Product FAQs
6 answersWhich panelboards are compatible with the EF2B060 circuit breaker?
This unit mount breaker is designed for installation in classic ITE and Siemens FC, FCI, and CDP panelboards. It bolts directly to the bus or mounting pan without requiring aftermarket adapters.
What wire sizes and materials are accepted by the load side lugs on the EF2B060?
The factory-installed load side lugs accept 10 AWG to 1/0 AWG copper or aluminum wire. Always verify proper torque specifications during installation to ensure a secure connection.
Can the EF2B060 be used in direct current (DC) applications?
Yes, this breaker is rated for DC applications up to 250VDC, providing an interrupting capacity of 10kAIC at that voltage.
Is the EF2B060 an obsolete breaker, and what is its modern equivalent?
The EF frame is a legacy ITE and Siemens product line. While exact replacements like the EF2B060 are still sourced for existing CDP and FC panels, modern ED frame breakers such as the ED62B060 serve as the current generation equivalent.
Does the EF2B060 feature an adjustable trip unit?
No, it features a non-interchangeable thermal magnetic trip unit with fixed long time and instantaneous trip functions. It cannot be adjusted in the field.
How does the EF2B060 mount inside the enclosure?
It is a bolt-on, unit mount circuit breaker. It is secured using mounting hardware directly to the panelboard chassis rather than snapping onto a DIN rail or plug-in bus.
