A. Eaton HFD3050 breaker has a current rating of 50A and a voltage rating of 600VAC / 250VDC. This circuit breaker has an interrupt rating of 100kA at 240VAC, 65kA at 480VAC, 25kA at 600VAC and 22kA at 250VDC.

Q. How to install this circuit breaker?

A.

• First, make sure that this Eaton HFD3050 is the appropriate circuit breaker for the application.
• Use a bolt drilling plan, ensuring that the mounting panel is predrilled. Only the load-end support mounting holes are needed for panelboard mounting. Make sure the panel cover is cut out to correct the escutcheon dimension in dead front cover applications.
• Mount the unit on the panel or mounting surface while making sure that the accessory wirings can be reached. Install & tighten the mounting screws, washers & nuts.
• Install an optional terminal end cover if required. Connect the line & load terminals and accessory leads. Install the terminal shield & interphase barrier if needed.
• Finally, check all the mounting & terminal connecting hardware.

Q. What are points to inspect before operating this Eaton HFD3050 circuit breaker?

A.

• Remove the dust, dirt, grease or moisture from the unit.
• Check that the mechanical linkages are free by switching the unit ON & OFF several times.
• Press the push-to-trip button at the bottom side of the unit to mechanically trip & test the proper functioning of the circuit breaker.
• Inspect the unit of any cracks, chipping or discolouration. Tighten the terminals & connectors. Check the mounting hardware.
• Remove any safety hazards near the installed area.
