When it may not be suitable

This device is not intended for residential applications where lower current ratings are typically required. It is also not suitable for DC electrical systems, as it is specifically designed for AC power distribution.

Key specifications

• Number of poles: 1
• Rated current: 100A
• Tripping curve: B
• Breaking capacity: 10kA
• Technology: Thermal-magnetic

How to use

The device is designed for DIN rail mounting within a standard electrical distribution board. Installation should be performed by a qualified electrician in accordance with local electrical regulations. Ensure that the supply cables are correctly sized for a 100A load and securely tightened to the terminals to prevent overheating. Once installed, the toggle switch allows for manual operation to disconnect or reconnect the circuit as needed.

What to consider before purchase

• Verify that the 100A rating matches your circuit requirements
• Ensure the B-curve characteristic is appropriate for your specific load type
• Check that your distribution board has sufficient space for a 1-pole module
• Confirm compatibility with AC power systems

Usage recommendations

Regularly inspect the terminal connections for tightness and ensure the device is free from dust or debris to maintain optimal performance and safety.
