Description
A reliable choice for commercial facilities, the Siemens HEB3B040B is a 3-pole, 40A molded case circuit breaker. It utilizes fixed thermal and magnetic trip elements to safeguard critical electrical infrastructure. This bolt-on MCCB is engineered for Siemens P1, P2, and P3 panelboards. While this specific HEB frame is replaced by the 3VA4140-6ED34-0AA0 (which requires a 3VA41 strap kit), this unit maintains the original footprint. It offers a 65kAIC rating at 480V and is HACR and HID rated.Specifications

Product FAQs
5 answersWhich Siemens panelboards are compatible with the HEB3B040B circuit breaker?
This bolt-on breaker is designed for use in Siemens P1, P2, and P3 series panelboards. It connects directly to the panelboard bus.
What wire sizes are accepted by the terminals on the HEB3B040B?
The factory-installed load side lugs accept wire gauges from 14 AWG up to 1/0 AWG. The terminals are rated for both copper (Cu) and aluminum (Al) conductors.
Can the HEB3B040B be used in DC voltage systems?
Yes, this thermal-magnetic breaker is rated for DC applications up to 125/250VDC, providing an interrupting capacity of 42kAIC at those voltages.
How does the HEB frame compare to the NEB frame in the Sentron series?
Both share the same physical footprint for P1, P2, and P3 panelboards, but the HEB frame offers a higher interrupting rating (65kAIC at 480VAC) compared to the standard NEB frame (35kAIC at 480VAC).
Does the HEB3B040B require a separate mounting kit?
As a bolt-on breaker, it mounts directly to the bus of compatible Siemens P1, P2, and P3 panelboards without requiring a separate plug-in mounting base.
