Eaton FD3090 C Series circuit breaker prevents damage to the circuit due to excess current (overloads) or short circuits in connected receptacles, branch circuits, motors and HVACs / HVARs. This 50 / 60 Hz complete breaker has a current rating of 90A and a voltage rating of 600VAC / 250VDC at a temperature rating of 40 degrees C.
Working Mechanism:
- Mount the unit loosely on a panel or mounting surface while ensuring that the accessory wirings can be reached and the unit can be mounted.
- Install & tighten the mounting using screws, washers & nuts.
- Install an optional terminal end cover if required and then connect the line & load terminals to the accessory leads. Install the terminal shield & interphase barrier if necessary.
- Finally, check all the mounting & terminal connecting hardware to finish up the installation.
- Switch the circuit breaker On to pass current through the contacts.
- When a fault or issue is detected, these contacts move away from each other and trip the unit.
- Users should first troubleshoot the issue before resetting the breaker.
- In case of a thermal trip, the circuit breaker needs to cool down first before resetting.
Features:
- Eaton FD3090 circuit breaker has standard pressure load terminals (load side terminals) for quick installation of 14 to 1/0 AWG circuit wires.
