Relay Module
■
Relay module
Input voltage: DC 24 V
Contact capacity: AC 250 V 10 A; DC 28 V 10 A
When the opening/closing load capacity of the control circuit breaker is large, it
needs to be converted by the relay module before control. There are two
installation modes: (1) 35 mm standard guide rail, (2) direct installation.
Position Door Interlock
■
Position door interlock
When the main body of the drawer mode circuit breaker is in the "Test" or
"Connection" position, the cabinet door is forbidden to open; and when the
circuit breaker body is in the "Disconnection" position, the cabinet door is
allowed to open.
RCD Residual Current
Transformer
■
RCD residual (leakage) current transformer
When the grounding protection is residual current type, a zero-sequence current
transformer which is suitable for the protection of small current needs to be
added. The signal sampling mode is the sum of phase current vectors.
■
ZT100 grounding transformer
When the grounding mode is the ground current return type (W), the installation dimensions of the additional
transformer are shown in the figure below.
■
External N-phase transformer (3P+N mode)
When the controller is 3P+N, the external neutral transformer has the external dimensions as shown in the figure
below.
