Safety meets competence

Testing system for commercial kitchens up to 600 A

Complete electrical testing of large kitchens for commercial applications. A safety and function test is necessary for the most 3-phase DUT following production.

Industry: electrical industry


The existing test stations will be modernised in the first place. Besides the improvement of processes, it also includes the complete documentation of the test data. Moreover, our customer preferred a single connection of the DUT. Following this, all tests should occur automatically. The large currents up to 600 A require the use of suitable switching elements, plug connectors and cables.


A PC-controlled testing system was developed for the safety test according to IEC / EN 60335. The function tests consist essentially of current and power measurements.

Attention had to be paid to the high leakage currents of up to several 100 A in both the safety tests and the function tests. These leakage currents cannot be avoided in heaters with a high output. The workplace is designed in accordance with EN 50191 and thus, protects the testing personnel. The whole test equipment, including the PC are housed in a cabinet with the dimensions 3 x 19'' / 42 HU in a space-saving manner. The transmitter and the switching elements for connection of the individual tests are also here.
