Overview
The Siemens SND6A100LIG is a 1000 A, three-pole Sentron SND6 molded-case circuit breaker for systems up to 600 V AC. Its digital solid-state trip unit provides LIG protection functions: long-time, instantaneous, and ground-fault.
Key Features
-
Safety: Electronic LIG trip functions provide adjustable overload, instantaneous short-circuit, and ground-fault protection.
-
Installation: Fixed bolt-on construction is intended for qualified installation in compatible Siemens distribution equipment; application-specific conductor lugs are selected separately.
-
Compatibility: Use only where the equipment documentation identifies the exact SND6A100LIG catalog number and Sentron SND6 frame.
-
Performance: Interrupting ratings are 65 kA at 240 V AC, 50 kA at 480 V AC, and 25 kA at 600 V AC.
