Description
Handling severe fault conditions, this 35-amp HBL series breaker delivers an extra-high 65kAIC interrupting capacity at 240VAC for demanding industrial environments. The three-pole unit mounts into Siemens P1, P2, P3, P4, and P5 panelboards, utilizing a quick-make/quick-break mechanism to ensure rapid arc extinguishment. It features a trip-free design that prevents the contacts from being held closed during a fault, while providing reliable thermal-magnetic protection for heavy-duty loads.Specifications

Product FAQs
6 answersWhich panelboards accept the Siemens B335HH circuit breaker?
This bolt-on breaker is specifically designed for installation in Siemens P1, P2, P3, P4, and P5 commercial panelboards. It is not compatible with standard residential load centers that require plug-on breakers.
What is the difference between the Siemens B335, B335H, and B335HH?
While all three are 35-amp, 3-pole bolt-on breakers, their interrupting ratings differ. The standard B335 (BL series) is rated for 10kAIC, the B335H (BLH series) is rated for 22kAIC, and the B335HH (HBL series) provides an extra-high 65kAIC rating at 240VAC for systems with higher available fault currents.
Is the Siemens B335HH a direct replacement for legacy ITE breakers?
Yes. Siemens acquired ITE and maintains backward compatibility for their panelboard breakers. The B335HH serves as the direct replacement for older ITE 35-amp, 3-pole HBL series bolt-on breakers.
Does the B335HH breaker have a trip-free mechanism?
Yes, this breaker features a trip-free toggle mechanism. This safety feature ensures the breaker will open the circuit during an overload or short-circuit fault, even if the handle is physically held or locked in the ON position.
Are the load-side lugs included with the B335HH?
Yes, the breaker comes factory-equipped with load-side lugs. When terminating your conductors, ensure you use the proper 10 to 6 AWG copper or aluminum wire and torque the connections to the manufacturer specifications printed on the breaker label.
Can the B335HH be mounted on a standard DIN rail?
No, the B335HH is a bolt-on molded case circuit breaker designed exclusively for busbar mounting in Siemens P-series panelboards. It does not support DIN rail installation.
