Safety locks

Protection of electric contours of the car is provided with application of a combination of safety locks, breakers of a chain and fusible inserts. It is easy to distinguish the burned-down safety lock from its transparent plastic case, serviceable by survey. Attentively examine a safety lock regarding identification of its burn-out. If the safety lock externally looks normally, but suspicions on its malfunction remained, make check of conductivity between the knife plugs acting from its case.

Burn-out of safety locks of this kind can be revealed by visual survey

When replacing safety locks you watch compliance replaceable old on type. The safety locks calculated on various current can externally look identical therefore special attention should be paid to marking. Replacement of the burned-down safety lock on calculated on smaller – and especially big – current is undesirable. Each electric contour needs different degree of protection. You watch that marking on the case of a safety lock corresponded to the current on which the corresponding contour is calculated.

If the replaced safety lock immediately fuses, it is not reasonable to continue its replacement. Before it is necessary to reveal and remove the cause of its knocking-out. In most cases that appears the short circuit of an electrical wiring of a contour caused by break or damage of isolation of a wire.
