Supplying 60 amps of reliable power distribution, the Square D EH24060 is a 2-pole molded case circuit breaker for commercial facilities. It features standard trip functions to handle overloads at 480Y/277VAC. This component utilizes a plug-on connection, making it compatible with legacy Square D NEHB panelboards. For modern upgrades, the bolt-on EHB24060 is the designated replacement. The breaker provides a 14kAIC rating and includes a Visi-Trip indicator to quickly spot tripped circuits.
What panelboards are compatible with the Square D EH24060?
The EH24060 is specifically designed for use in legacy Square D NEHB panelboards. It features a plug-on mounting design that connects directly to the NEHB busbar.
What is the difference between Square D EH and EHB circuit breakers?
The primary difference is the mounting style. EH breakers, like the EH24060, feature a plug-on connection, whereas EHB breakers utilize a bolt-on connection. Both are designed for NEHB panelboards, so you must verify your panel's specific mounting requirements before installation.
Can I replace the EH24060 with a modern EDB series breaker?
No. While EDB breakers are the modern equivalent for 480Y/277VAC applications, they are designed exclusively for Square D NF panelboards. They have a different form factor and will not mount into a legacy NEHB panelboard.
What wire gauge is accepted by the EH24060 terminals?
The integrated lugs on the EH24060 accept 14 to 2 AWG copper (Cu) wire or 12 to 2 AWG aluminum (Al) wire. Ensure proper torque specifications are followed during installation to maintain a secure connection and prevent overheating.
How can I tell if the EH24060 has tripped?
The EH24060 features a Visi-Trip indicator. When the breaker trips due to an overload or short circuit, the handle moves to a center position and a highly visible red indicator appears, allowing for quick identification of the faulted circuit.
What type of protection does the EH24060 provide?
This breaker utilizes a fixed thermal-magnetic trip unit. The thermal element provides long-time delay protection against sustained overcurrents, while the magnetic element delivers instantaneous protection against short circuits.
