GE THQB2125 - 25 A, 240 V, 2-Pole Bolt-On Circuit Breaker | AmpState

The GE THQB2125 is a bolt-on molded case circuit breaker engineered for dependable branch-circuit overcurrent and short-circuit protection in panelboards and load centers. With a 25-amp rating at 240 volts and a robust 2-pole design, this unit delivers reliable, simultaneous disconnection of both hot legs for enhanced safety on 240V circuits.

Why this breaker stands out

• Secure bolt-on mounting provides a rigid, vibration-resistant bus connection, helping maintain consistent electrical performance in environments with vibration or movement.
• Thermal-magnetic trip unit delivers stable, repeatable protection by responding to both overload and short-circuit conditions, reducing nuisance trips and protecting connected equipment.
• Direct compatibility with matching OEM load centers and panelboards means straightforward installation and fewer compatibility concerns during replacements or upgrades.
• 2-pole design ensures simultaneous disconnection of both conductors, which is crucial for safeguarding 240V circuits and improving overall electrical safety.
• molded-case durability—tested for the rigors of residential, commercial, and light-industrial use while delivering dependable protection for a range of circuits.

Ideal applications and use cases

Designed for a variety of installation scenarios, the THQB2125 is a solid choice for:

• Residential panelboards needing reliable 25A protection on 240V circuits, such as HVAC control circuits, water heaters, or multi-wire branch circuits that require a two-pole disconnect.
• Commercial spaces with load centers that demand robust protection for lighting, receptacle, and small-equipment circuits wired at 240V.
• Light-industrial environments where a durable, bolt-on breaker provides steady protection against both overloads and short circuits in panel assemblies.

What problems does it solve?

By combining a secure bolt-on mount with a thermal-magnetic trip unit, this breaker minimizes vibration-related wear and delivers predictable tripping behavior. The two-pole configuration prevents creating hazardous potential differences during fault conditions, protecting both wiring and equipment while simplifying safety procedures during maintenance or replacement.
