Product FAQs
5 answersWhich panelboards are compatible with the Siemens EH3B070?
This 3-pole legacy E-frame breaker is specifically designed for bolt-on installation in Siemens P2 and P3 panelboards, as well as older ITE panelboard systems.
Is there a modern cross-reference replacement for the legacy EH3B070?
Yes, the Siemens ED43B070 is the direct modern equivalent. It fits the exact same physical footprint for seamless integration into P2 and P3 panelboards, while offering an upgraded 18kA interrupting capacity at 480VAC.
What conductor types and sizes do the load lugs support?
The factory lugs are rated for dual-rated copper or aluminum conductors ranging from 10 AWG to 1/0 AWG. When wiring, always ensure conductors are tightened to the precise torque specifications printed directly on the breaker faceplate.
What protection does the LI trip function code provide?
The LI designation indicates that this thermal-magnetic breaker provides fixed Long-Time and fixed Instantaneous protection. The thermal element responds to gradual overcurrent conditions, while the magnetic element clears short-circuit faults immediately.
Can the trip settings on the EH3B070 be adjusted in the field?
No, this specific model features a non-interchangeable trip unit with fixed thermal and fixed magnetic elements. It does not support field adjustments to alter the trip curve thresholds.
