Description
Built for demanding industrial environments, the SHLD69500G is a 500A, 3-pole MCCB from the Siemens Sentron LD-frame series. It provides robust power distribution and advanced circuit protection. This bolt-on breaker installs into Siemens Sentron panelboards and switchboards. For legacy upgrades, it is replaced by the 3VA6450-6HM31-0AA0 using a strap kit. Equipped with a Sensitrip III electronic trip unit, it delivers LIG protection with a 65kAIC rating at 480VAC and true RMS sensing.Specifications

Product FAQs
6 answersWhat equipment is compatible with the SHLD69500G circuit breaker?
This breaker is designed for installation in Siemens Sentron panelboards, switchboards, and motor control centers.
What do the LIG trip functions represent on this breaker?
LIG stands for Long-Time, Instantaneous, and Ground Fault. This solid-state electronic trip unit allows you to adjust these specific parameters to coordinate with your electrical system.
What is required to use the ground fault protection on a 4-wire system?
When installing this breaker on a 3-phase, 4-wire system, you must connect a compatible external neutral sensor to the trip unit. This ensures the breaker accurately measures neutral return currents for the ground fault logic.
Is the SHLD69500G a 100 percent rated circuit breaker?
No, this is a standard 80 percent rated breaker. Per electrical code, continuous loads lasting three hours or more must not exceed 80 percent of its 500A rating, which is 400A.
How does the SHLD69500G differ from an HLD69500 breaker?
The SHLD69500G features a solid-state electronic trip unit with ground fault protection. A standard HLD69500 uses a traditional thermal-magnetic trip unit. Both share the same physical LD frame dimensions and mounting footprint.
What wire sizes are accepted by the standard lugs for this breaker?
When equipped with standard mechanical lugs, the breaker accepts two 3/0 AWG to 500 kcmil copper or aluminum conductors per phase.
