Schneider Electric EHN3-CL Circuit Breaker Adapter

Schneider Electric's EHN3-CL circuit breaker adapter is a three-pole mounting base designed to accept EH and EHB family breakers in Square D panels, providing a secure, factory-proven fit for modular overcurrent protection in commercial and industrial enclosures. This adapter is commonly paired with EHB-series breakers, and the included EHB14020 unit is a 20A, single-pole molded-case breaker compatible with 277 VAC circuits; the EHB14020 spec lists a 14 kA interrupting rating at 277 V. The combination delivers a three-pole assembly by mounting EHB-style breakers onto the EH/EHB base, ensuring proper alignment with the bus and mounting hardware. The EHN3-CL base maintains Schneider Electric's standard mounting interface for EH/EHB devices, enabling straightforward installation and reliable electrical continuity across the three poles in multi-pole protection configurations.
