The test system is a special version of the thermal + Magnetic test test system. The single power source able to deliver either thermal or magnetic test parameters set on the PC by the user.
Input 415 V, 30 A (max), 3 phase, 50 Hz
Covers the entire range of MCB from 0.5 A to 125 A : B, C, D curve.
Thermal Test : User can set up to 4 times the rated current of MCB which includes 1.13 times rated current, 1.45 times rated current and 2.55 times rated current.
Magnetic Test : 0.5 – 125 A MCB : B, C ,D curve Short time duty (about 100 mS) is 3000 A, which covers the max 2500 A (125 A MCB : 20 times rated current for D curve MCB). The Test is done at low voltage.
Transient Recording Meter reads the instantaneous current and Trip time.
Current Transformer ranges – 1A, 2A, 5A, 10A, 25A, 50A, 100A, 200A , 500A , 1000A, 2000A & 3000A – selected automatically by the software on basis of chosen MCB rating. Output Current : 1. Continuous rating between 1 A to 600 Amps 2. Short time up to 3000 Amps
Micro Controller based unit & software controls the sequence of operation and measures time with 1 msec resolution (for magnetic / instantaneous tripping). Heavy Duty Contactors for internal switching as per PC based test sequence.
Separate three TIME INTERVAL METERS for each station
Swamping inductors / resistors for stable current
The product can be customized as per the number of stations: 1 (stand alone), 2, 4, 6, 8, 10 and 12 stations. Additionally, the product can be microccontroller based with each microcontroller controlling an individual station, or a PC based wherein the PC controls all the stations simultaneosuly and independenly of each other. The product is available as a standalone module with micro controller based control – without the use of PC as a low cost alternative with features as scalability and accuracy intact.
This product is used by leading MCB manufacturers on their Lab & production floor.
