Cur- rents below this range are covered by special contacts for micro current. The minimum current for ordinary contacts of our 2 Amp./5 Amp. series is also 50 mA. For currents below 50 mA, Crossbar contacts, called K contacts, are applied. Since the current range covered by cross contacts is 1~100 mA, 50~100 mA is covered both by ordinary contacts and micro capacity contacts. As this range is a recommended standard, ordinary contacts can be used for 20 mA as well, however, the possibility of contact failure will increase. Though the rating is indicated as 1~100 mA for crossbar contacts, these contacts may also be used in any amperage out of this range. 1~100 mA is the range that 100% conduction is ensured. The structure of crossbar contacts is that of two noble metal contacts in trapezoidal shape, contacting with each other crosswise. The benefi t of this structure is that there will be smaller possibility for contact failure because it can assure the large contact pressure per unit area. Contact type indication Model designation method Contacts which open when the temperature rises are designated as X, and those which close when the temperature rises are designated as Y. Shown in the diagram is the temperature at which the contacts operate when the temperature rises (the high temperature side). CONTROL THERMOSTATS (MQT) X Xbar and Y Ybar are used for contacts that operate when the temperature falls (the low temperature side). X Xbar indicates the contact that closes when the temperature falls. Y Ybar indicates the contact that opens when the temperature falls. Z indicates transfer con- 2 AMP SERIES tacts. XZ is the main contact that opens when the temperature rises. XZ Xbar Z is the main contact that closes when the temperature falls. C is the standard rank designation for X contacts and B is standard for Y contacts. Please MQT8H K35XC represents a thermostat with crossbar contacts (K means crossbar contact). For 5 Amp.
