Description
Built for industrial switchboards and motor control centers, this 30-amp unit-mount breaker features factory-installed line and load lugs for standalone enclosure applications. The thermal-magnetic trip unit delivers precise long-time and instantaneous protection for critical commercial infrastructure. Capable of handling 42kA fault currents at 480VAC, it includes HACR and HID ratings for versatile deployment. This specific model is superseded by the 3VA5130-6EC36-0AA0 for newer installations.Specifications

Product FAQs
5 answersWhat does the L suffix in the HED43B030L catalog number mean?
The L suffix indicates that the circuit breaker is shipped factory-assembled with both line and load side lugs included. Without this suffix, the frame, trip unit, and lugs would typically be ordered or packaged separately.
How does the HED43B030L differ from a standard ED43B030L breaker?
The H in the HED4 prefix designates it as a high-interrupting capacity breaker. It safely clears higher fault currents (up to 42kA at 480VAC) compared to standard ED4 models, making it suitable for systems with higher available short-circuit current.
Can the Siemens HED43B030L be reverse fed?
Yes. Siemens Sentron ED-frame circuit breakers feature non-interchangeable trip units and are suitable for reverse feed applications where power flows from the bottom (load) to the top (line) terminals.
What type of mounting does the HED43B030L require?
This is a unit-mount, feed-thru circuit breaker. It is designed to be bolted directly to the chassis or backpan of compatible Siemens switchboards, motor control centers, and standalone enclosures, rather than plugging onto a busbar.
Is the trip unit on the HED43B030L adjustable?
No, this breaker features a fixed thermal and fixed magnetic trip unit (LI functions). The long-time and instantaneous trip settings are factory-calibrated and cannot be modified in the field.
