Description
Engineered for commercial and industrial applications, the Siemens HE2B100 operates as a 100-amp, two-pole molded case circuit breaker. It provides a seamless solution for maintaining older electrical infrastructure. Designed for bolt-on mounting, it fits perfectly into legacy Siemens P1, P2, and P3 switchboards. This model serves as the predecessor to the HED42B100, offering the same footprint for easy swap-outs. Rated for 65kA at 240VAC, it utilizes fixed thermal-magnetic trip functions.Specifications

Product FAQs
7 answersWhat panelboards are compatible with the HE2B100 breaker?
This E-frame breaker is designed for bolt-on installation in Siemens P1, P2, and P3 panelboards, as well as compatible Siemens switchboards.
What wire size and material does the HE2B100 accept?
The standard lugs on this breaker accept 10 AWG to 1/0 AWG wire. Both copper (Cu) and aluminum (Al) conductors are supported.
Can the HE2B100 be used in direct current (DC) systems?
Yes, this thermal magnetic breaker is rated for DC applications up to 250VDC, providing a 30kA interrupting capacity at that voltage.
Are the trip settings adjustable on this breaker?
No, the HE2B100 features a fixed thermal and fixed magnetic trip unit. It provides standard long-time and instantaneous (LI) protection without adjustable dials.
How does the HE2B100 connect to the panel bus?
It utilizes a bolt-on connection type, requiring it to be physically bolted to the panelboard busbars rather than snapping into place.
How does the interrupting capacity change based on system voltage?
The maximum interrupting rating is 65kA at 240VAC. The rating decreases at higher voltages, offering 25kA at 480VAC and 18kA at 600VAC.
Is the HE2B100 interchangeable between ITE and Siemens branding?
Yes, Siemens acquired ITE. Breakers with the HE2B100 catalog number may carry either the ITE or Siemens brand name while maintaining the exact same physical and electrical characteristics.
