EATON HFD3050 Molded Case Circuit Breaker, F-Frame, Type Hfd, 3-Pole, 50 A, 600 Vac, 250 Vdc, 50/60 Hz

Eaton HFD3050 circuit breaker is an Eaton C Series circuit breaker ideal for protecting devices from electrical damage caused by excess current or short circuits. Its current-carrying parts, trip device & mechanisms are housed inside a moulded case having F-frame for operating at temperatures ranging from -4 to 158 degrees C.

Working Mechanism:

• Eaton HFD3050 circuit breaker normally passes current through its current-carrying contacts.
• When it detects any faults or issues, the contacts move away from each other and trip the unit thermally or magnetically.
• Troubleshoot the issue. Reset the breaker by moving the breaker handle to the OFF position and then switching the circuit back to On.
• In case of a thermal trip, the circuit breaker needs to cool down before resetting.

Features:

• Eaton HFD3050 circuit breaker accommodates 14 AWG to 1/0 AWG wires inside its load side lug terminals.
• This complete breaker features fixed thermal & magnetic contacts for a superior tripping performance and long-time and instantaneous current limiting protection.
• Its bolt-on mounting style allows easy installation on panels or switchboards.
• This 3-pole circuit breaker operates at a maximum trip setting of 225A & a minimum trip setting of 15A.
• The unit has three indicated positions (ON, OFF and trip) on the sliding handle barrier shown with the international symbols I / 0 and colour-coding strip indicating red for ON, white for tripped and green for OFF.

Compatible Accessories:

• Load Centres, Panels & Switchboards: This Eaton HFD3050 breaker can easily fit onto panelboards, switchboards, motor control centres and busways for smooth operation.

Standards and Approvals:

• CSA
• IEC
• UL

Frequently Asked Questions:

Q. What are the different performance ratings of this Eaton HFD3050 circuit breaker?

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.
