  2. High-voltage interface relay - Wikipedia

    en.wikipedia.org/wiki/High-voltage_interface_relay

    High voltage interface relays, a.k.a., interface relays: [1] [2] or coupling relays or insulating interfaces [3] [4] is a special class of electrical relays designed to provide informational and electrical compatibility between functional components isolated from each other and not allowing for a direct connection due to a high difference of potentials.

  3. RoHS - Wikipedia

    en.wikipedia.org/wiki/RoHS

    Chinese RoHS labels, a lower case "e" within a circle with arrows, can also imply compliance. The WEEE directive logo. RoHS 2 attempts to address this issue by requiring the aforementioned CE mark whose use is policed by the Trading Standards enforcement agency. [32] It states that the only permitted indication of RoHS compliance is the CE mark ...

  4. Protective relay - Wikipedia

    en.wikipedia.org/wiki/Protective_relay

    The DTOC relay has been used extensively in the United Kingdom but its inherent issue of operating slower for faults closer to the source led to the development of the IDMT relay. [1]: pp 30-31 A definite time over-current (DTOC) relay is a relay that operates after a definite period of time once the current exceeds the pickup value. Hence ...

  5. Reed relay - Wikipedia

    en.wikipedia.org/wiki/Reed_relay

    (from top) Single-pole reed switch, four-pole reed switch and single-pole reed relay. Scale in centimeters. A reed relay [i] is a type of relay that uses an electromagnet to control one or more reed switches. The contacts are of magnetic material and the electromagnet acts directly on them without requiring an armature to move them.

    China RoHS (Restriction of Hazardous Substances), officially known as Administrative Measure on the Control of Pollution Caused by Electronic Information Products, [1] is a Chinese government regulation to control certain materials, including lead.

  8. Buchholz relay - Wikipedia

    en.wikipedia.org/wiki/Buchholz_relay

    Depending on the model, the relay has multiple methods to detect a failing transformer. On a slow accumulation of gas, due perhaps to slight overload, gas produced by decomposition of insulating oil accumulates in the top of the relay and forces the oil level down. A float switch in the relay is used to initiate an alarm signal. Depending on ...

  9. Contactor - Wikipedia

    en.wikipedia.org/wiki/Contactor

    AC contactor for pump application. A contactor is an electrically controlled switch used for switching an electrical power circuit. [1] A contactor is typically controlled by a circuit which has a much lower power level than the switched circuit, such as a 24-volt coil electromagnet controlling a 230-volt motor switch.
