8.1 Specifications/regulations/approvals
The 3RW3 semiconductor motor control units, referred to below more suc-
cinctly as soft starters, meet the UL and CSA requirements.
Table 8-1: Standards, certificates, and approvals, 3RW3
Normal switching duty
The 3RW3 soft starters can be used for normal switching duty in acc. with
DIN VDE 0100 Part 460:
A switch for normal switching duty must be provided for all circuits that are
to be switched independently of other parts. Switches for normal switching
duty do not
necessarily all switch active conductors
of a circuit.
Isolation
The soft starters do not meet the requirements for isolation
in acc. with DIN VDE 0100 Part 460 and EN 60 947-1:
Every circuit must be capable of being isolated from the active conductors
of the power supply.
Circuit groups can be isolated by a common device if this is permitted by the
operating conditions. In the open position, devices with an isolating function
must have a corresponding isolating distance and an indicator showing the
positions of the moving contacts.
