Differential switch up the
C5G
When a differential switch type B is requested (AC/DC sensitive according to
norm IEC 60755), use a model featuring a fault current value >= 300 mA and
adjustable triggering time > 100 ms.
No automatic circuit breakers (fault current = 30 mA) are allowed.
Powering cable
Depending on the Customer supply specifications an armored quadripole (three
phases plus earth) cable in compliance with norm IEC 60332-1 or CEI 20/35 is
requested to carry out the connection to the mains.
On Main Circuit breaker On X120 connector
Max cable size: 10 mm² / 8 AWG Max cable size
: 6 mm² / 10 AWG
Cable gland by cabinet
base
The M25 type cable gland supplied is suitable for a cable featuring an outside
diameter between 13 and 18 mm (between 0.5 and 0.71 in)
