Product FAQs
7 answersCan the Siemens B230 replace older ITE or Gould circuit breakers?
Yes. Since Siemens acquired the ITE and Gould electrical lines, the Siemens B230 serves as the direct, UL listed replacement for legacy ITE and Gould Type BL 2-pole, 30A bolt-on breakers.
Will the B230 breaker fit in standard residential load centers?
No. The B230 is a Type BL bolt-on circuit breaker designed exclusively for commercial panelboards, specifically Siemens P1, P2, and P3 models. It cannot be installed in plug-on residential load centers.
Is the B230 circuit breaker HACR rated for HVAC applications?
Yes, this breaker is HACR rated. It is tested and approved to handle the specific inrush currents and operational demands of Heating, Air Conditioning, and Refrigeration equipment.
How does the thermal-magnetic trip mechanism function on this breaker?
The thermal-magnetic design provides two layers of protection. The thermal element responds to prolonged overloads by heating a bimetallic strip to break the circuit, while the magnetic element reacts immediately to clear severe short circuits.
What does the 10kAIC interrupting rating mean for this breaker?
The 10kAIC (Ampere Interrupting Capacity) rating indicates that the breaker can safely interrupt up to 10,000 amps of fault current at 120/240VAC without sustaining catastrophic internal damage or failing to open the circuit.
Does the B230 come with Insta-Wire terminals?
Yes, it features Siemens Insta-Wire technology. The load side lug screws are shipped backed out and ready for immediate wire insertion, which saves time during panel assembly and installation.
Are special precautions needed when connecting aluminum wire to this breaker?
The terminal lugs are dual-rated for both copper and aluminum conductors. When using aluminum wire (10 to 6 AWG), installers should apply an approved oxide-inhibiting joint compound to the stripped wire to prevent oxidation and ensure a secure, high-conductivity connection.
