Product FAQs
8 answersWhat enclosures or panels are compatible with the EHD1050L?
This F-Frame breaker is designed for use in Eaton Series C panelboards, switchboards, and standalone enclosures. It is a unit-mount, feed-thru breaker and does not plug onto a busbar.
Can I use the EHD1050L to replace an older F-Frame breaker?
Yes, the EHD1050L shares the standard Series C F-Frame footprint and can replace older 1-pole F-Frame breakers like the FDB1050 or FD1050 in existing panelboards and motor control centers.
Can the EHD1050L be used in DC applications?
Yes, in addition to its AC ratings, this breaker is rated for 125VDC with an interrupting capacity of 10kAIC, making it suitable for direct current control circuits.
Is the EHD1050L HACR rated?
Yes, this breaker is HACR rated, meaning it is approved for use with heating, air conditioning, and refrigeration equipment.
What wire sizes do the lugs on the EHD1050L accept?
The included line and load lugs accept 14 AWG to 1/0 AWG copper or aluminum wire.
Does the EHD1050L mount directly to a busbar?
No, this is a unit-mount, feed-thru circuit breaker. It requires cable-in and cable-out connections rather than bolting or plugging directly onto a panelboard bus.
What is the difference between the EHD1050 and the EHD1050L?
The breakers are identical. The L suffix in the EHD1050L catalog number indicates that the breaker is factory-packaged with standard line and load lugs.
What does the LI trip function code indicate?
The LI code stands for Long-Time and Instantaneous. This means the breaker uses a standard fixed thermal and fixed magnetic trip unit to provide both overload and short-circuit protection.
