Siemens VL800L Circuit Breaker - 800A
Siemens VL800L Circuit Breaker 800A, 100kA.
The Siemens 3VL6780-3SE36-0AA0 is a VL800L molded case circuit breaker designed for high-capacity power distribution and protection. It features a very high breaking capacity (Icu) of 100kA at 415V AC across its three poles. The integrated electronic trip unit (ETU20) provides LSI (Long-time, Short-time, Instantaneous) protection with an adjustable rated current (In) from 320A to 800A. Overload protection settings range from 1.5 to 7 times the rated current (Ir), and short-circuit protection is set at 8 times the nominal current (In).
This circuit breaker is essential for protecting electrical systems in industrial facilities, power generation plants, and large commercial buildings. It ensures safety by interrupting fault currents, preventing damage to equipment and preventing electrical fires. It is suitable for main distribution boards and incoming feeders.
