Description
Designed for industrial applications, the Siemens HFD63B225L is a 3-pole, 225A molded case circuit breaker from the Sentron series. It delivers robust long-time and instantaneous (LI) protection. This unit-mount MCCB is engineered for standalone enclosures and switchboards. The "L" suffix indicates it comes factory-equipped with line and load lugs for immediate wire termination. Featuring a 65kAIC rating at 480VAC, it utilizes a non-interchangeable trip unit for tamper-resistant performance.Specifications

Product FAQs
6 answersWhat is the difference between the Siemens FD63B225L and the HFD63B225L?
The "H" in the HFD63B225L catalog number designates a high interrupting rating. The HFD63B225L provides a 65kAIC rating at 480VAC, while the standard FD63B225L is rated for 35kAIC at 480VAC.
What is the magnetic trip adjustment range for the HFD63B225L?
The HFD63B225L features an adjustable magnetic trip range from 1100A to 2500A. This allows you to fine-tune the instantaneous short-circuit protection for your specific application.
What does the "L" suffix in the HFD63B225L catalog number indicate?
The "L" suffix signifies that the breaker comes factory-equipped with line and load side lugs. Specifically, it includes TA1FD350A lugs, which accept 6 AWG to 350 kcmil copper or 4 AWG to 350 kcmil aluminum wire.
Is the HFD63B225L a plug-in or bolt-on breaker?
The HFD63B225L is a unit-mount (feed-thru) breaker. It is designed to be hard-mounted in Siemens Sentron panelboards, switchboards, or standalone enclosures, rather than plugging directly into a busbar.
What type of trip unit is installed in the HFD63B225L?
This breaker utilizes a thermal-magnetic trip unit. It provides fixed thermal protection for long-time overloads and adjustable magnetic protection for instantaneous short circuits.
Can the HFD63B225L be used in DC applications?
Yes, the HFD63B225L is rated for use in DC systems up to 500VDC, where it provides an interrupting capacity of 25kA.
