Protection of electric contours

Various combinations of safety locks, fusible inserts and chain breakers are applied to protection of contact chains of an electric equipment of the car. Assembly blocks, are established in salon of the car and in an impellent compartment of a vehicle.

Safety locks

The general information

Each separate safety lock is used for protection of any concrete electric contour or at once several contours. The identification card of placing of safety locks in the assembly block is usually put on a cover of the last, from its external party.

In assembly blocks the safety locks of a compact design equipped with bayonet contact plugs, and, if necessary, easily taken by fingers from the nests in the block are located. At refusal any of electric power consumers first of all always it is necessary to check a condition of a corresponding safety lock. Turn a key in the ignition lock in position ON and by means of a lamp-sampler probe open plugs of each of safety locks. If the lamp lights up at connection to each of plugs, hence, a safety lock as it should be. If pressure takes place only from food giving, means, the safety lock has fused. We will notice also, that usually the safety lock case is made of transparent plastic through which it is easy to define a condition of a working crosspiece.

At replacement of the fused safety lock strictly watch that the established replaceable corresponded on type left of an element. Calculated on various nominal force of a current safety locks physically can differ nothing from each other, not being thus interchangeable. Each of electric chains has various working parametres and replacement of the safety lock calculated on certain force of a current requires various degree of protection, therefore, mismatching it on parametres is fraught with the most serious consequences (up to fire occurrence). Working parametres of a safety lock (nominal force of a current) are usually designated on its plastic case.

If the new safety lock after installation also fails at once, it is not meaningful to make its further replacement, - before it is necessary to reveal and eliminate the reason of occurrence of an overload in a chain. In most cases that appears the short circuit of connecting electroconducting caused by damage of its isolation.



1. Schemes of an arrangement of safety locks in assembly blocks are presented in Specifications to the present Chapter.
2. In an impellent compartment the assembly block settles down in immediate proximity from the storage battery, in salon - at the left under the panel of devices.

3. Remove a cover of the corresponding assembly block.

4. By visual survey reveal the failed safety lock and by means of a special clip take it from the landing nest.

5. Study a condition of contact plugs in a reception nest of the assembly block, remove oxidation traces, defective plugs replace.

6. Establish to the place of the failed safety lock replaceable, corresponding original on parametres.

The complete set of spare safety locks is usually stored in салонном the assembly block.

Fusible inserts

The general information and replacement


1. Fusible inserts are used for protection of chains in which for any reason usual safety locks cannot be used, such as a contour of system of ignition, and also for power chains in which circulates высокоамперный a current.
2. The main complete set of fusible inserts is mounted in an impellent compartment near to the storage battery. The second group is placed in the assembly block of safety locks/relays located in the neighbourhood.
3. At an exit of a fusible insert out of operation extremely to find out the reason of occurrence of an overload in a corresponding electric contour.
4. The failed fusible inserts of usual type are not subject to regenerative repair. Track, that the replaceable element completely corresponded on the rating data failed.

Chain breakers

The general information

Chain breakers are used for protection of such components of system of an onboard electric equipment, as head headlights and drive electromotors стеклоподъемников, activators of door-locks, etc.

On some models after operation breakers revert to the original state automatically. If caused switching-off of the breaker the overload had not incidental character, it is necessary to check up a condition of a corresponding contour immediately. After elimination of malfunction the chain breaker enters again into a normal mode of functioning. Sometimes return of the breaker to a working condition should be made manually after elimination of the reason of an overload.
