Description
Built for heavy-duty commercial environments, this 35A thermal-magnetic breaker ensures consistent overcurrent defense across three phases. The plug-on mounting style integrates smoothly into Square D NEHB panelboards without requiring complex modifications. Equipped with the signature Visi-Trip visual indicator, facility managers can easily spot faults during an outage. While part of a legacy lineup, it remains a crucial replacement part, often cross-referenced with the EHB34035 model.Specifications

Product FAQs
6 answersWhat panelboards are compatible with the EH34035?
The EH34035 is designed exclusively for use in legacy Square D NEHB panelboards. It features a plug-on mounting style that integrates directly into these specific distribution boards.
What is the difference between the EH34035 and the EHB34035?
Both are 35A, 3-pole breakers designed for Square D NEHB panelboards. The EH34035 features a plug-on mounting design, while the EHB34035 uses a bolt-on connection.
Can the EH34035 be installed on a 480V delta system?
No. The 480Y/277VAC rating indicates this breaker is only suitable for solidly grounded wye systems where the voltage to ground does not exceed 277V. It is not rated for ungrounded or corner-grounded 480V delta systems.
What wire sizes are accepted by the EH34035 terminals?
The terminal lugs on this breaker accept 14 to 2 AWG copper wire or 12 to 2 AWG aluminum wire. Ensure conductors are sized appropriately for the 35A rating and 75C temperature limits.
What type of fault protection does the EH34035 provide?
This breaker uses thermal-magnetic trip technology with fixed long-time and instantaneous (LI) functions. The thermal element protects against sustained overloads, while the magnetic element trips immediately during short circuits.
Is the EH series still actively manufactured by Square D?
The EH series and NEHB panelboards are considered legacy products by Schneider Electric. However, exact replacements like the EH34035 are still used to maintain existing NEHB distribution systems without requiring a full panel upgrade.
