What is the Hager HDA160U circuit breaker used for?
The Hager HDA160U is a miniature circuit breaker designed to protect electrical circuits against overloads and short circuits. It is commonly used in residential and commercial distribution panels.
How many poles does the HDA160U have?
The HDA160U is a 1-pole circuit breaker. It switches and protects only one live conductor.
How do I know if the HDA160U has tripped?
When the circuit breaker trips, the switch handle moves to a middle position between ON and OFF. To reset, push the handle to OFF, then back to ON. Always identify and correct the cause of the trip first.
Can I install the HDA160U myself?
Installation should only be performed by a qualified electrician. Disconnect the power supply before working on the panel to avoid electric shock.
What does the 'C' tripping curve mean?
The C curve indicates the breaker trips at 5 to 10 times its rated current (In). It is suitable for general loads like lighting and socket circuits, where brief inrush currents are moderate.
How should I clean and maintain the circuit breaker?
Keep the breaker clean and dry. Wipe the exterior with a soft, dry cloth. Do not use solvents, water, or abrasive cleaners. Periodically check that the terminal connections are tight and that there are no signs of overheating.
What wire sizes can be connected to the HDA160U?
The terminals accept conductors from 1 to 25 mm². Both rigid and flexible cables can be used, and it is recommended to use ferrules for flexible strands.
Does the HDA160U provide protection against earth leakage?
No, it is a circuit breaker only. It does not detect earth leakage currents. For protection against electric shock, install a separate Residual Current Device (RCD) in series.
What are the standard dimensions for the HDA160U?
The HDA160U is a modular device with a width of 18 mm (1 module) and a height/ depth compatible with standard DIN rail enclosures. Its compact size ensures easy installation in distribution boards.
