Built for industrial environments, this 80A molded case breaker delivers extra-high interrupting capacity and reliable thermal-magnetic trip functions. The bolt-on configuration integrates seamlessly into Siemens Sentron panelboards, switchboards, and motor control centers. Featuring a 65kAIC rating at 480VAC, the HACR-rated ED-frame device includes load-side lugs. For future upgrades, this model crosses over to the 3VA5180-6ED31-0AA0 when paired with the appropriate retrofit hardware.

Product FAQs
6 answers
Which panelboards are compatible with the Siemens HHED63B080?
This ED-frame breaker is designed for installation in Siemens Sentron panelboards, switchboards, and motor control centers that accept bolt-on branch devices.
How does the HHED63B080 connect to the panelboard?
As a bolt-on breaker, it mounts directly to the panelboard bus on the line side using bolted connections. The load side is equipped with mechanical lugs that accept 10 AWG to 1/0 AWG copper or aluminum conductors.
What does the HHED6 series designation indicate?
The HHED6 series signifies that this is an ED-frame breaker with an extra-high interrupting capacity. It is engineered to safely clear severe fault currents, providing up to 100kAIC at 240V AC and 65kAIC at 480V AC.
What is the modern replacement for the HHED63B080?
For future upgrades or panel retrofits, the HHED63B080 crosses over to the Siemens 3VA5180-6ED31-0AA0 molded case circuit breaker, provided the appropriate retrofit mounting hardware is used.
How does the trip unit on the HHED63B080 operate?
The breaker utilizes a fixed thermal-magnetic trip unit. The thermal component provides long-time (L) protection against continuous overloads, while the magnetic component delivers instantaneous (I) protection to quickly clear short circuits.
Is the HHED63B080 suitable for direct current (DC) applications?
Yes, in addition to standard AC systems, this breaker is rated for use in DC electrical networks up to 250V DC, providing a maximum interrupting capacity of 30kA.
