Description
Built for protection against overloads and short circuits, the Siemens E63B100 molded case circuit breaker is rated 100A and 600VAC with 3 poles and 3-phase operation. Its E-Frame measures 6.35 in high and 3.92 in deep. Thermal magnetic tripping provides long-time and instantaneous protection (LI). UL 489 interrupting ratings are 25kA at 480VAC and 18kA at 600VAC. The terminal connection is a load side lug.Specifications

Product FAQs
5 answersHow should I use the 100A rating when selecting the Siemens E63B100?
Use the 100A rated current when coordinating breaker selection with the circuit load and conductor ampacity. The current rating guides overload protection selection, while the interrupting rating must be checked separately.
What system voltage should I check before selecting this breaker?
The Siemens E63B100 is rated 600VAC. Select it for an AC system within that voltage rating, and check the interrupting rating at the system voltage.
How much available fault current can the Siemens E63B100 interrupt?
Its UL 489 interrupting ratings are 25kA at 480VAC and 18kA at 600VAC. Compare available fault current at the installation point with the rating for the system voltage; it must not exceed that interrupting rating.
How does the trip protection work, and can I adjust it?
The thermal-magnetic LI trip provides long-time overload and instantaneous short-circuit protection. The thermal element responds to sustained overloads, and the magnetic element responds to short-circuit currents. Both are fixed, so select the breaker for an application that does not require adjustable trip settings.
How are the load conductors connected?
The load-side connection uses lugs. Plan the outgoing conductor terminations as lug connections, with conductors secured at the load-side terminals.
