Siemens 3VL1710-1DA33-0AA0 Electrical Circuit Breaker

Siemens 3VL1710-1DA33-0AA0 is a 3‑pole VL160X molded‑case circuit breaker engineered for 415 V AC distribution with a nominal current rating of 100 A. It employs an electronic trip unit (ETU) with a TM/ETU configuration for precise overcurrent protection and line protection, rated In = Ir = 100 A. The device provides a standard high‑fault interruption capacity of up to 55 kA at 415 V AC, making it suitable for medium‑sized feeders in industrial power distribution and motor circuits. This 3VL1 variant is part of Siemens SENTRON’s VL160X family, designed for system protection in electrical networks and generator protection schemes, and is offered in a non‑automatic (no auxiliary release) version as indicated by the 0AA0 suffix. Typical applications include distribution panels, starter configurations, and other 3‑phase installations where reliable protection of conductors, transformers, and downstream loads is required. In practice, engineers select this 100 A VL160X 3P breaker to guard against overloads and short circuits while maintaining compatibility with Siemens’ standard mounting and accessory ecosystem for compact, modular switchgear.
