Description
Maintaining older electrical systems is simplified with the Siemens FJ62B225, a 225A thermal-magnetic breaker. This 2-pole component is engineered for commercial environments requiring dependable F-frame hardware. It fits perfectly into classic ITE F-Frame panelboards and Siemens P1, P2, and P3 configurations. Engineers rely on this exact form factor to avoid panel modifications. With a 22kA rating at 480VAC, it features an adjustable magnetic trip for tailored short-circuit response.Specifications

Product FAQs
4 answersWhich panelboards are compatible with the FJ62B225 circuit breaker?
This bolt-on breaker is designed for use in legacy ITE F-Frame panelboards, as well as Siemens P1, P2, and P3 panelboards. It maintains the exact F-frame form factor to avoid panel modifications during retrofits.
What wire sizes and materials are accepted by the standard lugs on the FJ62B225?
The standard lugs accept wire sizes ranging from 6 AWG up to 350 kcmil. They are rated for both copper and aluminum conductors.
How does the adjustable magnetic trip function operate on this breaker?
The adjustable magnetic trip allows electricians to modify the instantaneous short-circuit response threshold to coordinate with downstream devices or specific load inrush characteristics. The thermal overload setting remains fixed at 225 amps.
What are the modern equivalents to the legacy FJ62B225 breaker?
The FJ62B225 is a legacy F-frame breaker. Modern replacements typically include the Siemens Sentron FD62B225 or FXD62B225. However, upgrading to a Sentron series breaker in an older ITE panelboard may require specific adapter hardware.
