Square D QO360 60A 3-Pole Thermal-Magnetic Circuit Breaker

The Square D QO360 Circuit Breaker is a high-performance 60-amp, 3-pole device engineered for dependable overcurrent protection in residential and commercial systems. Designed within the QO Series, it offers rapid thermal-magnetic response and includes the Visi-Trip indicator for quick identification of tripped circuits.

Why It Helps
Its plug-in mounting style enables quick installation into compatible Square D QO load centers and NQ panelboards, reducing downtime and simplifying service work. The breaker’s Qwik-Open mechanism adds an extra layer of safety by reacting faster than standard breakers during electrical faults.

Key Highlights

• The built-in Visi-Trip indicator uses a bright red window to clearly identify tripped conditions, improving troubleshooting efficiency in active electrical systems.
• Thermal-magnetic protection guards against both overloads and short circuits, providing reliable circuit defense for demanding residential and commercial loads.
• Plug-in construction supports fast installation and replacement inside QO and NQ/NQOD panels without additional mounting hardware.
• UL Listed, CSA Certified, and HACR rated to meet rigorous safety and performance requirements.
• Trip-free toggle mechanism ensures consistent operation and prevents the breaker from being held in the ON position during a fault.

Applications
Well-suited for feeder circuits, large appliances, light commercial systems, and three-phase installations requiring 60-amp protection. Its robust construction and fast response make it a practical and reliable choice for panels built on Square D’s QO and NQ/NQOD platforms.
