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. In addition, the user can configure some other test settings with respect to the on time, off time as well as the number of test cycles.

The pneumatic test fixture is designed in such a way that the user can test MCBs of similar designs but having dimensions to a different degree. Thus, the test bench is ideal for test labs where MCBs of different brands (and hence different dimensions) can be tested. In addition, if the user is a MCB / RCCB / RCBO manufacturer, the fixture can be customized to hold more that one kind of circuit breaker.

Another feature of this bench is that only mechanical endurance can be carried out by the test bench in a stand alone fashion by automically disconnecting the electrical load bank and configuring the test cycles on the micro controller timer unit .
