Siemens SENTRON 3WL10 - Applications, Portfolio, and Basic Properties

3WL10 air circuit breaker
The 3WL10 air circuit breaker is a current-carrying circuit breaker with IEC certi󹪝cation (3WL1)
and is an addition to the existing 3WL1 IEC portfolio. It has the following characteristics:
• Frame size 0 (FS 0) with a rated current I
n
of 630A to 1250A
• Optionally available either as a 󹪝xed-mounted version or as a withdrawable version
• An especially high I
cw
value (up to 50kA 1s) and I
cu
value (up to 66 kA @440 V)
3VA27 molded case circuit breaker
The 3VA27 molded case circuit breaker is a current-limiting circuit breaker with IEC certi󹪝cation
and is an addition to the existing 3VAIECportfolio. It has the following characteristics:
• Frame size 1600A with a rated current I
n
of 800A to 1600A
• Choice of two designs:
– as a handle operating mechanism, e.g. as an additional manual operating mechanism
– as a stored energy mechanism for integration of internal spring charging motors (external
dimensions are not a󹪜ected by this)
• Optionally available either as a 󹪝xed-mounted version or as a withdrawable version
• An especially high I
cu
value (up to 110kA @415V) and I
cw
value (20kA 1s)
