Designed for demanding industrial environments, this 100% rated 200A Sentron JD-frame breaker delivers comprehensive LSIG (Long-Time, Short-Time, Instantaneous, Ground-Fault) protection. It mounts into Siemens P4 and P5 panelboards, providing robust unit-mount integration for heavy-duty commercial systems. The microprocessor-based solid-state trip unit ensures highly accurate fault sensing and configurable coordination, backed by a high interrupting capacity of 65kAIC at 480VAC.
Can the SHJD69200NGTH be wired for reverse feed applications?
No. While standard SJD6 frames are approved for reverse connection, the high-interrupting SHJD6 series is not acceptable for reverse feed applications.
Which panelboards are compatible with the SHJD69200NGTH?
This unit is designed for Siemens P4 and P5 panelboards, as well as Siemens switchboards. When using the appropriate branch mounting kit, it requires 8.75 inches of unit space.
Do I need additional components to use this breaker on a 4-wire system?
Yes. Out of the box, this device is configured for 3-phase, 3-wire systems. To properly use the ground fault protection on a 3-phase, 4-wire system, you must install an external neutral sensing transformer.
What do the NGT and H suffixes indicate in the SHJD69200NGTH catalog number?
In the Sensitrip solid-state catalog logic, the NGT suffix designates the adjustable trip functions, meaning it includes Long-Time, Short-Time, Instantaneous, and Ground-Fault (LSIG) settings. The final H suffix indicates that the circuit breaker is 100-percent continuous rated.
Is performance testing required for the ground fault protection on this breaker?
Yes. The National Electrical Code requires that a simulated low-voltage, high-current test be performed on integral ground fault protection systems by qualified personnel during initial installation to ensure proper operation.
