Differences Between HFD3150L and FD3150L
Both the HFD3150L and FD3150L are molded case circuit breakers of Eaton Series C F-Frame. They are complete 3-pole 150A units equipped with thermal-magnetic trip units, sharing identical overall dimensions and mounting hole positions. Their main differences lie in interrupting rating, applicable working conditions and cost, as detailed below:
Different Short-Circuit Interrupting Capacity (Core Difference)
●HFD3150L: High interrupting type. Its rated interrupting capacity reaches 100kA at 240V AC and 65kA at 480V AC, delivering superior resistance to heavy short-circuit current surges.
●FD3150L: Standard interrupting type. It offers a rated interrupting capacity of 65kA at 240V AC and 35kA at 480V AC, sufficient for protection in ordinary power distribution applications.
Material, Appearance & Design Features
Improve efficiency
● Material:The casing is made of robust material with reliable insulation performance. It withstands high temperatures and physical impacts, resisting aging and cracking even in complex industrial environments. It runs consistently and stably in all types of heavy-duty workshop sites, boasting outstanding durability.
● Appearance:It adopts industry-standard dimensions and fits all common distribution cabinets without taking up extra internal space. The whole unit has a smooth surface with fine workmanship free of burrs, featuring a sturdy and solid look. It delivers a neat, professional appearance whether assembled in domestic complete electrical cabinets or matched with exported machinery and equipment.
● Design:It features an integrated all-in-one design, pre-fitted with thermal-magnetic trip units and line/load terminals at the factory. No extra spare parts need to be purchased separately, and you can wire and install it right after receipt.

FAQ
Q1: Is the HFD3150L a complete circuit breaker or just a bare frame?
A1: The Eaton HFD3150L is a fully assembled complete circuit breaker. It comes with a factory-built fixed thermal-magnetic trip unit and standard line & load terminals. It can be wired and installed directly after purchase with no additional trip components to buy separately.
Q2: What is the interrupting rating of the HFD3150L? Does it vary under different voltages?
A2: Its short-circuit interrupting capacity differs based on operating voltage: 100kAIC at 240VAC, 65kAIC at 480VAC, 25kAIC at 600VAC, and 22kAIC at 250VDC. Please match it according to your actual system voltage and expected short-circuit current during model selection.
Q3: Can the trip current of the HFD3150L be adjusted?
A3: The HFD3150L is equipped with a fixed thermal-magnetic trip. Its trip current value is preset at the factory and cannot be adjusted on site. If you need a model with adjustable trip parameters, you may inquire about Eaton's same-series circuit breakers with electronic trip units.
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.
