FAQs

 

What is the main purpose of the DZ158LE Circuit-Break Incorporating Residual Current Protection?

It protects circuits and personnel by combining overload, short-circuit, and residual current protection in a single device, ensuring both electrical and fire safety.

 

Where is this product typically used?

The DZ158LE is suitable for low-voltage distribution systems in residential, commercial, and industrial environments, where both circuit protection and leakage safety are required.

 

What is the breaking capacity of this device?

It provides a 6kA short-circuit breaking capacity, ensuring reliable interruption even under high fault conditions.

 

What does the residual current rating (IΔn) indicate?

The residual current setting (30mA, 100mA, 300mA) determines sensitivity to earth leakage faults. For example, 30mA provides enhanced personal protection, while 300mA offers fire prevention for large installations.

 

How is the DZ158LE installed and maintained?

It is mounted easily on a DIN 35mm rail using a clip mechanism. Maintenance involves regular testing of the residual current function and ensuring terminals are tightened to the specified 3.5 N·m torque.
