RCMB422CHEC-2 Single-channel residual current monitoring device

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 and functions

- 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.
