Square D GV3A07 - 5 A Circuit Breaker | AmpState

Square D GV3A07 is a 5A molded case circuit breaker designed to deliver dependable branch circuit overcurrent and short-circuit protection in panelboards and loadcenters. Built for real-world electrical environments, it combines space efficiency with precise protection you can trust.

• Compact molded case design optimizes panel space, making it easier to fit more circuits and organize wiring in crowded panels.
• Thermal-magnetic trip unit delivers stable, repeatable protection by responding to both overloads (thermal) and short circuits (magnetic), helping reduce nuisance trips while maintaining safety.
• 5 A amperage rating is ideal for low-current branch circuits such as lighting, outlets, or control circuits within residential, commercial, and light industrial applications.
• OEM compatibility is designed to work with matching Square D OEM loadcenters and panelboards, ensuring consistent performance and seamless integration.
• Versatile, code-friendly protection suitable for multiple settings—from home subpanels to small commercial distributions and light industrial panels.

How it protects your system

A molded case breaker like the GV3A07 blends a thermal element with a magnetic trigger. Under normal load, the thermal path handles gradual heating. If a circuit is overloaded for an extended period, the thermal element trips to interrupt the circuit. In a short-circuit event, the magnetic mechanism kicks in instantly to cut off fault current, safeguarding conductors and connected equipment.
