checking.

• Low power loss of 1.7W for energy-efficient operation
• Rated impulse withstand voltage of 4kV offers a high level of electrical safety
• Front-facing toggle switch for quick resetting after a trip
• Integrated actuator marking for convenient operation
• Built-in resistance to shock and vibration for durability in demanding conditions

• Construction sites
• Agricultural machinery
• Manufacturing facilities
• Data centres

You mount this MCB by simply clipping it onto a DIN rail, so no tools are necessary.

It has a high breaking capacity of 6kA, making it suitable for protecting high-power electrical systems.
