3. Instruccions de seguretat
- Always disconnect power at the main service panel before installing or servicing the circuit breaker.
- Utilitzeu l'equip de protecció individual (EPI) adequat, com ara guants aïllants i ulleres de seguretat.
- Ensure all wiring connections are tight and secure to prevent overheating and fire hazards.
- Do not use the circuit breaker if it appears damaged.
- Consult a qualified electrician if you are unsure about any part of the installation or operation.
- Adhere to all local and national electrical codes (e.g., NEC in the USA).
4. Instal·lació (Configuració)
4.1 Eines necessàries:
- Screwdriver (appropriate size for terminals)
- Pelacables
- Voltage provador
- Equips de protecció individual (EPI)
4.2 Passos d'instal·lació:
- Desconnexió d'alimentació: Locate the main service panel and turn off the main circuit breaker to completely de-energize the electrical system. Verify with a voltage tester that power is off.
- Muntatge: The S202-C16 is designed for wall mounting. Securely attach the circuit breaker to a suitable mounting surface within an appropriate enclosure, following manufacturer guidelines for panelboard or enclosure installation.
- Cablejat:
- Connect the incoming line wires to the designated line terminals (typically at the top).
- Connect the outgoing load wires to the designated load terminals (typically at the bottom).
- Ensure proper wire gauge is used for the 16 Amp rating and 110 Volt system.
- Tighten all terminal screws to the specified torque settings (refer to device markings if available, otherwise consult general electrical standards).
- Verificació: Double-check all connections for tightness and correct polarity. Ensure no bare wires are exposed.
- Tancament del recinte: Close the panelboard or enclosure cover securely.
- Restauració d'energia: Torneu a encendre l'interruptor principal.
5. Funcionament
The ABB S202-C16 Miniature Circuit Breaker features two toggle switches, one for each pole, to control the flow of electricity.
- Posició ON: Push the toggle switch(es) fully upwards to the 'ON' position to allow current to flow through the circuit.
- Posició OFF: Push the toggle switch(es) fully downwards to the 'OFF' position to interrupt current flow and de-energize the circuit.
- Posició DISPARADA: If an overcurrent (overload or short circuit) occurs, the circuit breaker will automatically trip. The toggle switch(es) will move to an intermediate or 'TRIPPED' position (often center or slightly below center). To reset a tripped breaker, first move the switch(es) fully to the 'OFF' position, then push it/them fully to the 'ON' position.
Note: If the circuit breaker repeatedly trips, do not attempt to force it on. This indicates a persistent fault in the circuit that must be investigated and resolved by a qualified electrician.
6. Manteniment
L'interruptor miniatura ABB S202-C16 està dissenyat per a un manteniment mínim. Tanmateix, es recomana una inspecció periòdica per garantir un rendiment i una seguretat òptims.
- Inspecció visual (anual): With power disconnected, visually inspect the circuit breaker for any signs of physical damage, discoloration, loose connections, or corrosion.
- Neteja: If necessary, gently clean the exterior of the circuit breaker with a dry, lint-free cloth. Do not use liquid cleaners or solvents.
- Estanquitat del terminal: Periodically check the tightness of terminal connections, especially after initial installation and during routine electrical system checks. Ensure power is off before checking terminals.
Do not attempt to open or repair the circuit breaker. There are no user-serviceable parts inside. If the device is damaged or malfunctioning, it must be replaced by a qualified professional.
