Square High Voltage Zinc Metal Oxide Varistor 34S 680VAC 895VDC 1100V 40KA Insulate Epoxy Resin For SPD Surge Protection

Square High Voltage Zinc Metal Oxide Varistor 34S 680VAC 895VDC 1100V 40KA Blue Insulated Epoxy Resin For SPD Surge Protection

AMPFORT Thermally protected varistor stand for new development in circuit protection. It is made of metal oxide varistor and thermal links, thermal links can work when overheating caused by abnormal overvoltage.Compared with traditional design MOV+Thermal fuse in circuit, TMOV design simplifying end product aseembly by reducing the expense and rework associated with hand soldering operations because it support wave solderable.

1.34S metal oxide varistor (MOV), with epoxy resin

2. Diameter and thickness is controlell effectively within the design scale. 3.Peak current is reached the world leading level. It can afford 8/20us impulse, peak current Imax 40kA punch 2 times.

4.Thermal stability. Soldering thermal cutoff member with 145 degree, the cutoff time is no less than 5 senconds under 1A current; the cutoff time is 3-5 seconds under 1.5A current.

5.Energy absorption capacity, applied 2ms impulse, impulse current is 600A, the max. energy absorption capacity is more than 1000J.

6.Life time. Applied 83% varistor voltage at 85 degree to accelerate aging. The lifetime characteristic curve is good, varistor voltage change rate is less than +/-10%

7.power frequency withstand. Applied 1.2 tims electric load rate, tested for 5 minutes, the varistor is good, the varistor voltage change rate is less than +/-10%. 8.Stability. To exposure in the air for one week, varistor voltage and leakage current is less than |+/- 10%, product performance stable.
