False triggering – Causes
Depending on stray capacitances and imbalances, leakage currents above 30mA may occur
during operation. Undesirable false triggering occurs under the following conditions:
§ When connecting installations to the supply voltage. This false triggering can be rectified by
using short-time delayed (super-resistant), selective (delayed switch-off) RCDs or RCDs
with increased trigger current (e.g. 300 or 500mA).
§ Due to higher frequency leakage currents for long motor cables under normal operating
conditions. This false triggering can be rectified for example using low-capacitance cables or
an output choke.
§ Due to imbalances in the supply grid. This false triggering can be rectified, e.g. using an
isolating transformer.
Information
Check whether the use of residual current protective devices with increased trigger current as
well as with short-time delayed or delayed switch-off trigger characteristics are permitted in your
application.
DANGER!
Electrical voltage! Risk of fatal injury due to electric shock!
Leakage and residual currents with a DC current component can restrict the functionality of type
A and AC residual current protective devices.
▪ Always follow the installation instructions for the protective devices you are using.
