Description

A robust solution for commercial power systems, this 90A molded case breaker provides reliable long-time and instantaneous trip functions. The 3-pole HEB frame device is engineered to handle high fault currents in demanding environments. It fastens into Siemens P1, P2, and P3 panelboards via a bolt-on connection. For future upgrades, this unit is replaced by the 3VA4190-6ED34-0AA0, which requires a 3VA41 strap kit. The breaker is HACR rated and delivers 65kAIC at 480VAC.

Product FAQs

5 answers
Which Siemens panelboards are compatible with the HEB3B090B circuit breaker?

This bolt-on breaker is designed for use in Siemens P1, P2, and P3 panelboards. It mounts directly to the panel bus using a bolted connection for secure power distribution.

Is the HEB3B090B rated for direct current (DC) applications?

Yes, this breaker is rated for DC systems up to 125/250VDC, providing a 42kA interrupting capacity for these specific applications.

What type of wire can be used with the factory lugs on this breaker?

The standard lugs accept both copper (Cu) and aluminum (Al) conductors ranging from 14 AWG to 1/0 AWG. Ensure proper torque specifications are followed during installation.

How does the HEB frame differ from the standard NEB frame?

The HEB frame offers a higher interrupting capacity (65kAIC at 480VAC) compared to the standard NEB frame (35kAIC at 480VAC). Both share the same physical dimensions and mount in the same panelboard spaces.

Does this breaker have adjustable trip settings?

No, the HEB3B090B features a fixed thermal-magnetic trip unit with preset long-time and instantaneous (LI) trip functions. It cannot be adjusted in the field.
