Description
Built for heavy-duty environments, the Siemens SHLD69600G is a 3-pole, 600A electronic trip breaker from the Sentron LD frame series. This bolt-on MCCB mounts into Siemens Sentron panelboards, switchboards, and motor control centers. For system upgrades, it is replaced by the 3VA6460-6HM31-0AA0 using a strap kit. Featuring the Sensitrip III unit, it provides adjustable long-time, instantaneous, and ground fault (LIG) protection. It delivers a 65kAIC rating at 480VAC.Specifications

Product FAQs
8 answersWhat is the standard lug configuration for the SHLD69600G?
This breaker accepts two conductors per phase. The standard wire range accommodates 3/0 AWG to 500 kcmil for both copper and aluminum conductors. Ensure proper torque specifications as listed on the breaker label during installation.
Which Siemens enclosures are compatible with this breaker?
This LD frame breaker is designed for use in Siemens Sentron panelboards, switchboards, and motor control centers that are configured to accept bolt-on SLD or LD frame breakers.
How is the electronic trip unit configured on the SHLD69600G?
It features a solid state electronic trip unit with LIG functions. This provides adjustable settings for Long-Time (overload), Instantaneous (short circuit), and Ground Fault protection. Note that this specific model does not include Short-Time delay.
Does the ground fault function on this breaker provide personnel protection?
No. The ground fault function in this electronic trip unit provides Ground Fault Protection of Equipment (GFPE), not Class A personnel protection. It is designed to protect electrical systems from damaging low-level ground faults.
What does the 'S' in the SHLD69600G catalog number indicate?
The 'S' designates a solid state (electronic) trip unit. Standard HLD breakers use thermal-magnetic trip units, while the SHLD series utilizes an electronic trip unit for more precise adjustability and advanced functions like ground fault protection.
Can the SHLD69600G replace a standard HLD69600 breaker?
Yes, it shares the same physical LD frame dimensions and bolt-on mounting configuration. However, the SHLD69600G features an electronic trip unit with ground fault protection (LIG), which may require different setup and coordination compared to a standard thermal-magnetic HLD69600.
Is an external neutral sensor required for the ground fault function?
If installing this 3-pole breaker in a 3-phase, 4-wire system, an external neutral current transformer (sensor) is required to properly monitor neutral current and ensure accurate ground fault protection. In a 3-phase, 3-wire system, the external sensor is not needed.
Can this breaker be DIN rail mounted?
No. The SHLD69600G is a bolt-on molded case circuit breaker designed for direct bus connection in compatible Sentron panelboards and switchboards. It is not compatible with DIN rail mounting.
