CUTLER-HAMMER HFD65K HFD3125L 125A 3 POLE INDUSTRIAL CIRCUIT BREAKER

CUTLER-HAMMER（EATON）HFD3125L，HFD65K series，is heavy-duty 3-pole moulded case circuit breaker (MCCB) of Eaton Series C F-frame low voltage power distribution series. The thermal-magnetic fixed trip circuit breaker rated current 125A, rated voltage 600VAC /250VDC, 65kA interrupt capacity at 480V AC, 50/60Hz. This moulded case circuit breaker supports feed-thru terminal connection, can be fitted with optional modular accessories such as auxiliary contact, shunt trip and under voltage release. The moulded case circuit breaker adopts robust molded insulating housing, vibration-resistant construction for industrial and marine low voltage switchboard cabinets.

This breaker delivers low voltage overload & instantaneous short-circuit protection logic control. The low voltage overload & instantaneous short-circuit protection logic control uses thermal bimetallic element for long time overload protection and magnetic trip element for instant short-circuit tripping. The low voltage overload & instantaneous short-circuit protection logic control isolates faulty feeder rapidly to protect busbars, power cables and downstream loads. The low voltage overload & instantaneous short-circuit protection logic control provides NO/NC dry contact feedback signals of breaker ON/OFF and trip status to vessel monitoring & automation system. The low voltage overload & instantaneous short-circuit protection logic control supports built-in trip characteristic stability inspection and hardware self-diagnosis.

This CUTLER-HAMMER spare is an essential low voltage feeder protection spare for industrial and marine switchboard overhaul. The low voltage feeder protection spare can replace faulty HFD3125L breakers directly. The low voltage feeder protection spare meets UL489 safety specifications. The low voltage feeder protection spare is widely fitted on petrochemical plants, cargo ships, tankers and offshore platform low voltage main feeder panels.

CUTLER-HAMMER HFD3125L HFD65K MCCB provides thermal-magnetic protection for LV feeders. It cuts off fault circuit quickly during overload or short-circuit, performing reliably under vibration and humid industrial & marine machinery room environments.
