Part of the Sentron PD frame family, the Siemens SHPD69160 is a 1600A molded case circuit breaker with a Sensitrip III electronic trip unit. This unit-mount breaker is designed for Siemens S4 and S5 power panelboards, as well as SB-series switchboards. For newer installations, it is replaced by the 3VA6816-6HN31-0AA0 frame. Featuring adjustable Long-Time and Instantaneous (LI) trip functions, it provides a 65kAIC rating at 480VAC and current-limiting protection against severe faults.

Product FAQs
6 answers
Which Siemens enclosures are compatible with this PD-frame breaker?
The SHPD69160 is designed for installation in Siemens SB1, SB2, and SB3 switchboards, as well as Type S4 and S5 power panelboards.
What protection functions does the electronic trip unit provide?
The electronic trip unit features adjustable Long-Time (L) and Instantaneous (I) protection, allowing precise coordination for overloads and short circuits.
Which lug kit is typically used with this 1600A breaker?
The TA5P600 lug terminal kit is commonly used for line and load side connections on Siemens PD-frame 1600A circuit breakers, accepting 300 to 600 kcmil copper or aluminum wire.
How is the SHPD69160 installed in a panelboard?
This is a unit-mount, bolt-on circuit breaker. It must be bolted directly to the bus or mounting pan within a compatible enclosure, rather than snapping onto a DIN rail or plugging into a chassis.
Can this breaker replace older Sentron PD-frame models?
Yes, the SHPD69160 can serve as a replacement for older Siemens or I-T-E PD-frame breakers, such as the HPD69160, assuming the 65kA at 480V interrupting rating meets your facility requirements.
What safety precautions are required before adjusting the electronic trip settings?
Always de-energize and lock out the power supplying the switchboard or panelboard before accessing the breaker to adjust the trip unit settings or perform maintenance.
