The APS-TRX40 surge arrester’s core component is UL-certified high-performance MOV technology, which has a high surge discharge capacity and a low voltage protection level. It can effectively suppress transient overvoltages caused by lightning strikes and other electrical sources on power lines. The APS-TRX40 is intended for low-voltage transformer connections. The APS-TRX40 uses high-grade stainless steel with highly waterproof and flame-resistant packaging to protect against the risk of the harmful effects of transient surges. This results in smooth operation and reliability of a transformer, resulting in extended life of the asset. It is ideal for long-term exposure to harsh natural environments.
