It integrates Type 2<br \/>\nand Type 3 protection classes, providing coordinated surge suppression for<br \/>\nequipment sensitive to transient overvoltages from switching operations or lightning.The SPD uses MOV-based modules with pluggable cartridges for easy maintenance.<br \/>\nIntegrated thermal disconnectors with visible fault indicators ensure safe operation,<br \/>\nwhile optional RC contacts allow remote fault monitoring and integration with building<br \/>\nmanagement systems or control circuits.<\/section>\n<section
