Description
Manufactured by Siemens, the SLD6A600LIG delivers 600A of electronic trip circuit protection. Built for heavy-duty industrial environments, it ensures reliable power distribution. This unit-mount breaker installs into Sentron P4 and P5 panelboards, switchboards, and motor control centers. It is a legacy component replaced by the 3VA series via retrofit. Lugs are not included. Rated 35 kAIC at 480V, it utilizes a Sensitrip IV trip unit with adjustable LIG settings and reverse feed capability.Specifications

Product FAQs
6 answersWhich Siemens enclosures are compatible with the SLD6A600LIG?
This breaker is designed for installation in Siemens Sentron Type P4 and P5 panelboards, as well as compatible Siemens switchboards and motor control centers.
What specific faults does the LIG trip unit protect against?
The solid-state electronic trip unit provides adjustable protection for Long-Time (standard overloads), Instantaneous (high-level short circuits), and Ground-Fault (leakage to ground) conditions.
Does the SLD6A600LIG include short-time delay protection?
No. The LIG designation indicates it only includes Long-Time, Instantaneous, and Ground-Fault functions. If your coordination study requires short-time delay, you will need a breaker with an LSI or LSIG trip unit instead.
What is the difference between an LD6 and an SLD6 frame?
Both belong to the Siemens Sentron LD frame family. The SLD prefix indicates the breaker uses a solid-state electronic trip unit, whereas standard LD6 breakers use fixed thermal-magnetic trip units.
How many conductors can the standard lugs on this breaker accept?
The factory lugs accommodate two conductors per phase. The accepted wire range is 3/0 AWG to 500 kcmil for either copper or aluminum wire.
Does this breaker provide ground-fault equipment protection?
Yes. The G in the LIG trip unit designation indicates it includes integrated ground-fault protection. This allows you to adjust pickup and delay parameters to protect downstream equipment from damaging ground faults.
