5. Návod k obsluze

The BR120ST circuit breaker operates automatically to protect circuits from overloads and short circuits. It also features a shunt trip for remote operation.

5.1 Normální provoz

• Pozice ON: When the handle is in the "ON" position, power is supplied to the circuit.
• Poloha OFF: Moving the handle to the "OFF" position manually disconnects power to the circuit.
• Zapnutá poloha: If an overload or short circuit occurs, the breaker will automatically trip, moving the handle to an intermediate position (often between ON and OFF, or fully OFF depending on the design).

5.2 Resetting a Tripped Breaker

If the breaker trips, follow these steps:

1. Identifikujte příčinu: Determine and correct the cause of the overload or short circuit (e.g., unplug overloaded appliances).
2. Úplně VYPNUTO: Move the breaker handle firmly to the full "OFF" position. You may feel a click.
3. Reset to ON: Pevně ​​zatlačte rukojeť do polohy „ON“.
4. If the breaker immediately trips again, do not attempt to reset it. There is a persistent fault that requires professional attention.

5.3 Shunt Trip Function

The shunt trip mechanism allows the circuit breaker to be tripped remotely by an external electrical signal. This is typically used in emergency shutdown systems or control applications.

• When the shunt trip coil receives the appropriate voltage signal (as specified by the manufacturer, typically 120V or 240V AC), it will mechanically trip the circuit breaker.
• After a shunt trip, the breaker must be manually reset as described in Section 5.2.
• Refer to the specific wiring diagram for your shunt trip control system for proper integration.

6. Údržba

The Eaton BR120ST circuit breaker is designed for minimal maintenance. However, periodic inspection is recommended.

• Vizuální kontrola: Annually, with power OFF, inspect the breaker for any signs of physical damage, discoloration, loose connections, or corrosion.
• Čištění: If necessary, gently clean the exterior of the breaker with a dry, lint-free cloth. Do not use liquids or abrasive cleaners.
• Testování: While not typically required for residential breakers, some commercial or industrial applications may require periodic operational testing by qualified personnel.

CAUTION: Do not attempt to open or repair the circuit breaker. There are no user-serviceable parts inside.

7. Řešení problémů

If you experience issues with your BR120ST circuit breaker, consider the following:

• Časté vypínání jističe:
  • Přetížení: Too many devices are connected to the circuit. Unplug some devices.
  • Zkrat: A direct connection between hot and neutral/ground wires. This requires immediate professional inspection.
  • Zemní spojení: Current leaking to ground. This requires professional inspection.
• Breaker Will Not Reset:
  • Ensure you are pushing the handle fully to the "OFF" position before attempting to reset to "ON".
  • If it still won't reset, there may be a persistent fault or internal damage to the breaker. Do not force it.
• Shunt Trip Not Functioning:
  • Ověřte kontrolní objemtage is present and correctly wired to the shunt trip terminals.
  • Check for loose connections in the control circuit.

If troubleshooting steps do not resolve the issue, or if you suspect a serious electrical problem, contact a qualified electrician immediately. Do not attempt repairs yourself.
