Product description

The AC/DC sensitive residual current monitoring module RCMB42...EC is used for residual current monitoring of AC charging stations for electric vehicles in which DC or AC residual currents can occur whose magnitude can be permanently greater than zero.


Main features:

6mA DC sensor, type A RCD sufficient

All-current sensitive measurement of the residual current

Residual current monitoring with external residual current transformer

Integrated fault memory (adjustable)


Features:

DC sensor with additional AC triggering (type B characteristic)

Response value 2 - AC/DC 30 mA: RMS value measurement

Response value 1: DC 6 mA

Frequency range residual current 0...2000 Hz

Frequency range load current 45...65 Hz

Connection monitoring of the measuring current transformer

Fully shielded residual current transformer to prevent interference from external interference

Connection via spring terminals

Variants: Single-channel and dual-channel residual current measurement

Factory setting RMS 30mA, DC 6mA, non-adjustable, explicit use for charging stations.


Technical features:

Version with plug-in terminals

Special firmware suitable for Swiss applications

Classification according to IEC 60364-7-722 - Type B
