Description
Built for commercial and industrial applications, the Siemens SJD69200NGT provides advanced electronic trip protection. It installs into Sentron panelboards, switchboards, and motor control centers as a unit-mount solution. This 3-pole, 200A MCCB handles 65kAIC at 240V and features a Sensitrip III unit with adjustable LSIG functions, including ground fault protection. For legacy upgrades, this model is replaced by the newer 3VA series, which requires a retrofit kit for proper integration.Specifications

Product FAQs
7 answersWhat does the NGT suffix mean in the SJD69200NGT catalog number?
The NGT suffix indicates the breaker includes a solid-state electronic trip unit with LSIG functions, which stands for Long-Time, Short-Time, Instantaneous, and Ground Fault. The G specifies that the ground fault protection is configured for 3-phase, 3-wire systems.
Can the SJD69200NGT be installed in a 3-phase, 4-wire system?
Yes, but applying this breaker in a 3-phase, 4-wire system requires a separate neutral sensor transformer. The standard ground fault protection is designed for 3-wire systems, so the fourth wire transformer is necessary for accurate ground fault monitoring.
Is the SJD69200NGT circuit breaker suitable for reverse feed applications?
Yes, standard interrupting SJD6 frame breakers are acceptable for reverse connection applications. This allows the breaker to be back-fed safely in compatible panelboards or switchboards.
What is the modern replacement for the legacy SJD69200NGT breaker?
The Sentron JD-frame series is often replaced by the newer Siemens 3VA series molded case circuit breakers. When upgrading an existing Sentron panelboard or switchboard to the 3VA series, a dedicated retrofit kit is required for proper mounting and bus connection.
What type of trip unit is equipped on the SJD69200NGT?
This breaker features a Sensitrip electronic trip unit with true RMS sensing. It allows electricians to precisely adjust the LSIG parameters to coordinate with other protective devices in the electrical system.
Which panels and enclosures accept the SJD69200NGT?
This unit-mount breaker is designed for use in Siemens Sentron panelboards, SMP switchboards, and motor control centers. It fits into spaces configured for 200A to 400A JD-frame devices.
Does the SJD69200NGT provide ground fault protection?
Yes, the LSIG trip unit includes adjustable ground fault protection. When installing this breaker, the ground fault system must be performance tested in accordance with NEC requirements for service equipment or feeder circuits.
