UL-compliant line fuse
Use the following fuses for UL-compliant operation:
•
Fuses of class RK1, for example Bussmann KTS-R-xxA/600 V.
•
For drive controllers sizes and 1 you can also use fuses of class CC.
•
For drive controllers size 0 to 2 you can also use type E motor starters from
Eaton Industries, consisting of a motor protection switch and supply
terminal.
See the table below for suitable fuses:
4.6.2
Residual current safety device
STOBER devices can be protected with a Residual Current protective Devices
(RCD) to detect residual currents. Residual current protective devices prevent
electrical accidents, especially ground fault through the body. They are
generally distinguished according to their triggering limit and suitability for
detecting different types of residual current.
Depending on the function, stray currents may occur when operating drive
controllers. Stray currents are interpreted as residual currents by residual
current protective devices and may therefore lead to false triggering.
Depending on the relevant power supply connections, residual currents may
occur with or without a DC current component. Because of this, you should
take into consideration both the height and also the shape of the possible stray
or residual current when selecting a suitable RCD.
DANGER!
Electric shock hazard!
The combination of single-phase drive controllers and residual current
protective devices type A or AC can lead to false triggering of the RCDs.
Stray currents with a DC current component may occur in 3-phase drive
controllers.
Always protect single-phase drive controllers with
residual current
protective devices type B, sensitive to all currents
, or with type F, sensitive
to mixed currents.
Always protect 3-phase drive controllers with
residual current protective
devices type B, sensitive to all currents
.
