EATON HFD3100 C Complete Molded Case Circuit Breaker, F-Frame, Hfd, Complete Breaker

Eaton HFD3100 moulded case circuit breaker has an F-frame. It provides overcurrent protection and safe switching in DC & AC systems.

Working Mechanism:

• The circuit breaker is opened when pressure is applied to the trigger.
• When faulty current flows through any part of the system, the trip coil of the breaker gets activated, thus moving away from each other and opening the circuit.

Features:

• It has a non-interchangeable thermal-magnetic trip unit offering both long-time and instantaneous current limiting functions.
• This circuit breaker has a 100A standard current rating with a maximum interrupting capacity of 65kAIC.
• It is equipped with bolt-on load side lug terminals for secure connection.
• This circuit breaker features 3-pole, 3-phase configuration for high'speed blow open action.

Standards and Approvals:

• UL

Frequently Asked Questions:

Q. What is the maximum operating temperature of Eaton HFD3100 moulded case circuit breaker?

A. This circuit breaker can be operated at temperatures up to 40 degrees C.

Q. What is the difference between MCCBs and MCBs?

A.

• MCBs protect items from current overloads while MCCBs protect equipment from fault currents & excess temperature rise.
• The tripping circuit of MCBs is fixed while MCCBs have a movable tripping circuit.
• MCBs have comparatively low interrupting ratings than MCCBs.

Q. What causes moulded case circuit breakers to trip?

A. Overloading of a circuit is the primary reason that leads to frequent short-circuit tripping.
