Description
A drop-in replacement for discontinued Siemens and ITE power panelboards, this 1600A circuit breaker ensures continuous operation in demanding commercial environments. The three-pole, 600VAC unit utilizes a robust thermal-magnetic trip mechanism with fixed thermal and adjustable magnetic functions. It achieves a 65kA interrupting capacity at 240VAC and accommodates up to five 300-600 kcmil cables per phase using the TA5P600 lug kit. The HPX3B160 serves as its modern substitute.Specifications

Product FAQs
8 answersWhat lug kit is required to terminate cables on the HP3B1600 breaker?
This breaker accepts the TA5P600 lug kit, which accommodates up to five 300 to 600 kcmil aluminum or copper cables per phase.
Which panel types are compatible with the HP3B1600 breaker?
The HP3B1600 is designed for installation in Siemens switchboards and power panelboards that accommodate legacy KP/HP frame molded case circuit breakers.
Does the HP3B1600 feature an adjustable trip unit?
Yes, this breaker features a thermal magnetic trip unit with fixed thermal, or long-time, protection and an adjustable magnetic, or instantaneous, trip setting.
Can this breaker replace older ITE branded HP frame breakers?
Yes. Siemens acquired ITE and continued manufacturing the HP frame under the Siemens brand. The HP3B1600 directly replaces older ITE breakers with the exact same catalog number.
How does the HP3B1600 mount into a panelboard?
The HP3B1600 is a bolt-on molded case circuit breaker. It secures directly to the busbars in compatible Siemens power panelboards and switchboards using bolted connections.
Can I use aluminum wire with the HP3B1600?
Yes, when equipped with the TA5P600 lug kit, the breaker accepts either aluminum or copper conductors ranging from 300 to 600 kcmil.
What does the LI trip function code mean on this breaker?
The LI designation indicates that the thermal magnetic trip unit provides Long-Time (L) overload protection and Instantaneous (I) short-circuit protection.
What is the maximum number of conductors per phase for the HP3B1600?
When using the TA5P600 lug kit, this breaker can accept up to five conductors per phase, supporting large parallel cable runs for 1600A services.
