Schneider Electric EHB14020 Molded Case Circuit Breaker

The Square D (Schneider Electric) EHB14020 is a 1-pole, 20-amp molded‑case circuit breaker from the EHB Series, designed for 277-volt operation in electrical distribution panels. This bolt‑on, thermal‑magnetic MCCB delivers 14 kA short‑circuit interrupting capacity at 277V and is rated for a 40°C ambient, making it suitable for protecting individual branch circuits in commercial or light industrial panelboards. Its single‑pole, 1PH construction provides straightforward protection for a solitary circuit, with a bolt‑on mounting style that simplifies installation in compatible enclosures. The EHB14020 is typically used where Square D panel configurations require a compact 20A protective device, offering precise trip characteristics to isolate faults without unnecessary nuisance tripping. While variants exist in the EHB family (including Powerlink-equipped versions), this description covers the standard EHB14020 configuration.
