EATON EHD3025 Molded Case Circuit Breaker, F-Frame, Ehd Type, 3-Pole, 25A, Load Side, 50/60 Hz

Eaton C Series EHD3025 bolt-on circuit breaker is designed for switchboard, panelboard, busway and motor control centre (MCC) applications to interrupt excessive current flow and protect devices from electrical hazards.

Working Mechanism:

• C Series EHD3025 bolt-on 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 EHD3025 circuit breaker comprises a load-side lug for positive connections and a fixed instantaneous thermal-magnetic trip to actuate the breaker opening in the event of a ground fault.
• This three-pole unit allows panel mounting for secure installation.
• It comes in a moulded case to protect the electric circuit from faults.

Standards and Approvals:

• UL
