In summary – why Circuit Breakers?
While conventional fuses may be less expensive to install, their disadvantages can be particularly apparent especially in an automotive environment. The degree of electrical protection they provide is often inadequate for modern electrical systems and their potential for abuse is a serious problem for many vehicle operators. By comparison, circuit breakers of the correct type and rating offer significant benefits for the protection of vehicle wiring. • They are not subject to nuisance operation through transients or high rush-in currents such as lamp loads. Their rating can therefore be closely matched to the cable, guaranteeing optimum protection. • They will discriminate between motor start and prolonged stall conditions; motor windings can therefore be successfully protected. • They are not liable to premature failure through corrosion, fatigue, shock or vibration, or other external ageing influences. • There is no need to carry replacements. The risk of using unsuitable temporary f
