The device is built to withstand rigorous operational conditions, offering long-term reliability and consistent performance in complex electrical networks.
Suitable for
Industrial power distribution boards
Commercial building electrical systems
Protection of electrical motors and heavy machinery
Main power supply isolation in medium-sized facilities
When it may not be suitable
This device is not intended for residential applications where lower current ratings are standard. It is also not suitable for single-phase electrical circuits, as it is specifically designed for 3-pole power distribution systems.
Key specifications
Rated current: 160A
Number of poles: 3
Breaking capacity: 36kA
Application: Industrial and commercial power distribution
How to use
The circuit breaker should be installed by a qualified electrician in accordance with local electrical codes and safety regulations. It is typically mounted on a standard DIN rail or fixed within a distribution enclosure. Ensure that the supply cables are correctly sized for a 160A load and securely fastened to the terminals. After installation, verify the connections and perform a functional test to ensure the breaker operates correctly under load.
What to consider before purchase
Verify that the 160A rating matches your specific load requirements
Ensure the 36kA breaking capacity is sufficient for your installation's short-circuit potential
Confirm that your distribution board has adequate space for a 3-pole modular device
Check compatibility with existing busbar systems or cable lugs
Usage recommendations
Always ensure the power supply is completely disconnected before attempting installation or maintenance. Regularly inspect the terminals for signs of heat or loose connections to maintain optimal performance and safety.
