• Implemented in commercial buildings for power management

What happens if the operational current exceeds the rated limit?

Exceeding the operational current of 250A may trigger the built-in thermal protection, leading to the circuit breaker tripping to prevent overheating and potential damage to connected equipment.

How does the adjustable overload protection work?

The adjustable overload protection allows users to set the desired threshold between 175A and 250A based on specific load requirements, ensuring optimal performance while safeguarding against current surges.

Can this device function in extreme temperatures?

Yes, it operates efficiently between -25°C and 70°C, allowing flexible deployment in various environments, including harsh industrial settings.

What is the advantage of the Type S tripping characteristics?

Type S tripping characteristics provide precise fault detection, reducing the risk of nuisance tripping and allowing for more accurate operation in complex circuit configurations.

How does the breaking capacity vary with different voltage levels?

The breaking capacity is maximised at 36 kA for 415V, ensuring safe interruption of high fault currents, while it decreases for higher voltages, notably lower for 690V at 7 kA, tailored to specific application needs.
