GE THHQB32030 - 30 A, 240 V, 3-Pole Bolt-On Circuit Breaker | AmpState

GE THHQB32030 is a 30A, 240V, 3-pole bolt-on molded case circuit breaker engineered to deliver dependable branch circuit overcurrent and short-circuit protection in panelboards and loadcenters. Built for reliable performance in a variety of settings, this unit is ready to upgrade or replace existing protection without sacrificing compatibility.

• Secure bolt-on mounting: a rigid, vibration-resistant bus connection that stays tight under operating conditions, helping maintain consistent electrical contact and reducing the risk of loose connections over time.
• Thermal-magnetic trip unit: combines thermal (overcurrent) and magnetic (short-circuit) protection for stable, repeatable protection performance across temperature and load variations.
• OEM-compatible design: specifically engineered to work with matching GE OEM load centers and panelboards for a seamless replacement or upgrade experience.
• Versatile for multiple environments: suitable for residential, commercial, and light industrial applications where reliable 30A, 240V protection is required.
