Siemens Building Technology 141-0530 Thermostat
The Siemens Building Technology 141-0530 is a heavy-duty high limit manual reset thermostat designed for critical "lock-out" safety applications in commercial HVACR systems. Built for professional duct or surface mounting, this line voltage mechanical thermostat provides an essential safety layer by interrupting the circuit when temperatures exceed the setpoint. It features a broad operating temperature range from 25 to 215 degrees Fahrenheit (-4 to 102 Celsius), making it ideal for return air monitoring, fan coil changeover, or as a smoke/fire safety shutdown device in ventilation shafts. The SPST switch action is rated for high-amperage applications, supporting up to 16 Amps at 120 VAC or 8 Amps at 240 VAC. Engineered with a durable liquid-filled rigid bulb sensing unit and a rugged steel housing, this limit control thermostat ensures reliable performance in demanding environments where local codes require manual intervention after a high-temperature event occurs. Its 20-degree fixed switching differential and adjustable temperature stop provide precise calibration for specific system protection requirements.
Key Benefits- Enhanced Safety: The manual reset feature ensures that equipment remains locked out until a technician inspects the system after a high-temperature trip.
- Industrial Durability: Features a robust steel gray enamel cover and a liquid-filled, rigid bulb sensing unit built to withstand vibration and harsh duct environments.
- Flexible Compatibility: Works across 120V and 240V systems with high inductive load ratings for direct motor or fan control.
- Code Compliance: Meets standard fire safety and HVACR building codes for high-temperature limit "lock-out" protection in air handling units.
What is the difference between SPST and SPDT in these controls?
The 141-0530 is an SPST (Single Pole, Single Throw) device designed to open on temperature rise. While some Siemens variants use SPDT for changeover, this specific model is primarily used as a safety break to shut down fans or burners when the limit is breached.
Can the 141-0530 be used for surface mounting on pipes?
Yes, besides duct mounting, the rigid bulb and housing design allow for surface mounting on pipes, making it a versatile high limit control for hydronic or warm air applications where a manual reset is required.
How do I reset the thermostat after it trips?
Once the temperature has cooled below the setpoint (minus the switching differential), the manual reset button located on the face of the unit must be physically depressed to re-close the contacts and restore power to the circuit.
