Square D By Schneider Electric EJB14050 Circuit Breaker

Square D by Schneider Electric EJB14050 is a 1-pole, 50-amp, 480-V bolt-on circuit breaker in the Square D E-Frame family. It uses a thermal-magnetic trip mechanism to provide overload protection and short-circuit protection for 480Y/277 VAC service, and is designed for panelboard or switchgear installations that accept E-Frame bolt-on devices. For wiring, the unit supports aluminum conductors from #12 to #6 and copper conductors from #14 to #6, with standard lug ranges compatible with these gauges. As a single-pole device, it interrupts a single live conductor and is intended to protect individual circuits in compatible Square D assemblies. This EJB14050 replacement part is suitable for use in existing Square D installations that require a 50-amp bolt-on breaker within 480Y/277 VAC electrical systems, ensuring consistent protection aligned with the E-Frame design language.
