Square D EJB26080 80A 2-Pole 600 V Circuit Breaker

Square D EJB26080 80A 2-Pole 600 V Circuit Breaker delivers reliable overcurrent protection for demanding electrical installations. With an 80-amp rating and a two-pole design, this unit safeguards both hot conductors in a 240-volt circuit while supporting systems up to 600 V. Part number EJB26080 identifies this specific device in Square D’s protective lineup, ensuring precise ordering and compatibility within your panel architecture.

Why this circuit breaker matters

When a circuit experiences an overload or a short circuit, the EJB26080 trips to disconnect power, helping protect wiring, devices, and equipment from damage. The 2-pole configuration ensures simultaneous disconnection of both live conductors, a critical safety feature for 240 V circuits common in commercial and light industrial settings. The 600 V rating expands its applicability to higher‑voltage distribution environments, giving you a single component that covers a broad range of protective needs.

Key specifications

• Current rating: 80 A
