GE THQB2130 30A 2 Pole 120/240V AC Circuit Breaker

SKU CH-2RYM-GH2YE

A 30 A, two-pole bolt-on breaker rated 120/240 V AC with a 10 kA interrupting capacity for load-center mounting

  • 30 A rating protects 120/240 V AC circuits
  • 10 kA interrupting capacity handles fault currents safely
  • Bolt-on mounting fits THQB load centres directly
  • Screw-clamp terminals accept 14 to 8 AWG copper wire
  • Compact 3.5 in frame saves panel space

GE THQB2130 30A Circuit Breaker

The GE THQB2130 is a standard bolt-on circuit breaker rated at 30 amps for 120/240V AC single-phase systems. It uses a toggle actuator and provides a 10kA interrupting rating at the rated voltage. This two-pole device fits THQB series load centres and lighting panels. It is not suited for DC applications or panels requiring plug-in style breakers.

Thermal and Power Characteristics

The breaker carries a continuous 30A load within the 100A frame size during normal operation. Its toggle mechanism provides a clear visual indication of the on, off, or tripped state without auxiliary contacts. Power dissipation follows standard thermal-magnetic trip curves for the THQB series design. No active cooling or noise-generating components are present in this passive protection device.

Build Quality and Mounting Implications

The bolt-on mounting style secures the breaker directly to the panel bus with screws for a stable connection in vibration-prone environments. Screw-clamp terminals accept copper wire from 14 MCM up to 8 MCM and aluminium wire from 12 MCM up to 8 MCM. The compact frame measures 3.5 in length, 1 in width, and 3.3 in depth to fit standard panel cavities. Buyers needing plug-in installation or DC voltage ratings should select a different model.

Questions about this item

How do I install the bolt-on THQB2130 breaker in a lighting panel, and what is the common torque mistake?

Mount the breaker onto the panel bus using the bolt-on hardware, then secure the load conductors in the screw-clamp terminals; the step often missed is tightening the clamp screws to the specified torque for 14 MCM copper or 12 MCM aluminium wire.

What maintenance or replacement will the THQB2130 breaker need over its service life?

The breaker itself is a non-serviceable unit; plan to replace it if the toggle fails to latch, if it trips at currents well below 30 A, or after it has interrupted a fault near its 10 kA interrupting rating.

What is the first limit reached when the THQB2130 runs continuously at 30 A in a 100 A frame load center?

The 30 A thermal trip curve is the first limit; sustained current at or above 30 A will cause the breaker to open, while the 100 A frame and 10 kA interrupting capacity remain unused.
