Product FAQs
7 answersWhat does the "00S01" suffix indicate on the Siemens B345HH00S01?
The "00S01" suffix designates that this circuit breaker is factory-equipped with a 120VAC shunt trip accessory. This allows the breaker to be tripped remotely by applying a 120V control signal.
What does the "HH" in the B345HH00S01 catalog number signify?
The "HH" indicates that this is an HBL type breaker. HBL breakers feature an extra-high interrupting rating of 65kAIC at 240VAC, whereas standard BL breakers have a lower interrupting capacity.
Which panelboards are compatible with the Siemens B345HH00S01?
This breaker is designed for use in Siemens P1, P2, and P3 series panelboards. It requires a bolt-on connection and will not fit in standard residential load centers that use plug-in breakers.
What are the acceptable wire sizes for the lugs on this breaker?
The terminal lugs accept 8 to 6 AWG copper conductors or 8 to 4 AWG aluminum conductors.
How does the thermal-magnetic trip unit function on this breaker?
The fixed thermal-magnetic trip unit provides long-time (L) protection against sustained overloads and instantaneous (I) protection to quickly clear severe short circuits.
Is the B345HH00S01 part of the Siemens BL series?
Yes, this breaker is part of the Siemens BL family and utilizes a standard B frame. It is specifically classified as an HBL type due to its 65kAIC high interrupting rating.
Can this 3-pole breaker be used in a single-phase system?
No, this 3-pole breaker is designed for 3-phase electrical systems. Single-phase systems typically require 1-pole or 2-pole breakers.
