Siemens WLCOM35 Profinet Modbus TCP Mounting Kit

Siemens WLCOM35KIT is a factory-sealed mounting kit that adds PROFINET IO and Modbus TCP networking directly to a 3WL air circuit breaker by housing the COM35 communication module. The kit includes the COM35 module and mounting hardware required to install the module beside the breaker, delivering a compact, field-installable solution for industrial Ethernet communications. The COM35 provides PROFINET IO connectivity and Modbus TCP capability, enabling data exchange with PLCs, HMIs, and SCADA systems over standard Ethernet networks, so you can monitor breaker status, read diagnostics, and issue remote control commands from your existing automation infrastructure. This upgrade is commonly used to retrofit legacy installations or to equip new installations that require integrated network access at the protection device level, simplifying wiring and improving visibility into protective equipment via common industrial protocols. The WLCOM35KIT is specifically marketed as a Modbus TCP / PROFINET module with mounting hardware, designed for Siemens 3WL series circuit breakers and compatible with standard Siemens protective devices in industrial environments.
