EATON FDC3100 Molded Case Circuit Breaker, Type Fdc, 3-Pole, 100A, 600VAC, 250 Vdc, Load Side, 50/60 Hz

Eaton FDC3100 C Series circuit breaker protects connected receptacles, branch circuits, external motors and HVACs from excess current (overloads) or short circuits. This complete breaker having a completely moulded case has a current rating of 100A and a voltage rating of 600VAC / 250VDC.

Working Mechanism:

• After making sure that this Eaton FDC3100 is the correct circuit breaker for the application, loosely mount the unit on a panel or mounting surface. Also, make sure that the accessory wirings can be reached and the unit can be bolt-on mounted. Install & tighten the breaker mounting using screws, washers & nuts.
• Install an optional terminal end cover if necessary and then connect the line & load terminals with the accessory leads. Install the terminal shield & interphase barrier if needed.
• Finally, check all the mounting & terminal connecting hardware to finish up the installation.
• After switching the circuit breaker On, its contacts pass current through it under normal conditions.
• But when a fault or issue is detected, they 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 before resetting.

Features:

• Eaton FDC3100 circuit breaker has load-side lug terminals for quick installation of circuit wires.
• This 3-pole complete breaker is equipped with fixed thermal & fixed magnetic contacts for long-time and instantaneous tripping performance using its high-speed "blow-open" action.
• It has bolt-on mounting style for easy & secure installation on panels.
• This 50 / 60 Hz breaker unit has an F-frame for housing current-carrying parts, trip devices & mechanisms inside it, offering reverse-feed capability.
• The unit's handle actuator has three positions (ON, OFF and trip) for easy identification of the breaker's status.
