Schweizer Standardausführung gemäss
NIN Kap.5.3.2.3
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.
