MCB Endurance Test Bench

(IEC 60898-1 Clause 9.11)

The SCR Elektroniks Endurance Test Bench is designed for electrical and mechanical endurance MCB and RCCB as per clause 9.11 of IEC 60898-1. The source and the load is designed to comply as per the general test conditions specified in Cl 9.11.1. The accompanying pneumatic fixture is designed to hold custom built designs of MCB and RCCB while the microcontroller based timer unit can be configure to follow test procedure summarized in Cl 9.11.2.

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

  • Completely stand alone unit after initial configuration of test parameters
  • Smartly designed pneumatic fixture to accommodate more type of MCBs
  • Safety / Diagnostic Feature: Contact Weld / Contact Open indication for opening or welding of current carrying contacts inside the panel
  • Micro controller based operation enables input settings as per IEC as well as user configurable for other settings.
  • Graded inductors for accurate power factor output Industrial grade wire wound resistors enables continuous operation without overheating of the load bank
  • The user may simultaneously test MCBs of different brands and compare the tst results (Ideal Application for Test Labs and Certification Agencies).
  • User friendly digital interface to input test parameters
  • MCB Range Selection: Through neatly labelled shorting links
  • Input 380 / 415 440 V, 50 / 60 Hz (User Specified), 3 phase, 100 A continuous
  • Load Current: 0.5 A to 100 A
  • Electro Magnetic Counter: To count the number of operations
  • Pneumatic Pressure required: 6 Bar
  • Metering:
    i) Micro-Controller based Programmable Timer
    ii) 3 phase digital ammeter
    iii) 3 phase digital voltmeter
    iv) 3 phase digital power factor meter
  • Ratings of MCB covered: 0.5, 1, 1.6,2, 3, 4, 6, 8, 10, 13, 16, 20, 25, 32, 40, 45, 50, 63A, 80A, 100A, 125 A selectable with Shorting Links

The bench can be customised in to 0.5- 63, 6- 63, 0.5 – 32, 0.5 – 125 A current range. Further, the user may choose if he wants a micro-controller based control or a PC / PLC based control. The fixture is designed as per the MCB samples provided. (A similar equipment is offered to test RCCBs and RCBOs for endurance testing that differs in load parameters and fixture design, please refer the relevant section if you are interested).

The test bench tests mechanical and electrical endurance characteristics of MCB for quality assessment purposes.
