MSW Switch-Disconnectors32
On-Load Operation
The MSW switch-disconnectors were developed according to IEC 60947-3 and enable the manual drive
of motors, machines and other equipment under load. The design of the MSW switch-disconnectors
provides complete physical insulation between the circuit and the power supply when in the OFF
position. In this position, it is possible to use three padlocks in order to prevent inadvertent actuation,
increasing the safety of operators and maintenance personnel.
The switch-disconnectors can be used as disconnecting devices, according to the requirements of IEC
60204-1, and as general emergency switches.
