Description
Part of the legacy F-frame series, this 3-pole, 35A molded case circuit breaker from Siemens delivers robust thermal-magnetic protection for commercial applications. The bolt-on configuration fits older ITE and Siemens E-frame panelboards. For modern cross-references, this discontinued unit is replaced by the ED63B035. With an interrupting capacity of 14 kAIC at 480V, it includes a non-interchangeable trip unit. The breaker is HACR rated and utilizes a trip-free mechanism.Specifications

Product FAQs
6 answersWhich panelboards are compatible with the F3B035 circuit breaker?
This F-Frame breaker features a bolt-on mounting style specifically designed to integrate into legacy ITE and Siemens E-Frame panelboards. It allows you to maintain older infrastructure without requiring modern retrofit kits.
Is the trip unit on this breaker adjustable?
No, the F3B035 is equipped with a fixed thermal-magnetic trip unit providing long-time and instantaneous (LI) protection. Because the trip settings are fixed, no field calibration or adjustment is required during installation.
Does the interrupting capacity change based on the system voltage?
Yes, the short-circuit interrupting rating scales with the operating voltage. It provides a maximum 25kAIC at 240VAC, which decreases to 14kAIC for both 480VAC and 600VAC systems.
Can the F3B035 be used in direct current (DC) applications?
Yes. While primarily used in AC systems up to 600VAC, this breaker is also certified for 250VDC applications with a 10kA interrupting capacity, making it suitable for specific industrial DC control circuits.
What conductor types and sizes are supported by the factory lugs?
The standard lug terminals accommodate wire sizes ranging from 14 AWG up to 1/0 AWG. They are dual-rated for safe termination of both copper (Cu) and aluminum (Al) conductors.
Will the F3B035-R replace an older ITE branded F3B035?
Yes, this unit serves as a direct replacement for legacy ITE F3B035 breakers. It maintains the exact physical dimensions and bolt-on configuration needed to swap out older components seamlessly.
