SPD/Arresters（Representative Standard：CSA）
SPDs and arrestors (lightning arrestors) are surge protection devices that prevent electrical and electronic equipment failures that can occur due to lightning. If lightning causes a transient overvoltage (surge) to enter the equipment, the electronic circuit will fail. SPDs and arrestors (lightning arrestors) work to protect precision equipment, etc. by controlling transient applied voltages that occur momentarily. The SPD and arrestor (lightning arrester) work to bypassed and escape the surge to the earth. Zinc oxide elements are mainly used to absorb lightning surges, and in addition, silicon elements, molybdenum elements, gas tube elements, etc. are combined to make the products. The type varies depending on the application, such as for equipment, for power supplies with fuses, for power distribution board, for signal lines, etc. In addition, there are various features such as types with excellent responsiveness and durability, non-continuous types, compact types, etc.

OTOWA
A compact type with a built-in detachment device and deterioration indicator
[Features]
· Includes a built-in detachment device. Includes a deterioration indicator.
· The built-in detachment mechanism prevents the SPD from smoking and/or igniting in cases where the ZnO element deteriorates.
· With function for indicating detachment mechanism operation.
· Compact, enables space-saving.
· Combined type between wires and ground protecting from lightning-induced surges.
· Use of multi‐terminal components helped in making the smallest product in the industry. Same dimensions are available for 200V to 500V.
· Safe lightning surge bearing strength.
· Using maximum discharge current 5kA (8 / 20 μs), it is difficult to break even with a large lightning surge.
· A long service life type that stands up to repeated lightning surges of 1000A500 times.From: ฿ 1,769.61 Days to Ship:
