Residual-current circuit breakers
Labelling of RCCBs
Meaning
AC-sensitive residual-current circuit breaker (RCCB, type AC)
Pulse-current sensitive residual-current circuit breaker (RCCB, type A)
All-current sensitive residual-current circuit breaker (RCCB, type B)
Definition
In the following text “RCCB” is used for “residual-current circuit breaker”.
Protection of persons and animals
DIN VDE 0100 with residual-current operated protective devices (RCCB):
•
The controllers are equipped with a mains rectifier. If a short-circuit to frame occurs, a smooth DC residual current
can block the activation of the DC sensitive or pulse-current sensitive RCCBs and thus destroy the protective
function for all units connected. We therefore recommend:
– ”pulse-current sensitive RCCB” or ”all-current RCCB” in systems equipped with controllers with single-phase
mains connection (L1/N).
– ”all-current sensitive RCCB” in systems equipped with controllers with three-phase mains connection (L1/L2/L3).
Rated residual current
Please observe the rated residual current for the selection of the RCCB:
•
Controller with single-phase mains connection:
30 mA rated residual current
•
Controller with three-phase mains connection:
300 mA rated residual current
The RCCB can be activated unintentionally under the following conditions:
•
In the event of capacitive leakage currents between the cable screens (especially with wall mounting).
•
Simultaneous connection of several inverters to the mains
•
If RFI filters are used.
Installation
The RCCB must only be installed between the supplying mains and the controller.
Standards
(All-current sentitive RCCB)
All-current sensitive RCCBs are described in the European Standard EN EN 50178 and in the IEC 755.
The EN 50178 has been harmonized and has been effective since October 1997. It replaces the national standard
VDE 0160.
