                        This Harmony ZB, single contact block for low power switching contacts and dusty environment uses screw-clamp terminals. It is compatible with Harmony XB4 and XB5 control and signaling units. This contact block, uses for low power switching contact, allows fast and easy replacement and configuration of specific control and signaling products. It is easily installed and replaced on XB4 and XB5 control and signalling units and connects to control circuits with simple screw-clamp connections. It is applicable to be used in dusty environment and helps protect operators from unexpected contact with live circuits thanks to its IP69K protection index. 1 million cycle high endurance under 6A load allows less maintenance and damage in your installation. It has clear color scheme for NO and NC contact block types. Its wide range of operating temperatures from -40°C to 70°C allows versatility in usage of product.
