Although Surge Protective Devices (SPDs) play a vital role in protecting high-value electrical and electronic equipment and ensuring uninterrupted operations in industrial facilities, SPDs themselves have a limited lifespan. Often installed inside electrical panelssometimes in remote or inaccessible areastheir status cannot be monitored immediately. This makes regular inspection and maintenance essential and unavoidable.
To address this, Kumwell has developed a comprehensive solution for efficient SPD status monitoring. The system supports automation and remote control, enabling online real-time monitoring of SPD functionality. This significantly reduces risks and enhances confidence in protecting critical equipment at all times.
Surge Protection Class II for
AC Power System (KB12 Series)
The KB12 1PN Series is a Surge Protective Device (SPD) that combines Metal Oxide Varistor (MOV) and Gas Discharge Tube (GDT) technology to protect against transient overvoltage. It is classified as a Class II SPD according to IEC 61643-11. This model is designed for use in Lightning Protection Zone 2 (LPZ 2) and is intended to be installed at the boundary between LPZ 1 and LPZ 2, in compliance with IEC 62305. Its primary function is to perform equipotential bonding, discharge surge current to ground, and suppress overvoltages caused by switching operations in the buildings power distribution system.
The KB12 1PN is ideal for surge protection at distribution boards (DB) or load panels (LP) in industrial facilities, residential buildings, and commercial offices.
Surge Protection Class I+II Spark Gap
for AC Power Systems (KBG50 Series)
The KBG50 1P Series is a Surge Protective Device (SPD) utilizing Triggered Spark Gap (TSG) technology, designed to protect against transient overvoltages. It is classified as a Class I+II SPD in accordance with IEC 61643-11. This model is specifically engineered for use in Lightning Protection Zone 1 (LPZ 1) and should be installed at the boundary between LPZ 0 and LPZ 1, or in zones exposed to direct lightning strikes, as defined by IEC 62305. It is ideal for areas with high lightning risk and serves as a critical first line of defense in surge protection systems.
The KBG50 1P is ideal for installation at main electrical panels in buildings or industrial facilities requiring high-level protection. It is designed to guard against direct lightning-induced surges and overvoltages caused by electrical load switching.
Surge Protection Class I+II
for DC Power Systems
The KLSA-12R5-U48V is a Surge Protective Device (SPD) based on Metal Oxide Varistor (MOV) technology, designed to protect against transient overvoltages in DC power systems. It is classified as a Class I+II SPD according to IEC 61643-11. This model is engineered for installation in Lightning Protection Zone 1 (LPZ 1), specifically at the boundary between LPZ 0 and LPZ 1, as well as in higher exposure zones, as defined by IEC 62305.
The KBG50 1P is ideal for installation at main electrical panels in buildings or industrial facilities requiring high-level protection. It is designed to guard against direct lightning-induced surges and overvoltages caused by electrical load switching.
Surge Protection Class II
for DC Power Systems
The KZ12.DC20K Series is a Surge Protective Device (SPD) utilizing Metal Oxide Varistor (MOV) technology, designed to protect against transient overvoltages in DC power systems. It is classified as a Class II SPD in accordance with IEC 61643-11. This model is specifically designed for use in Lightning Protection Zone 2 (LPZ 2) and should be installed at the boundary between LPZ 1 and LPZ 2, as defined by IEC 62305.
The KZ12.DC20K Series is ideal for surge protection in DC power supply systems, such as solar power systems, backup battery systems, or DC equipment within industrial facilities. It helps prevent damage from overvoltage and enhances the safety of loads, devices, and control circuits.
