ABB / General Electric THQB1130HID Miniature Circuit Breaker

This Q-Line miniature circuit breaker is designed for use in GE A-Series panelboards. It features a bolt-on connection that secures directly to the panel busbar, providing a rigid and reliable connection for commercial and industrial applications.

The HID designation means the breaker is UL listed for High Intensity Discharge lighting applications. It is specifically calibrated to handle the high inrush currents generated by metal halide, high-pressure sodium, and mercury vapor lamps without nuisance tripping.

Both are 30A, 1-pole bolt-on breakers for GE A-Series panels. However, the THQB1130HID includes a specific UL listing for High Intensity Discharge lighting. This makes it the required choice for commercial HID lighting circuits, whereas the standard THQB1130 is intended for general purpose branch circuit protection.

This breaker is equipped with standard box lugs that accept 14 to 8 AWG copper conductors or 12 to 8 AWG aluminum conductors. Always torque the terminal screws to the manufacturer specifications printed on the breaker label to ensure a secure connection.

Yes, GE THQB breakers in the 20A to 60A range are UL listed as HACR type. This makes this 30A breaker suitable for protecting heating, air conditioning, and refrigeration motor loads in addition to its HID lighting rating.

The THQB1130HID uses a fixed thermal element to provide long-time delay protection against sustained overloads. It also includes a fixed magnetic element that provides instantaneous tripping to quickly clear severe short circuits.
