multict DACT residual current transformer, type A
The residual current transformers from the DACT series can be used in 3- and 4-wire AC networks. The typical residual currents in the AC range in a system can be recorded. They are evaluated by the module Multisio D2-4AI3DO residual current monitor.
Along with residual currents typical for the system, the residual current transformer also measures various capacitive leakages. These can be caused by line filters, for example. This phenomenon must be watched for when evaluating the measured residual current.
Application
Highly sensitive current sensor for capturing even the smallestresidual currents.
multict KBU…D split residual current transformer, type A
The residual current transformers from the KBU…D series can be used in 3- and 4-wire AC networks. This series has the advantage that the transformers can be installed without shutting off and disconnecting the lines.
The typical residual currents in the AC range in a system can be recorded. They are evaluated by the module Multisio D2-4AI3DO residual current monitor. Along with residual currents typical for the system, the residual current transformer also measures various capacitive leakages. These can be caused by line filters, for example. This phenomenon must be watched for when evaluating the measured residual current.
Application
For subsequent installation in electrical systems
multict RCMB 70 residual current transformer, type B/B+
The RCMB 70 residual current monitor can be used in 2-, 3-, and 4-wire networks. All residual currents in the AC and DC range of a system are recorded and evaluated. The following settings can be individually configured on the residual current monitor:
- Rated residual current limit 30, 100, 300, 500, and 1000 mA
- Frequency range 100 Hz, 2, 20 and 100 kHz
- Integration time short, medium or long
Application
- Residual current monitoring in the industry
- Status-based monitoring of insulation condition
- Replace/supplement insulation test (component of repeated test in accordance with DGUV Regulation 3)
Monitoring of
- DC power supply systems (UPS, PV, LED lights-)
- High-frequency loads (SMPS, motor drives-)
- Critical infrastructures (data centers, medicine-)
