ABB THQBB5FAAMAXXXX THQB2130 - 30A 2 Pole Miniature Circuit Breaker

This Q-Line bolt-on breaker is designed for installation in ABB and GE AQ Lighting Panels, as well as ReliaGear Panelboards. It requires a bolt-on bus and will not fit in standard plug-on load centers.

It utilizes a bolt-on mounting style. The breaker physically bolts directly to the panelboard bus connections, providing a highly secure and vibration-resistant contact suitable for commercial applications.

The box lugs accommodate 14 AWG to 8 AWG copper conductors, or 12 AWG to 8 AWG aluminum conductors.

Yes. Following ABB's acquisition of GE Industrial Solutions, Q-Line breakers may carry either the ABB or General Electric branding. They are identical in form, fit, and function.

THQB2130 is the standard catalog number for this 30A, 2-pole Q-Line breaker. THQBB5FAAMAXXXX is a specific factory variant SKU used for inventory and sourcing, but it represents the same physical breaker.

Yes. The internal common trip mechanism ensures that if an overload or short circuit occurs on either leg, both poles will open simultaneously to safely disconnect the entire circuit.

Yes, this breaker is UL listed for HACR (Heating, Air Conditioning, and Refrigeration) applications. It is commonly used for 30A dedicated circuits supplying water heaters, compressors, and small HVAC units.

Yes. The 2-pole configuration and common trip mechanism make it suitable for dedicated 240V loads as well as 120/240V multi-wire branch circuits, subject to local electrical codes.

The THQB2130 is the standard version with a 10 kAIC interrupting rating. The THHQB2130 is the high interrupting version, rated for 22 kAIC at 120/240V AC. Both share the same physical dimensions and bolt-on mounting style.

No. The THQB2130 features a fixed thermal-magnetic trip unit. Both the long-time overload and instantaneous short circuit trip functions are factory-set and cannot be adjusted in the field.
