CATALOG Y GENERAL INFORMATION, FEATURES AND SELECTION FACTORS

GENERAL INFORMATION MDI Relays are all designed and built to meet the most exacting to prevent moisture damage and voltage breakdown through the pro- demands of the industry. They have won their high place in the electri- tective coating. cal field by doing the tough and tricky jobs that ordinary equipment The coils are wound on compact nylon bobbins and molded on to the could at best do in an uncertain manner. They have proven their ability metal tube to provide minimum power loss. This allows for low coil to stand up to the most adverse conditions of temperature, dust and power required to actuate the contactor. This also enables the units moisture, in all types of applications. All the care required for the to handle high loads with minimum derating due to higher ambient manufacture of high-grade instruments is used in the manufacture of temperatures. the switches. All switch parts are specially cleaned, and contamination Internal gasses prevent excessive arcing between the mercury and is avoided by use of tweezers, gloves, etc., when making assemblies. the electrodes which enables the unit to function for millions of cycles Contactors are hermetically sealed with high quality glass to metal with very low contact resistance, and minimum deterioration of the seals. internal parts. The stainless steel tube is totally encapsulated in high grade epoxy Available in all standard coil voltages, in single, two, three and four pole arrangements. Other coil voltages available upon request.

ACCEPTS 6 TO 14 AWG seconds on normally open units, and 4 seconds on normally LINE closed units. The timing limitation depends on the contact action LOAD required. A time delay function is accomplished in this unit by 3 sizing a hole in the time disc that will control the rate of the 1 4" .205" DIA. (2 HOLES) mercury 6ow. This controls the time it will take from the instant 9 3 16" the coil is powered until the mercury pools make contact with each other, closing the circuit between the load terminals. Typical 5 1 8" contact ratings 10 AMP @ 120 VAC. Pilot duty rating 720 VA. Common coil voltages are available. Standard load terminals are compression type.

Proper Fusing is Required MERCURY CONTACTORS 1. While MDI Mercury contactors handle high SOLID STATE inrush, such as lamps, mercury contactors SINGLE PHASE Single pole relay application are susceptible to damage by short circuit SUPPLY Line-Neutral, Line-Line currents, and should be fused to minimize

FUSE L1 short circuit fault currents. UL class RK-1 L 2 /N and class J fuses and semiconductor I²t SINGLE POLE LINE fuses more effectively protect relays. These RELAY are low current-peak fuses designed to limit short circuit currents. Regardless, when CONTROL there is a short circuit, relay operations VOLTAGE should be closely monitored afterward NEUTRAL because of the possibility of concealed LOAD damage that could cause the relays to behave inconsistently. -RECOMMENDED- 2 single pole relays in 3-phase application 250 VOLT 600 VOLT Delta and star connection (economy switch) KTN-R KTS-R SINGLE PHASE L1 L2 JJN/A3T JJS SUPPLY L 3 JKS/A4J FUSE KTK-R 2.
