Description
Designed for maximum coordination, the Siemens SHLD69600NGT is a 3-pole, 600A electronic trip breaker in the Sentron LD frame. This bolt-on MCCB installs into Siemens Sentron panelboards, switchboards, and motor control centers. It is replaced by the 3VA6460-6JQ31-0AA0 using a strap kit. The Sensitrip III unit offers adjustable long-time, short-time, instantaneous, and ground fault (LSIG) settings. It features true RMS sensing, a visual trip indicator, and a 65kAIC rating at 480VAC.Specifications

Product FAQs
4 answersWhat does the NGT suffix designate on the SHLD69600NGT catalog number?
The NGT suffix indicates the breaker is equipped with a solid-state Sensitrip electronic trip unit featuring LSIG (Long-Time, Short-Time, Instantaneous, and Ground-Fault) functions. This replaces fixed thermal-magnetic elements with precise, field-adjustable trip coordination.
Can the Siemens SHLD69600NGT be reverse fed?
No. According to Siemens catalog specifications, while standard SLD6 frames support reverse feeding, the high-interrupting SHLD6 frame is not acceptable for reverse connection applications. The line and load connections must remain strictly oriented.
Does this breaker require a separate relay for ground fault protection?
No. The built-in LSIG electronic trip unit includes integrated equipment ground-fault protection. Electricians can adjust the ground-fault pickup and delay settings directly on the front of the breaker without installing external sensing relays.
Can this breaker replace older thermal-magnetic LD-frame models?
Yes. It shares the standard Siemens Sentron LD-frame footprint. It will physically mount in the same space as older thermal-magnetic SHLD6 breakers, allowing you to upgrade an existing panel or switchboard to solid-state LSIG protection.
