Temperature limiter with head and connector SCHLOSSER RTL (model 603200012)

The SCHLOSSER RTL temperature limiter with adjustment head and connector is a compact safety device designed to monitor and limit system temperature in heating and cooling installations. It combines a sensing element, a manual adjustment head and an electrical connector to provide reliable over-temperature protection for boilers, water heaters and HVAC components. The unit is intended for installation in systems where a straightforward mechanical limiter is required to prevent excessive temperatures and protect equipment and users.

Advantages

The RTL limiter offers a simple mechanical solution for temperature protection that does not rely on complex electronics. Its integrated adjustment head allows straightforward setting of the trip point, while the supplied connector simplifies electrical integration. The compact design supports installation in confined spaces and the device is suitable for use in a variety of heating and cooling circuits. Materials and construction are selected to provide stable performance under normal operating conditions.

Suitable for

• Boiler temperature protection
• Water heater safety cutoff
• HVAC system over-temperature prevention
• Industrial or domestic heating circuits requiring a mechanical limiter

Key specifications

• Function: mechanical temperature limiter with manual adjustment
• Configuration: separate sensing element, adjustment head and electrical connector
• Mounting: suitable for inline installation in heating or cooling circuits (compact form factor)
• Operation: device interrupts circuit at set temperature to prevent overheating
• Materials: corrosion-resistant housing and connector contacts for typical HVAC environments

How to use

Mount the sensing element at the location representative of the medium temperature (for example on a boiler flow pipe or water heater outlet) and secure the adjustment head where it can be accessed for setting. Connect the electrical connector to the control circuit in accordance with local wiring standards and the system schematic. Set the desired trip temperature using the adjustment head, then test the limiter operation at known temperatures or during commissioning to ensure correct activation and reset behavior. Follow all applicable safety and installation regulations when working on pressurized or live systems.

Usage recommendations

Use the temperature limiter as part of a comprehensive safety strategy: combine with pressure and flow controls, schedule periodic functional checks, and replace the device if physical damage or corrosion is observed. Ensure electrical connections are tight and protected, and that the adjustment head remains accessible for inspection and maintenance.
