Product FAQs

5 answers
What is the direct replacement for the legacy ITE F3B020 circuit breaker?

The Siemens ET4032 is the exact drop-in replacement for the legacy F3B020 model. It provides the same 20-amp, 3-pole configuration and mounts directly into older ITE and Siemens F-Frame panelboards without requiring panel modifications.

Which panelboards are compatible with the ET4032 circuit breaker?

This breaker is designed specifically for use with legacy ITE and Siemens F-Frame panelboards. It functions as a direct drop-in solution for older systems requiring an F-Frame unit mount breaker.

What wire sizes and materials are accepted by the lugs on this breaker?

The factory-installed lugs accept 14 AWG to 10 AWG wire sizes. The terminals are rated for use with both copper (Cu) and aluminum (Al) conductors, making it versatile for various field wiring conditions.

Does the ET4032 meet standard commercial interrupting requirements?

Yes, this standard interrupting breaker meets NEMA AB-1 specifications. It provides up to 25kA of fault protection at 240VAC, and 14kA at 480VAC and 600VAC, making it suitable for stable power distribution across commercial networks.

What type of trip mechanism does the ET4032 use?

It features a thermal-magnetic trip unit with fixed thermal and fixed magnetic settings. This provides both long-time overload protection and instantaneous short-circuit protection (LI function) to ensure stable power distribution.
