Square D | JGL26150 | Circuit Breaker | 150A | 2-Pole | 600V

Square D JGL26150 Circuit Breaker delivers OEM-grade protection for demanding electrical systems. With a 150 amp rating, two-pole design, and a 600-volt maximum, this breaker is built to handle robust loads in commercial and light industrial panels. Use it for maintenance, retrofit, or replacement projects where precise compatibility matters and downtime is minimized.

Key specifications

• Amperage: 150 A
• Poles: 2-Pole (two hot legs share a common trip)
• Voltage rating: 600 V
• Part reference: JGL26150

Why choose this Square D model

• OEM compatibility: Designed to fit Square D panels that require the JGL-series style, reducing install guesswork and the risk of mismatch.
• Reliable protection for feeders and downstream equipment when paired with the appropriate panel.
• Direct replacement option to minimize electrical downtime during service or upgrades.

Ideal use cases

• Maintenance and service on existing Square D installations that specify JGL26150.
• Panel retrofit projects where a 2-pole, 150A, 600V breaker matches the system’s electrical protection needs.
• Replacement of aging or failed breakers in commercial or light industrial settings.

Practical compatibility notes

• Always confirm fit and ratings against your panel's labeling before ordering. The part number JGL26150 is the most reliable reference for compatibility.
• Check that your panel supports a 2-pole 150 A breaker with a 600 V rating and that the mounting/configuration matches the JGL family requirements.

With Square D engineering backing the design, this circuit breaker is built for consistent performance in demanding environments. Keep a spare on hand for planned maintenance or unexpected failures, and rely on the JGL26150 to protect both personnel and equipment when circuit conditions exceed safe levels.
