Information About EJB34125
The EJB34125 is part of the Schneider Electric Square D EJB Series, developed for compact molded case circuit breaker applications in panelboard systems. This breaker supports three-phase electrical distribution with a continuous current rating of 125 amps at 480Y/277VAC. It uses a thermal magnetic trip mechanism to provide coordinated overload and short-circuit protection through long-time and instantaneous response. The bolt-on mounting design allows secure installation in NF panelboards while maintaining consistent electrical performance.
Key Features
- Thermal Magnetic Protection: Combines thermal overload sensing with instantaneous magnetic tripping to protect circuits from sustained overcurrent and short-circuit faults.
- High Interrupting Capacity: Rated at 65 kAIC at 480Y/277 VAC, enabling safe interruption of high fault currents in demanding distribution systems.
- Three Pole Configuration: Provides balanced protection across all phases for stable three-phase power distribution.
- Bolt-On Mounting Design: Ensures secure mechanical and electrical connection within compatible panelboards.
- EJB Compact Frame: Optimized for space-efficient installations while maintaining robust electrical performance.
- Wide Conductor Compatibility: Accepts a broad range of aluminum and copper wire sizes to support flexible field wiring.
- Certified for Industrial Use: cULus listed and HACR rated for compliance with recognized electrical and safety standards.
The EJB34125 delivers the reliability and precision required for protecting three-phase branch circuits in commercial and industrial power distribution systems.
