19、EN 3841-507:2004 (E) 4 1 Scope This standard specifies a method of verifying the ability of circuit breakers to withstand mechanical shocks. It shall be used together with EN 3841-100. 2 Normative references The following referenced documents are indispensable for the application of this document. F
20、or dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

21、thods Part 100: General 3 Method 3.1 Mounting The circuit breakers shall be mounted on the shock table according to 4.2 and 4.3 of EN 3841-100. The means of mounting shall be designed so as to transmit the pulses without absorption or natural resonance. The electrical connection shall be made with t
22、he cables of the sections specified in EN 3841-100, Table 1. The connection cables shall be attached to the shock table approximately 100 mm from the terminals. The circuit breakers and the cables shall be mounted with the torque indicated in the product standard. 3.2 Procedure The circuit breakers
23、shall be subjected to the mechanical shocks test according to ISO 7137, test procedure 2.1. Three shocks shall be applied in each direction and for every switch setting: in the closed position at 90 % of current rating; in the open position. The acceleration peak value (half sine-wave from of 11 ms
24、duration) is specified in the technical specification. During the test, it shall be established that the contacts do not close for a period 10 s (circuit breakers in the open position) or open for a period 10 s (circuit breakers in the closed position). 4 Requirement Requirements in accordance with
25、technical specification and product standard.
