2 DC switch Recommended: a DC circuit breaker with a
rated voltage greater than or equal to 1000
V DC and a rated current of 20 A Prepared by the customer
3 AC switch Recommended: an AC circuit breaker with
a rated voltage greater than or equal to 250
V AC and a rated current of 25 A Prepared by the customer
4 Energy meter The energy meters that can connect to the
BRE-I-5K14K are CHINT-DDSU666,
CCS-WNC-3Y-400-MB,
Gavazzi-EM340DINAV23XS1X, and
Gavazzi-EM111DINAV81XS1X. Prepared by the customer
⚫
If the external AC switch can perform earth leakage protection, the rated leakage action
current should be greater than or equal to 100 mA.
⚫
The BRE-I-5K14K doesn't include an integrated residual current device (RCD). If an
external residual current device (RCD) is used, a device of type
A
should be used, with
a tripping current of 100 mA or higher.
⚫
If multiple BRE-I-5K14Ks connect to the general RCD through their respective external
AC switches, the rated leakage action current of the general RCD should be greater than
or equal to the number of BRE-I-5K14Ks multiplied by 100 mA.
⚫
A knife switch cannot be used as an AC switch.
