Square D EJB26020 20A 2-Pole 347 V Circuit Breaker

Designed by Square D for demanding commercial electrical systems, the EJB26020 20A 2-Pole 347 V Circuit Breaker delivers dependable protection where 347-volt distribution is in use. With a two-pole design, it interrupts both live conductors, ensuring a coordinated shutoff that safeguards wiring and connected equipment against overloads and short circuits. This specific 20-amp, 347-volt device is a precise fit for installations that require robust overcurrent protection without compromising panel space or performance.

Key specifications

• Brand: Square D
• Part Number: EJB26020
• Current rating: 20 A
• Poles: 2
• Voltage rating: 347 V

Why this 2-pole breaker stands out

The dual-pole design ensures both hot lines are disconnected simultaneously during a fault, reducing the risk of backfeed and improving safety on 347 V circuits. A 20 A rating targets common commercial loads—such as lighting circuits, small equipment, and branch circuits—while the 347 V rating aligns with specific building distribution needs. Built to fit Square D panels that accept EJB-series devices, this breaker provides consistent, repeatable protection you can rely on in daily operations.

Ideal use scenarios

• Replacing a failing 2-pole breaker in commercial panels serving lighting or small equipment on 347 V systems.
• Protecting branch circuits in offices, retail spaces, educational facilities, or healthcare environments that utilize 347 V distribution.
• Situations requiring coordinated interruption of both hot legs for safety, compliance, and reduced arcing risk.

Installation and compatibility tips

Ensure you install this breaker in a panel that accepts Square D EJB-series devices and that your system voltage matches 347 V. Always follow the panel manufacturer’s guidelines for installation torque and alignment to guarantee reliable operation. After replacement, clearly label the circuit and verify functionality with a proper test procedure conducted by qualified personnel.

For reliable protection in 347 V commercial installations, the Square D EJB26020 20A 2-Pole 347 V Circuit Breaker delivers precise, coordinated safety for your critical circuits while maintaining compatibility with your existing Square D distribution panels.
