The circuit breaker has been designed to operate problem free with a minimum of maintenance. To guarantee this a few simple maintenance and cleaning operations are required. When exercising with care the described maintenance operations, any problem will usually be discovered and corrected before they lead to a standstill.

Technical maintenance of the circuit breaker must be carried out after 10,000 operating cycles. The number of operations can be read from the operation counter (E). This involves the adjustment of the compression and the stroke length of the contacts. For this purpose, contact Deba nv or call in the help of trained and authorised service personnel.
