When browsing any electrical store online, you'll likely find dozens of products labeled “surge protector.”For consumers outside the electrical industry, it's often difficult to distinguish between these similar-looking protective devices. Today, we'll guide you on how to properly identify lightning arresters.

Recently, we have frequently received feedback from customers that counterfeit products have been found in the YRO products they purchased, involving multiple items such as circuit breakers, combiner boxes, and surge protectors.

Isolation switches are critical safety components in any electrical system, including the demanding environments of new energy applications like solar PV arrays, energy storage systems (ESS), and EV charging infrastructure. Their primary function is to provide a visible break and ensure safe isolation for maintenance. However, like any electromechanical device, they are susceptible to faults that can compromise system safety and uptime. Based on industry data and common field reports, here are several frequent problems encountered with PV Isolation switches and their implications for your operations.

Modern power systems are threatened by transient voltage surges. These short, high amplitude voltage pulses, usually lasting from nanoseconds to milliseconds, caused by lightning strikes, grid fluctuations or the switching of industrial equipment, can silently destroy precision electronic devices ranging from laptops to photovoltaic inverters. Although circuit breakers are crucial for preventing overloads and short circuits, they are powerless against microsecond-level surges that bypass their mechanical tripping mechanisms. This article will delve into the functions that lightning arresters can perform but circuit breakers cannot, as well as why both are indispensable in electrical protection.

From March 5 to 7, 2025, at Booth B09 of IMPACT Exhibition Center in Bangkok, YRO will bring its core products, such as solar power shutdown equipment and low voltage components, to the “ASEAN Energy Storage & Smart Energy Expo”.

It is a common phenomenon to encounter the tripping of the main power circuit breaker during thunderstorms, or when using high-power equipment. However, many users have such a question: Can installing lightning arrester effectively reduce or even prevent such tripping accidents? Anyone who has a basic understanding of surge protectors and circuit breakers knows that, although surge protectors are electrical protection devices, their functions are different from those of circuit breakers. It doesn't matter if you don't understand. This article will take you to deeply understand the role of surge protectors in practical use, and explore whether they can really prevent the main circuit breaker from tripping unexpectedly.
