Safety locks - the general information

1 — the Suitable safety lock
2 — Fused

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 burned-down safety lock is easy for distinguishing from serviceable by survey of its transparent plastic case. Attentively examine a safety lock about identification of its peregoraniye. If the safety lock outwardly looks normally, but suspicions on its malfunction remained, make conductivity check between the knife plugs acting from its case.

At replacement of safety locks watch compliance replaceable old on type. The safety locks calculated on a various current can outwardly look identical therefore it is necessary to give special attention to marking. Replacement of the burned-down safety lock on calculated on smaller - and especially big - a current is undesirable. Each electric contour needs different extent of protection. Watch that marking on the case of a safety lock corresponded to a 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 eliminate the reason of its knocking-out. In most cases that appears short circuit of electroconducting of the contour, caused by break or damage of isolation of a wire.
