2 2 Definitions
Add the following definition:
2.2.101.2
non-bimetallic single operation device
single operation device having a temperature sensing element which is part of a combination action
control, the operation of which cannot be separated from other functions of the control and having a
non-bimetallic thermal element that operates only once and then requires complete or partial
replacement
NOTE 1 When such parts can be tested separately, they are considered to be thermal links within the scope of EN 60691.
NOTE 2 The ageing period and thermal response of the device is dependent on the intended use of the device. As a result,
the nature of the testing applicable to the device should be representative of the application conditions for which the protective
control is intended (see 7.2).
NOTE 3 Non-bimetallic single operation devices provide the equivalent of micro-disconnection.

sensing elements are conditioned for an ageing period equal to either 750 h or the result of the
specified number of cycles declared by the end product application divided by 4 (calculation value is
the number of hours), whichever is greater. The ageing temperature is declared in Table 7.2, Item 115,

period. Operation of the devices shall be detected as indicated in 15.5.3.107.
17.15.2.2 At the end of the ageing period, the samples are removed from the apparatus.
The appropriate tests of Clause 15 shall be repeated on six untested samples and the six samples
subjected to the conditioning of 17.15.2.1 and the temperatures measured shall be within the declared
deviation limits, with the electrical conditions of the test V and I .
