China 4P AC MCCB Manufacturer, Supplier, Factory

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

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.

Dear old customers, thank you for your company all the way! If you have visited Markjapy Company and placed an order, during the exhibition from June 11th to 13th, you can get a free handheld small fan when you come to the site! Cool and refreshing with you, accompanying you to enjoy a relaxing exhibition tour ~

Against the backdrop of global PV installed capacity exceeding 2TW, safety has become a core pain point restricting the development of the industry. Leakage and fire risks of traditional PV systems have not been effectively solved for a long time, and the mandatory implementation of regulations such as NEC 2017 in the U.S. has made module level fast shutdown technology a new rigid need in the industry. 2025, Markjapy successfully passed UL3741 certification with its technological breakthrough.

Fast Shutdown refers to a safety feature implemented in solar power systems that allows for the rapid deactivation of the system in the event of an emergency or when maintenance is required. This feature is especially important for photovoltaic (PV) systems, where solar panels generate electricity even when disconnected from the grid. Fast Shutdown ensures that all high-voltage components are quickly de-energized to protect both first responders and maintenance personnel from electrical hazards.

Dear business partners: When wisteria flowers meet four leaf clovers, China is about to welcome the May Day International Workers' Day. According to the holiday arrangement of The General Office of the State Council of China, Markjapy will enter the holiday mode from May 1st to May 4th and resume normal work from April 26th to 27th.
