Siemens 3VA5 UL Frame 400 Molded Case Switch - 400A, Self-Protected
Siemens 3VA5 UL Frame 400 molded case switch - 400A, self-protected.
The Siemens 3VA5340-0BB31-0AA0 is a 3-pole molded case switch from the 3VA5 UL Frame 400 series, designed for circuit isolation and protection. It has a maximum short circuit current rating of 65kA at 480V. This model features line protection with the MCS110 self-protection unit, a nominal current (In) of 400A, and a fixed short-circuit protection (Ii) set at 15 times the nominal current, without connection.
This molded case switch is ideal for applications where a high-current isolating switch with integrated short-circuit protection is required. It is commonly used as a main switch for electrical installations, industrial machinery, and distribution boards where direct on-line connection is not needed or where upstream protection is provided.
