Safety locks - the general information

Protection of electric contours of the car is provided with application of a combination of safety locks, breakers of a chain and fusible inserts. The assembly block of safety locks is located under a cover from below the panel of devices in the left part of a control panel. Besides there is a block of the relay and the safety locks, located in an impellent compartment and named also capacity centre value of distribution (the Relay Section - the general information see).

The assembly block of safety locks is located at the left under the panel of devices and closed by a cover.

Each of safety locks is intended for protection of the contour which names are put on a payment of the assembly block.

In the assembly block safety locks of tiny type are used. Such contact safety locks with ножевыми plugs are easily inserted and taken by fingers. In default components of an electric contour always first of all check a condition its safety locks. The burnt down safety lock is easy for distinguishing from serviceable by survey of its transparent plastic case. Attentively examine a safety lock about its revealing перегорания. If the safety lock outwardly looks normally, but suspicions on its malfunction have remained, make conductivity check between ножевыми plugs, their acting its cases.

Перегорание safety locks of this kind can be revealed by visual survey.

At replacement of safety locks watch conformity replaceable old on type. The safety locks calculated on a various current strength can outwardly look identical, therefore it is necessary to give special attention to marks. Replacement of the burnt down safety lock on calculated on smaller - and especially big - a current strength is undesirable. Each electric contour requires different degree of protection. Watch that marks on the safety lock case corresponded to the current strength stipulated by Specifications on which the corresponding contour is calculated.

If the replaced safety lock immediately fuses, it is not reasonable to replace it again. Before it is necessary to reveal and eliminate its reason выбивания. In most cases that appears short circuit of electroconducting of the contour, caused by breakage or damage of isolation of a wire.
