The test, similar to that of an MCB, is carried out to measure the power loss across each pole

MCB Temperature Rise and Power Loss Test Bench (IEC 60898 Clause No. 9.8)

Lab Test R&D

The SCR Elektroniks 3 station MCB Temperature Rise and Power Loss Test Bench is economically designed to verify temperature rise and measure power loss as per clause 9.8 of IEC 60898 with the circuit designed to follow test procedure as per Cl 9.8.2. The temperature rise is measured in accordance with Cl 9.8.3 and 9.8.4 while power loss is measured and verified as per Table 15 of Cl 9.8.5.

This test equipment also covers testing as per Indian Standard IS 8828 as well as Indonesian Standard SNI 8528-1 (BSN)

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.

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

Easy Serviceability due to smart internal wiring pattern

Servo controlled mechanism to control current (+/- 1%) against incoming fluctuations

50 / 60 Hz operation as per incoming line frequency

Overall accuracy of the panel is better than class 1.0

Digital Temperature Indicator with input from thermocouple

Digital Ammeter with CT (Indication on servo controller) 6. Class 1 Accuracy

Digital Volt Meter with 5 ranges (200mV, 2V, 20V, 200V, 250V) to measure open circuit voltage & mV drop across MCB

Class 1 Accuracy

The tester can be customized as per the desired range of currents and curves (B,C,D). In addition, where PC based testing is desired, the user may opt for online time vs temperature curves and data logging at a particular current rating. Also, this test can be clubbed in the 28 days test bench for improved economic feasibility.

The product is designed to test the power loss per pole of the breaker under test. Thus, it checks indirectly if the breaker consumes more units of energy than what the standard allows. Additionally, temperature probes (of temperature rise test) pinpoint those areas in the breaker that are actually responsible for active power loss, thus a key input is provided to the MCB designer.
