Features
- Permanent residual current monitoring in accordance with DGUV regulation 3
- 4 measuring channels are available for residual current measurement
- Choice of AC, pulse or universal current sensitive measurement by selecting the measuring current transformer for each channel (type A/F/B/B+ in accordance with IEC 60755 or VDE 0664-400)
- Continuous connection monitoring of the measuring current transformer
- Separate evaluation of the AC and DC components as well as the effective value of the AC and DC (RMS) residual current is possible
- Overcurrent (standard), undercurrent or window function can be selected for each channel
- Alternatively, each measuring channel can be configured as a digital input
- Response ranges: 10 mA...10 A (type B/B+), 6 mA...30 A (type A/F)
- Frequency range: DC...20 kHz
- Preset function
- Reload function
- Time delays are adjustable
- Adjustable frequency behavior
- Analysis of harmonics up to the 400th harmonic, calculation of the THD value
- One digital input, one digital input/output and one multifunctional digital/analog output
- Integrated combined test/reset button, connection for external buttons
- One device status LED, two alarm LEDs and one alarm LED per channel
- RS-485 interface with Modbus RTU (read out measured values/parameterization)
- Compatible in the system network with other Modbus RTU-capable device series from Bender, including the RCMB300 series, RCMS150-01 and RCMB13...-01
- Compatible with Bender gateways of type COM465IP, CP9...-I
- Up to 247 RCMS410s can be used on the bus - NFC interface for parameterization with the Bender Connect app
- Expansion/retrofitting or modification of functionalities in the event of changed monitoring requirements
- Complies with DIN EN IEC 62020-1
Suitable for
- Measurement and evaluation of residual, fault and rated currents of consumers and systems
- Monitoring residual currents in stationary electrical systems and equipment as an alternative to RIso testingin accordance with accident prevention regulation DGUV V3 and the German Ordinance on Industrial Safety and Health (BetrSichV)
- Detect gradual deterioration of insulation and support preventive maintenance
- Monitoring flammable currents in operating facilities at risk of fire
- EMC monitoring of TN-S systems for "stray" currents and additional N-PE bridges
- Monitoring PE and PA conductors for absence of current
- Monitoring of N conductors for overload due to harmonics
- Monitoring digital inputs
Easy to configure - via app
The Bender Connect app can be used to configure individual response values, Modbus addresses, time delays and relay functions. Configuration can already be carried out in a de-energized state before commissioning or even before installation. The serial and article number, device name and other information can be read via the Bender app and used for system documentation. Cloning is also very easy: for recurring configurations, a template created once can be uploaded to any number of devices.
