Product FAQs
7 answersWhich panelboards are compatible with the HE2B020 circuit breaker?
This bolt-on breaker is designed for use in Siemens P1, P2, and P3 panelboards, as well as compatible Siemens switchboards.
Is the HE2B020 a direct replacement for older ITE E-frame breakers?
Yes, this Siemens HE-frame breaker replaces legacy ITE HE2B020 models and fits the same bolt-on mounting footprint in existing E-frame panel spaces.
What wire sizes and materials are accepted by the HE2B020 lugs?
The terminal lugs accept 14 to 10 AWG copper wire or 12 to 10 AWG aluminum wire.
Can the HE2B020 be used in DC applications?
Yes, this breaker is rated for up to 250VDC with an interrupting capacity of 30kAIC.
Does this breaker feature adjustable trip settings?
No, the HE2B020 uses a fixed thermal and fixed magnetic trip unit for standard long-time and instantaneous protection.
How does the HE2B020 mount into the panelboard?
It utilizes a bolt-on connection, requiring secure fastening to the panelboard bus bars rather than snapping into place. Ensure the panel is de-energized before bolting the breaker to the bus.
How does the interrupting capacity of the HE2B020 scale with system voltage?
The short circuit rating decreases as system voltage increases. It provides 65kAIC at 240VAC, 25kAIC at 480VAC, and 18kAIC at 600VAC.
