Compatibility

Designed for use with compatible Square D / Schneider Electric NEHB panelboards and electrical distribution equipment approved for EHB Series circuit breakers.

The EHB34020 is intended for 3-phase, 480Y/277V AC applications and provides thermal-magnetic overload and short-circuit protection. Its bolt-on mounting configuration and E-Frame design allow installation in compatible electrical distribution equipment.

Important: The EHB34020 is designed for legacy NEHB panelboards. Newer Square D EDB, EGB, and EJB breakers are not automatically direct replacements because panelboard mounting and compatibility requirements may differ.

Always verify the specific panelboard model, approved breaker type, voltage, pole configuration, interrupting rating, conductor size, and manufacturer requirements before installation.
