ZX1 series resistor is suitable for AC 50Hz voltage up to 500V and 440V DC voltage circuit, mainly used as motor starting, braking and speed of use. Resistor is open, it should be installed in the interior, and make masking to prevent electric shock. ZX1 series resistor from cast iron grating cast into meandering shaped element, ends with a gate-shaped earrings for installation purposes. Two models of its components made of large components ZT2 ZT1 small components. ZX1-1 series resistors and ZX1-2 series resistor installed the same size, so the two can be mutually stacked rack assembly, after stacking the sake of diminished its capacity in the resistor is not more than three can be directly stacked into, 4-6 frame, we must use a special steel structures to support the shelf, such as when more than 6 in each frame consisting of the groups should be maintained between the vertical plane of the interval of 380 mm or more. Scope altitude not exceeding 2,500 meters. Ambient temperature does not exceed +40 ℃ and no less than -30 ℃; +20 ℃ ± 5 ℃ when the air relative humidity less than 85%; surrounding medium does not enough to corrode metal and damage the insulation and potentially explosive gas and electric dust; shall be protected against rain and snow equipment and areas will be filled with water vapor; in the absence of severe vibration or strong Britain lame areas; Model significance overall and mounting dimensions main technical parameters Model at +20 ℃ Resistance (Europe) allows the load current (A) Heating Time Constant (s) cast iron resistive element model for each level the total number 1 2 3 4 5 ZX1-1/5 0.10 0.03 0.02 0.02 0.03 215 850 ZT1-5 20 ZX1-1/7 0.14 0.042 0.028 0.028 0.042 181 820 ZT1-7 20 ZX1-1/10 0.20 0.06 0.04 0.04 0.06 152 635 ZT1-10 20 ZX1-1/14 0.28 0.034 0.056 0.056 0.084 128 555 ZT1-14 20 ZX1-1/20 0.40 0.12 0.08 0.08 0.12 107 575 ZT1 -20 20 ZX1-1/28 0.56 0.168 0.112 0.112 0.168 91 432 ZT1-28 20 ZX1-1/40 0.80 0.24 0.16 0.16 0.24 76 540 ZT1-40 20 ZX1-1/55 1.10 0.33 0.22 0.22 0.33 64 408 ZT1-55 20 ZX1-1/80 1.60 0.48 0.32 0.32 0.48 54 490 ZT1-80 20 ZX1-1/110 2.2 0.66 0.44 0.44 0.66 46 445 ZT1-110 20 ZX1-2/38 1.52 0.456 0.304 0.304 0.228 0.228 55 660 ZT2-38 40 ZX1-2/54 2.16 0.648 0.432 0.432 0.324 0.324 46 585 ZT2-54 40 ZX1-2/75 3.0 0.9 0.6 0.6 0.45 0.45 39 535 ZT2-75 40 ZX1-2/105 4.2 1.26 0.84 0.84 0.63 0.63 33 400 ZT2-105 40 ZX1-2/140 5.6 1.68 1.12 1.12 0.84 0.84 29 450 ZT2-140 40 ZX1-2/200 8.0 2.4 1.6 1.6 1.2 1.2 24 382 ZT2-200 40 ZX1-2/280 11.2 3.36 2.24 2.24 1.68 1.68 20 ZT2-280 40
