Usage examples
  • Madalpinge-võimsuslüliteid nimetatakse tavaliselt kaitselüliteiks ja neil võivad olla liigvoolu-, lekkevoolu-, pingevähenemis- jm vabastid.

circuit-breaker preferred
Usage examples
  • 14.1. Electrical equipment according to Directive 94/55/EC 14.1.1. Protection against overheating of conductors: 14.1.2. Type of circuit breaker: 14.1.3. Type and operation of battery master switch: 14.1.4. Description and location of safety barrier for tachograph: ...
  • All generators and circuits must be protected against excess current in any unearthed pole or conductor. Automatic circuit-breakers with short-circuit and surge trips, or safety fuses of the sealed type, may be used for this purpose. Such electrical protection devices must be so installed as to be adequately protected against jolting.

  • mõõtevahend, mis võimaldab mõõta kaitselüliti/jaotusseadme parameetreid
  • instrument that measures the parameters of circuit breaker/switchgear
kaitselüliti tester preferred
Usage examples
  • Kaitselüliti tester on lülitusseade, mis katkestab rikkevoolud, ja elektrikaare kustutamine, hetkel, mil kaitselüliti kontaktid lahutatakse (ahel katkestatakse), nõuab hoolikat projekteerimist.
switchgear tester preferred
Usage examples
  • A switchgear tester is a switching device that interrupts fault currents; the extinguishing of the electric arc at the moment the circuit breaker contacts are separated (the circuit is broken) requires careful design.
