Siemens SCMD69800ANGT 800A 3-Pole 600V LSIG Circuit Breaker
Siemens SCMD69800ANGT 800A 3-Pole 600V LSIG Circuit Breaker
Product Details
The Siemens SCMD69800ANGT is an 800-amp, three-pole molded-case circuit breaker from the Siemens Sentron series. It is designed for heavy-duty commercial and industrial electrical-distribution applications requiring electronic overcurrent protection and a high interrupting capacity.
The SCMD69800ANGT features a digital solid-state LSIG trip unit, providing long-time, short-time, instantaneous, and ground-fault protection. It is rated for operation at up to 600 Vac and provides an interrupting capacity of 65 kAIC at 480 Vac.
This breaker uses a bolt-on mounting configuration and is commonly used in compatible Siemens switchboards, distribution equipment, industrial enclosures, and replacement applications.
The standard breaker configuration is supplied without line and load lugs unless terminals are specifically shown in the product photographs or stated in the selected product condition.

What Does LSIG Mean?
The Siemens SCMD69800ANGT provides four electronic protection functions:
L — Long Time
Provides overload protection when current remains above the selected long-time pickup setting.
S — Short Time
Provides adjustable short-time protection and can support selective coordination between upstream and downstream protective devices.
I — Instantaneous
Trips the breaker rapidly during high-level short-circuit conditions.
G — Ground Fault
Provides ground-fault protection when the breaker and electrical system are correctly configured.
All trip settings must be selected by a qualified electrical professional based on conductor sizes, available fault current, equipment ratings, and the project coordination study.
Typical Applications
The Siemens SCMD69800ANGT may be suitable for properly engineered and compatible:
- Siemens switchboards
- Industrial distribution systems
- Main distribution sections
- Feeder breaker sections
- Commercial electrical equipment
- Manufacturing facilities
- Custom breaker enclosures
- Replacement and retrofit projects
- High-capacity industrial feeders
- Three-phase power-distribution systems
Compatibility must be confirmed before ordering. Matching the amperage and voltage alone does not guarantee that the breaker will fit the existing equipment.
Compatibility Information Required
For compatibility review, provide Ampstate with:
- Existing breaker catalog number
- Complete switchboard nameplate
- Photographs of the installed breaker
- Front and rear breaker photographs
- Bus connection arrangement
- Mounting hardware configuration
- Required line and load lugs
- Required trip settings
- Required control accessories
- Available fault-current rating
- Equipment voltage and system configuration
Terminals and Accessories
The standard Siemens SCMD69800ANGT breaker is generally supplied without terminals. Before ordering, confirm whether the installation requires:
- Line-side lugs
- Load-side lugs
- Bus connection hardware
- Mounting hardware
- Auxiliary switches
- Shunt trip
- Undervoltage release
- Bell alarm contacts
- Ground-fault sensing components
- Neutral current transformer
- Handle or operating mechanism
Only accessories specifically stated in the product listing or visible in the individual product photographs are included.
Product Condition
New Surplus
An unused genuine Siemens breaker obtained from surplus inventory. Original packaging, manufacturing date, labels, and cosmetic condition may vary.
Reconditioned
A previously installed breaker that has been inspected, cleaned, mechanically operated, and electrically tested according to Ampstate’s applicable inspection process.
Actual product photographs should be used whenever possible because terminals, accessories, trip settings, labels, and cosmetic condition may vary between individual breakers.
Important Ordering Notice
Before ordering, confirm:
- Catalog number SCMD69800ANGT
- 800A rating

- 600V system compatibility
- Required 65kAIC rating at 480V
- Bolt-on mounting arrangement
- Required LSIG trip functions
- Required terminals and lugs
- Equipment bus configuration
- Breaker dimensions
- Required accessories
Do not install this breaker based only on a visual match. The application must be reviewed by a qualified electrical professional.
