Schneider Electric EHB34020 Three-Pole Circuit Breaker

Schneider Electric's Square D EHB34020 is a three-pole molded-case circuit breaker (MCCB) in the EHB family, rated for 20 A at 480Y/277 VAC. Built for bolt-on mounting in compatible switchgear, it uses thermal-magnetic protection to guard three-phase feeders and loads from overloads and short circuits. With an interrupting capacity of 14 kA at 277 V, the EHB34020 provides reliable protection in commercial and light industrial power distribution, and is specified for operation in ambient up to 40°C. This device belongs to Schneider Electric's EHB frame and is designed for rugged performance in demanding environments, delivering precise overcurrent protection while preserving system uptime. The EHB34020 is explicitly identified as a 3P, 20A, 480Y/277V MCCB from Square D, suitable for applications requiring three-phase protection in high-voltage distribution networks, where space constraints necessitate a compact, bolt-on solution.
