Product FAQs
5 answersWhat equipment is the Heinemann 2911 circuit breaker designed for?
This 2-pole breaker is engineered for use in compatible Heinemann panels and specific OEM equipment that requires a unit-mounted, feed-thru configuration.
What wire sizes are compatible with the terminals on this breaker?
The screw and clamp terminals on the 2911 are designed to accept wiring ranging from 8 AWG to 2 AWG.
How is the 2911 breaker installed in a panel?
It utilizes a unit mount design with a feed-thru connection type. Instead of snapping or bolting onto a standard busbar, the line and load connections are hardwired directly to the breaker terminals.
How does the hydraulic-magnetic trip mechanism operate in this breaker?
The hydraulic-magnetic technology provides fixed Long-Time and Instantaneous (LI) trip functions. Because it relies on magnetic flux rather than thermal elements, the trip characteristics remain stable and are largely unaffected by ambient temperature fluctuations.
Does this breaker allow for adjustable trip settings?
No, the Long-Time and Instantaneous trip functions on the 2911 are fixed and cannot be field adjusted.
