The SCR Elektroniks RCCB Temperature Rise and Power Loss Test Bench is economically designed to verify temperature rise and measure power loss as per clause 9.8.1 of IEC 61008.
Stand-alone unit after initial configuration of test parameters.
28 Days test module can be included as per customer demand.
Cooling shall be provided by means of optimally placed Exhaust fans distributed all over to remove the hot air generated inside the panel cabinet.
Easy Serviceability due to smart internal wiring pattern.
Servo controlled mechanism to control current (+/- 1%) against incoming fluctuations.
Microcontroller based timer unit for quick and easy user interface and automated operation.
User may opt for test bench with heating chamber for testing at 60°C

The CT range and resistance for RCCB rating to be selected through shorting links: 16A, 20A, 25A, 32A, 40A, 45A, 50A, 63A at 30V with bypass arrangement for each phase.
Panel will be capable for testing three samples of same rating may SP/DP/TP/FP.
True RMS sensing current controller shall maintain current better than class 1.0 accuracy through out the range.
Digital Temperature Indicator min 28 Channels with minimum 28 No. Thermocouple bid, Teflon insulated will be provided with sufficient length to connect it to product. Channel selection by rotary switch.
Cooling will be provided by means of Exhaust fans distributed all over to remove the hot air generated inside the panel cabinet.
Overall accuracy of the panel is better than class 1.0
The entire system will be housed in sturdy M.S. Cabinet (trolley).
The equipment will have very good finish preferably powder coated Siemens Grey color finish..
Calibration certificate will be provided for individual meter and also for complete system.
Following meter indications will be provided: a) Digital Temperature Indicator with 28 input for thermocouple. b) Digital Volt Meter with 5 ranges (200mV, 2V, 20V, 200V, 250V) – 1 No To measure open circuit voltage & mV drop across rccb . c) Digital Ammeter with CT (Indication on servo controller) – 3 Nos.
Adjustable Constant Current Source 3 Nos.
The test bench can be customized as per the rated current range of the RCBOs (typically upto 63 A and upto 125 A). Additionally, The bench can be made to test MCBs also. The number of temperature measurement channels can be customized as per the client preference. Further customizing options are micro-controller based / PC based with fully automatic seection and testing plus report generation. The equipment can be clubbed with 28 days testing equipment.
The test, similar to that of an MCB, is carried out to measure the power loss across each pole, i.e. what are the losses per pole in an MCB. Also temperature rise of various parts - including current carrying parts can be measured. Thus, the reasons for power loss can be assessed.
