Arteche RJ-4XR4 trip relay Arteche Trip and lockout relays

Arteche RJ-4XR4 trip relay : Intended for tripping applications where high quality requirements in operating time (with models even tripping in less than 3 ms.) and breaking capacity are needed, that is the case of tripping HV and MV circuit breakers.

Arteches’ master trip relays (ANSI-94) are specially designed to exceed the requirements of all kind of protection and control circuits, like those than operates circuit breakers, contactors and other primary switching equipment in power plants, substations or power distribution systems at heavy industries.

With a high breaking capacity, low and high burden options, models from 2 to 16 changeover contacts (DPDT, 4PDT, 8PDT, 16PDT with form-C contact configuration), different mounting alternatives and a wide range options (like self, hand or electrical reset, flags, test button), Arteche trip relays are ideally suited for Direct Transfer Trip (DTT) and other trip schemas guarantee performance, reliability and low consumption during a long life cycle.

Arteche manufactures trip and lockout relays with a wide range of options to met each application requirements. Reliability an performance by default for safety-critical and most demanding applications in power system environments like HV breaker operation or control and command circuits in high voltage substations / bulk generation power plants / HV power system control.

With a fast operation time (between 3 and 20 ms. depending on the model), high breaking capacity and a wide range of auxiliary voltages, Arteche trip an lockout relays can be manufactured with a high burden configuration, complying with ESI 48-4 international standard, as EB2 class relays, to avoid unwanted trip operations due to pickup or transients, particularly if the relay operating coil is connected to long wiring.

With more than 60 years’ experience manufacturing high quality electromechanical relays (EM relays), ARTECHE is a worldwide reference for critical and safety applications. Our offering includes a complete range of auxiliary, trip, lockout and contactor relays specially designed for the most demanding environments. Millions of Arteche power relays are in service worldwide.

Arteche plug in power relays are designed to provide high breaking capacity, high dielectric strength (galvanic isolation), high speed operating time and are able to withstand vibrations and seismic conditions. With a wide range of voltages, options and accessories, Arteche relays perfect fit each application requirement, guaranteeing a reliable performance during a long product lifecycle, also under severe environmental conditions.
