Technical specifications at a glance

• Manufacturer: Square D
• Part Number: QHB130
• Type: Thermal-magnetic molded case circuit breaker
• Amperage Rating: 30 A
• Number of Poles: 1
• Mounting Style: Bolt-on

Why bolt-on matters in real-world setups: in panels where vibration, equipment movement, or long service life are concerns, bolt-on mounting provides a sturdier bus connection and reduced risk of connection degradation. This translates to fewer false trips and more predictable protection for the circuits that power your home or business.

Ideal use cases and installation notes

• Install in panelboards or load centers that specify bolt-on breakers for secure, durable operation.
• Use for dedicated 30A circuits within residential, commercial, or light industrial electrical distributions that require reliable overcurrent and short-circuit protection.
• Pair with matching Square D panels to maintain listing, compatibility, and optimal performance.

In short, the Square D QHB130 30A, 1-pole bolt-on circuit breaker is a purpose-built solution for dependable branch-circuit protection. Its secure mounting, precise thermal-magnetic protection, and OEM-aligned design make it a smart, long-lasting choice for protecting your electrical distribution—whether you’re upgrading a panel, replacing a failed unit, or expanding a small-scale system.
