EATON ED3225 Molded Case Circuit Breakermolded Case Circuit Breaker, 225 A

Eaton C Series ED3225 bolt-on circuit breaker is ideal for switchboard, panelboard, busway and motor control centre (MCC) applications. It is used for protecting electric circuits from damage.

Working Mechanism:

• This C Series ED3225 circuit breaker is controlled by the circuit breaker handle and Push-to-Trip button.
• The unit passes current through its current-carrying contacts.
• When a fault is detected, the contacts back off from each other, tripping the unit thermally or magnetically.
• Reset the breaker by moving the breaker handle to the OFF position.
• Finally, switch the circuit back to the ON position.

Features:

• Eaton C Series ED3225 circuit breaker comes with an ABC phase connection to protect devices from overloads or short circuits.
• It comprises a load-side lug for secure connections and allows a toggle-handle actuation method to control the flow of electric current.
• The inside contents (including mechanisms, current-carrying parts & trip devices) are contained in a moulded case to protect the electric circuit from foreign particles.
• This unit comes with a fixed thermal-magnetic trip to actuate the breaker opening in the event of a ground fault.
• This 3-pole unit allows bolt-on panel mounting for secure installation.

Standards and Approvals:

• UL
• CSA
• IEC
