Mercury Displacement Relays are all designed and built to meet the most exacting demands of industry. Mercury Relays have won their high place in the electrical field by doing the tough and tricky jobs that ordinary equipment could at best do in an uncertain manner. Mercury contactors have proved their ability to stand up under the most adverse conditions of temperature, dust and moisture, in all types of applications.

The MDI 60-AMP normally open contactors are designed and manufactured to high quality specifications and the contactors are commonly used in various heating, lighting, and many other industrial applications including high voltage ultraviolet type loads. The contacts are encased in hermetically sealed stainless steel tubes to provide reliable switching for millions of operations. MDI has manufactured this contactor/relay since 1975. It is available in the single, two, three & four pole models.  MDI contactors/relays also come in normally closed versions and Motor rated styles.

To be called a GFCI (Ground Fault Circuit Interruptor) the unit needs to trip no higher than 6mA.  Above that the unit becomes an ELCI (Equipment Leakage Circuit Interruptor).

A Ground-fault occurs when there is a break in the low resistance grounding path from a tool or electrical system. The electrical current may then take an alternative path to the ground through the user, resulting in serious injury or death.  The ground-fault circuit interrupter, or GFCI, is a fas acting circuit breaker designed to shut of electric power in the event of a ground fault within as little as 1/40 of a second. It works by comparing the amount of current going to and returning from the equipment along the circuit conductors. When the amount going differs from the amour retuning by approximately 5 milliamperes (4-6mA), the GFCI trips/interrupts the current.

The GFCI is rated to trip quickly enough to prevent an electrical incident.  If it is properly installed and maintained, this will happen as soon as the faulty tool is plugged in.  If the grounding conductor is not intact or of low impedance the GFCI may not trip until a person provides a path.  In this case, the person will receive a shock, but the GFCI should trip so quickly that the shock will not be harmful. The most common type of shock is from the Ground Fault. GFCIs also protect against fires, overheating and wire destruction.

Una pérdida a tierra ocurre cuando hay una ruptura en el camino de resistencia baja para conexión a tierra de una herramienta o un sistema eléctrico. La corriente eléctrica entonces puede tomar una trayectoria alterna a la tierra a través del trabajador, resultando en lesiones serias o la muerte.

El interruptor para circuitos con pérdida a tierra, o GFCI, es un circuito interruptor de energía de acción rápida diseñado para desconectar la energía eléctrica en caso de una pérdida a tierra en un lapso de 1⁄40 de segundo. Esto funciona comparando la cantidad de corriente que sale y que regresa del equipo a lo largo de los conductores de circuito. Cuando la cantidad que sale es diferente de la cantidad que regresa por aproximadamente 5 mili-amperios, el GFCI interrumpe la corriente.

El GFCI está clasificado para desconectar la corriente suficientemente rápido para prevenir un incidente eléctrico. Si es instalado y mantenido correctamente, esto pasará tan pronto como el equipo defectuoso es enchufado. Si el conductor de conexión a tierra no está intacto o es de baja impedancia, el GFCI quizás no funcione hasta que una persona le proporcione una trayectoria. En este caso, la persona recibirá una descarga, pero el GFCI debe activarse tan rápidamente que la descarga no sería mortal o dañina.
