Product FAQs

9 answers
Which Siemens panelboards accept the B130 circuit breaker?

The B130 is specifically designed for use in Siemens P1, P2, P3, P4, and P5 series commercial panelboards. It is not compatible with standard residential load centers.

Can I use the B130 in a Square D or Eaton panelboard?

No. The Siemens B130 is strictly UL listed for use in compatible Siemens, as well as legacy ITE and Gould, commercial panelboards. Mixing breaker brands outside of manufacturer approved configurations violates the UL listing.

Can I install this breaker in a residential Siemens load center?

No. The B130 is a Type BL bolt-on circuit breaker designed for commercial panelboards. Standard residential Siemens load centers typically require Type QP plug-in breakers, such as the Q130, instead,.

Does this breaker replace older ITE or Gould B130 models?

Yes. Siemens acquired the ITE and Gould circuit breaker lines. A modern Siemens B130 is the direct, manufacturer approved replacement for vintage ITE or Gould B130 breakers,.

What is the difference between a Siemens B130 and a Q130 breaker?

While both are 30-amp, single-pole breakers, their mounting styles differ. The B130 is a Type BL bolt-on breaker for commercial panelboards, whereas the Q130 is a Type QP plug-in breaker meant for standard residential load centers,.

What does the "LI" trip function mean on this breaker?

"LI" stands for Long-Time and Instantaneous. The long-time function provides delayed tripping for mild, continuous overloads, while the instantaneous function trips the breaker immediately during a severe short circuit.

Is the B130 breaker HACR rated for HVAC equipment?

Yes. It carries an HACR rating, making it suitable for heating, air conditioning, and refrigeration applications where high starting currents are normal.

Does this breaker offer arc fault (AFCI) or ground fault (GFCI) protection?

No. The B130 is a standard thermal-magnetic circuit breaker that provides overload and short-circuit protection. It does not include built-in AFCI or GFCI safety functions.

Is the B130 a plug-in or bolt-on circuit breaker?

The B130 (Type BL) is strictly a bolt-on circuit breaker. It is secured directly to the panelboard bus bar using mounting screws, providing a robust, vibration-resistant connection ideal for commercial environments.
