What is Eaton HFD3100L Circuit Breaker?
Our Eaton HFD3100L is a high-interrupt F-frame molded case circuit breaker built on Eaton's Series C platform, with a rated current of 100A for 3 poles and a factory-standard fixed thermal-magnetic trip unit. Designed for operating conditions with high short-circuit currents, it is commonly installed inside industrial distribution cabinets and integrated control cabinets to maintain stable operation of power circuits. It fits a wide range of applications including automated production lines, heavy-duty motor controls, pump station units and large commercial building power distribution projects, and is a popular mainstream model for 100A-rated applications requiring high short-circuit interrupting capacity.
Why Choose Eaton HFD3100L Circuit Breaker?
As an overload protection breaker, the Eaton HFD3100L delivers excellent short circuit protection. It trips and cuts off power instantly when overloads or short circuits occur on the circuit, preventing equipment burnout and production downtime. It serves as an industrial electrical safety breaker that improves power safety in factories.

How to Choose Eaton HFD3100L
Improve efficiency
● Distinguish load types
Motors and standard control cabinets have different load conditions. Motors generate large inrush current during startup, so you need to select based on your actual equipment working conditions.
● Check rated current
This model is rated 100A. Calculate the long-term operating current of your circuit. Mismatched current will lead to frequent tripping or loss of protection functions.
● Confirm interrupting capacity
Cross-check with your factory power distribution parameters. The on-site short-circuit current must not exceed the product standard, otherwise the breaker cannot cut off power safely during faults.

FAQ
Q1: Where is the Eaton HFD3100L mainly applied?
A1: This 3-pole, 100A high-interrupt molded case circuit breaker is mainly used in industrial power distribution with high short-circuit current, motor control centers, heavy-duty equipment circuits, and critical power distribution circuits of commercial buildings. It provides overload and short-circuit protection for environments with high fault current risks.
Q2: What is the interrupting rating of the HFD3100L?
A2: Its rated interrupting capacity reaches 100 kAIC under a 240VAC system and 65 kAIC under a 480VAC system. It features a high interrupting rating among models of the same current rating, suitable for distribution environments with large-capacity transformers and high short-circuit hazards.
Q3: Can this circuit breaker be used for motor protection?
A3: Yes. Its thermal-magnetic trip characteristics accommodate motor inrush starting current, and it can be directly applied to overload and short-circuit protection for motor circuits within 100A. When matched with Eaton motor control components as a complete set, full UL508 SCCR certification can be obtained.
Q4: How can I place an order or apply for bulk purchase discounts?
A4: Send your required order quantity via email to Irene8866@163.com, or leave us a message on WhatsApp (+86 18950163907). We will reply within 24 hours with formal quotation and stock confirmation.
