MCB Thermal Trip Verification / Demonstration Briefcase (As per IEC 60898)

Thermal trip test of low voltage single or multi pole MCBs

100 A model covers the three most popular MCB ratings: 6 A, 10 A, 16 A. Ideal for sales engineers for live demonstration
Quick test mode to test as per 2.55*In: Trip time and Test current get adjusted automatically on selection of MCB rating
Enclosed in briefcase for easy carrying (with a handle) and safety
Small in weight, size and portable than most of the conventional trip verification / demonstration units
SMPS current source ensures fine line and load regulation
Can test 1, 2, 3, 4 pole MCBs on a single DIN rail mount: Instant mounting and dislodging
Single micro controller unit for user interface with keypad: Current and trip and hold time is programmed digitally without the use of variable / auto transformer
Desired current is achieved quickly without time delay irrespective of mains fluctuations
1.13*In, 1.45*In, 2.55*In test in a single portable unit
4 models for the vast range of MCB current ratings: 10 A, 20 A, 100 A and 200 A max dc: User can selectively buy the model most suitable for the rating of MCBs to be produced / promoted

Introduction:

SCR Elektroniks presents you a briefcase enclosed test set up for thermal trip of low voltage single or multi pole MCBs that is lighter, more compact and portable than ever before. For example, the 100 A test set up weighs about a mere 7 kilos, making it ideal for sales engineers willing to demonstrate their MCB trip characteristics to their dealers and customers. In addition, the briefcase unit is suitable for MCB testing floors and its portability and light weight is an added asset for flexibility of location anywhere on the test floor.

The briefcase is designed mainly to perform 2.55*In test as per Table 7 (test c) of IEC 60898. In addition, test a and test b of Table 7, popularly known as the 1.13*In (no trip) and1.45*In (trip) test, is included to be demonstrated in dc current mode for the respective currents. Also the no trip time, trip time and total test time can be pre programmed on the interface module thus making the operation fully automatic. The all in one thermal trip demonstration unit makes it an ideal instrument for demonstration as well as verification.

The user friendly micro controller based interface module along with a smartly designed electronic DC source of up to 200 A makes it a state of an art product for precision testing and demonstration of low voltage MCBs.
