GE THHQB2190 - 90 A, 240 V, 2-Pole Bolt-On Circuit Breaker | AmpState

The GE THHQB2190 is a 90A, 240V, 2-pole bolt-on molded case circuit breaker built to deliver dependable branch circuit overcurrent and short-circuit protection in panelboards and load centers.

• Bolt-on mounting: provides a rigid, vibration-resistant bus connection for long-lasting reliability in demanding service environments.
• Thermal-magnetic trip unit: delivers stable, repeatable protection by combining overload (thermal) and short-circuit (magnetic) response for precise performance under real-world conditions.
• 2-pole, 90A, 240V rating: ensures simultaneous protection on both hot legs, ideal for circuits that require coordinated, robust safeguarding.
• OEM-compatible: designed to work with matching GE OEM load centers and panelboards, ensuring a seamless fit and listing compliance.
• Versatile for multiple environments: suitable for residential, commercial, and light industrial applications where reliable circuit protection is essential.

What it protects and where to use

• Provides branch circuit overcurrent and short-circuit protection in GE panelboards and load centers.
• Ideal for replacing a failing breaker or equipping a new installation that requires a 90-amp, 2-pole device.

Practical considerations and setup tips

Install the THHQB2190 per GE guidelines, and ensure mounting torque and wiring are appropriate for bolt-on installation. This 2-pole design ensures both legs trip together, helping to safeguard multi-wire circuits and protect downstream equipment and wiring from damage due to overcurrent or short circuits.
