Product FAQs
6 answersWhat panelboards are compatible with the EB1040?
As an E-Frame device, this breaker is engineered to bolt directly onto the bus of Eaton Pow-R-Line C panelboards and legacy Westinghouse F-Frame distribution panels.
Can the EB1040 be used as a substitute for an EHD1040?
Yes, the EB1040 is a recognized direct replacement for the EHD1040. Both are E-Frame devices that share the same physical dimensions and bolt-on mounting configuration.
What type of wire connections does the EB1040 support?
The breaker includes a load-side lug that accepts 14 to 1/0 AWG aluminum or copper wire. The line side uses a bolt-on connection to attach directly to the panelboard bus.
Is the EB1040 suitable for direct current applications?
Yes, this breaker is dual-rated for alternating current and direct current. It can safely interrupt faults in 125VDC systems, making it suitable for specific industrial DC control circuits.
Are the trip settings on the EB1040 adjustable?
No, this breaker features a fixed thermal-magnetic trip unit. Both the long-time and instantaneous trip functions are factory set and cannot be field adjusted.
Can the EB1040 be locked out for maintenance?
Yes, the toggle on this breaker is compatible with standard single-pole lockout devices, including Brady 65396 and 51254 models, to ensure compliance with lockout-tagout safety procedures.
