MRP-201
- Description
Specialist in residual current circuit breakers
The Sonel MRP-201 residual current circuit breaker meter is a specialist device for measuring all types of residual current circuit breakers - direct, short-delay, selective; types AC, A and B. It allows to measure tripping current, tripping time depending on differential current, resistance of protective conductor and contact voltage. Measurements can be performed individually or in series in automatic modes (all preset measurements for a given waveform or for all waveforms); simultaneous measurement of current and tripping time is also possible (with one RCD trip).
Features
- Testing RCD breakers of AC, A, B types
- Testing of general, short delay and selective RCDs for the rated current values 10, 15, 30, 100, 300, 500 mA
- Measurement of IA trip current and tripping time tA for currents 0.5 IΔn, 1 IΔn, 2 IΔn, 5 IΔn
- RE and UB measurement without RCD tripping
- Extended AUTO function of RCD measurement
- Measurement of IA and tA during one RCD tripping
Additional functions
- Checking the correctness of PE connection using a contact electrode
- Measurement of voltage (0 … 500 V) and network frequency
- Memory of 990 results
- Wireless data transmission to a computer
- Backlit keypad
Application areas
The meter enables the user to measure the parameters of residual-current devices (RCDs), such as time or operating current. The device is useful for testing electrical systems with circuits protected by RCDs of AC, A and B type.
Increased resistance to environmental conditions
The meter will cope well in difficult environmental conditions. Protection against penetration of dust and water is ensured by a unique housing with a level of protection IP67.
Communication and software
You can easily transfer measurement data to your computer via wireless communication. In order to generate a report on measurements for electric shock protection, use Sonel Reports PLUS software. Saving the downloaded data to the simplest formats and printing is provided by free Sonel Reader software.
