1. Introducció
This manual provides essential information for the safe and effective installation, operation, and maintenance of your ProPart Pepi 140F Thermal Breaker. Please read this manual thoroughly before use and retain it for future reference.
The Pepi 140F Thermal Breaker is an automatic resettable fuse designed to open (turn on) an electrical circuit when the ambient temperature reaches 140°F (60°C) and remain closed until the temperature drops below this threshold. It is a Normally Open (NO) switch, meaning it is off until the temperature rises to the specified point.
2. Informació de seguretat
WARNING: Risk of Electric Shock and Fire.
- Always disconnect power before installing, servicing, or removing the thermal breaker.
- Installation should be performed by a qualified electrician or knowledgeable individual familiar with electrical systems.
- Ensure the thermal breaker's voltage and current ratings are compatible with your application. The contact rating is 5A / 120V.
- No supereu les capacitats elèctriques especificades.
- Do not modify the thermal breaker or its wiring.
- Keep the device away from water and excessive moisture unless specifically rated for such environments.

3. Producte acabatview i Característiques

Image 1: Two Pepi CR thermal breakers. Each unit consists of a small, rectangular metallic body labeled "PEPI CR" with two insulated wire leads extending from one end. The wires are dark gray and appear to be stranded copper. The overall appearance is compact and designed for integration into electrical circuits.
The ProPart Pepi 140F Thermal Breaker is a compact and reliable temperature-activated switch. Its key features include:
- Automatic Resettable: The switch automatically resets (reopens) once the temperature drops below the activation threshold.
- Normalment obert (NO): The circuit is open (off) until the temperature reaches 140°F (60°C), at which point it closes (turns on).
- Disseny compacte: The body measures approximately 20mm x 5mm x 6mm, excluding the wire leads, allowing for integration into various applications.
- Cables de cable: Equipped with flexible wire leads for easy connection.
- Valoració de contacte: Valorat per 5 Amperes at 120 Volts (5A / 120V).
4. Configuració i instal·lació
Seguiu aquests passos per a una instal·lació correcta:
- Desconnexió d'alimentació: Before beginning any installation, ensure that the power supply to the circuit where the thermal breaker will be installed is completely disconnected. Verify with a voltage provador.
- Selecció d'ubicació: Choose a location where the thermal breaker can accurately sense the temperature you wish to monitor. The device should be placed in direct proximity to the heat source or area requiring temperature control.
- Muntatge: The thermal breaker is designed for panel mounting. Secure the body of the switch in a stable position using appropriate mounting hardware (not included) or by integrating it into an enclosure. Ensure the metallic body has good thermal contact with the environment it is monitoring.
- Cablejat: Connect the wire leads of the thermal breaker into your circuit. As a Normally Open (NO) switch, it will complete the circuit (turn on) when the temperature reaches 140°F (60°C). Ensure all connections are secure and properly insulated to prevent short circuits. The wire leads are designed for through-hole terminal connections.
- Verificació: Once installed, double-check all connections and ensure no bare wires are exposed.
- Reconnexió d'alimentació: Carefully restore power to the circuit.
5. Funcionament
The ProPart Pepi 140F Thermal Breaker operates automatically based on ambient temperature:
- Normal State (Below 140°F / 60°C): When the surrounding temperature is below 140°F (60°C), the switch remains in its Normally Open (NO) state, meaning the circuit connected through it is open (off).
- Activation State (At or Above 140°F / 60°C): As the ambient temperature rises and reaches 140°F (60°C), the thermal breaker will automatically close the circuit (turn on).
- Reset State (Temperature Drops): The switch will remain closed as long as the temperature is at or above 140°F (60°C). Once the temperature drops below 140°F (60°C), the thermal breaker will automatically reset to its Normally Open (off) state.
This automatic operation makes it suitable for applications requiring temperature-activated control or safety cutoffs.
6. Manteniment
The ProPart Pepi 140F Thermal Breaker is designed for maintenance-free operation. However, periodic inspection is recommended:
- Inspecció visual: Periodically inspect the thermal breaker and its wiring for any signs of physical damage, corrosion, or loose connections.
- Control ambiental: Ensure the operating environment remains within the specified temperature and humidity ranges. Keep the area around the breaker clean and free of debris that could impede proper temperature sensing.
- Neteja: If necessary, gently clean the exterior of the thermal breaker with a dry, soft cloth. Do not use abrasive cleaners or solvents.
If any damage is observed or if the device is not functioning as expected, disconnect power and replace the unit.
7. Solució De Problemes
