Utilizing true RMS sensing, this 500A Sentron LD frame breaker ensures precise circuit protection across commercial applications. The integrated Sensitrip IV electronic trip unit allows for highly configurable long-time and instantaneous (LI) adjustments. This bolt-on MCCB installs into Siemens Sentron panelboards and switchboards. It serves existing infrastructure and is replaced by the 3VA6450-6HL31-0AA0 using an adapter strap kit.
What does the "LI" stand for in the SHLD6B500LI part number?
The "LI" indicates that this breaker features an electronic trip unit with Long-Time (L) and Instantaneous (I) adjustable trip functions. This allows for precise tuning of the overload and short-circuit protection settings.
What types of enclosures or equipment are compatible with this breaker?
The SHLD6B500LI is designed for use in Siemens Sentron panelboards, switchboards, and motor control centers (MCCs) that accept LD Frame circuit breakers.
Does this breaker provide ground fault protection?
No. The SHLD6B500LI features an LI (Long-Time, Instantaneous) trip unit. It does not include the Ground Fault (G) function required for equipment ground fault protection. An LIG or LSIG trip unit would be required for that capability.
Can I adjust the trip settings on this circuit breaker?
Yes, the electronic trip unit on the SHLD6B500LI is fully adjustable for both Long-Time and Instantaneous trip functions, allowing you to coordinate it with other protective devices in your electrical system.
Is this breaker a direct replacement for older Siemens LD frame breakers?
Yes, the SHLD6B500LI shares the same physical dimensions and mounting footprint as other Siemens Sentron LD Frame breakers, making it a suitable replacement or upgrade for older thermal-magnetic or electronic LD frame units with matching specifications.
