Brief description of SENTRON VL

Thanks to their compact design, the SENTRON VL160 to VL1600 circuit breakers meet the
high requirements of today's electrical distribution systems. They are available both with
thermo-magnetic overcurrent trip units (16 A to 630 A), and with solid-state overcurrent trip
units (63 A to 1600 A). Depending on the desired level of diversity of the data, the
SENTRON VL can be connected to PROFIBUS DP via the COM20 module or via
SIMOCODE-DP, depending on the ETU used.
General information
The basic circuit breaker is designed for fixed mounting and can be easily changed to a plug-
in version or a withdrawable version using the appropriate kit. The available 3-pole and 4-
pole SENTRON VL circuit breakers are especially suitable for applications in the area of
plant, motor or generator protection, in starter combinations or as non-automatic air circuit
breakers.
