Siemens Combustion THERMAL-75X75 Barrier 320819-301 Extended End Connections: The 1/2"

Extended End Connections: The 1/2" ODF copper tails allow for fast brazing into the line without damaging internal components

Does this handle line voltage

This split-core model provides the same N/O switching logic as older solid-core units but simplifies the physical installation by snapping directly over the conductor

The 61625 is primarily designed for MARS 780 and 910 3-pole contactors

This 50A 2-pole circuit breaker serves as a direct OEM replacement to ensure the safety and operational integrity of your heating and cooling equipment

Siemens Combustion THERMAL-75X75 Barrier 320819-301 Extended End Connections: The 1/2"The Siemens Combustion THERMAL 75X75 is a professional grade thermal barrier engineered to protect Siemens QRA flame detectors from high ambient temperatures in industrial burner systems. Rated for continuous operation in environments up to 250F (121C), this 75x75 configuration acts as a critical thermal insulator between the heat source and the UV flame scanner housing. By mitigating thermal stress on sensitive internal components like the UV cell,
