3.2 diegimo žingsniai
- Maitinimo atjungimas: Before beginning any work, ensure that the main power supply to the electrical panel is completely disconnected and locked out to prevent accidental re-energization.
- Montavimas: Locate an available space on the DIN-rail within your electrical distribution board. Position the SBN125 circuit breaker onto the DIN-rail, ensuring it clicks securely into place.
- Laidai:
- Connect the incoming phase (live) wire to the top terminal of the circuit breaker.
- Connect the outgoing phase (live) wire to the bottom terminal of the circuit breaker, leading to the circuit it protects.
- Ensure all wire connections are stripped to the correct length and inserted fully into the terminals. Tighten the terminal screws firmly to the manufacturer's specified torque (if available) to prevent loose connections.
- Patvirtinimas: Double-check all wiring for correctness and security. Ensure no bare wires are exposed.
- Atkurti maitinimą: Once installation is complete and verified, restore power to the main service panel.
4. Naudojimo instrukcijos
The Hager SBN125 is a manual switch designed for short-circuit protection. It has two primary operating states:
- ON Position (Up): Pushing the toggle switch upwards connects the circuit, allowing electrical current to flow.
- OFF Position (Down): Pushing the toggle switch downwards disconnects the circuit, interrupting the electrical current.
In the event of a short circuit, the device is designed to interrupt the current flow, protecting the circuit. This is a non-automatic switch, meaning it does not trip automatically like a miniature circuit breaker (MCB) for overload protection. Its primary function is to provide a manual means of isolating a circuit and to offer short-circuit protection.
5. Priežiūra
The Hager SBN125 circuit breaker requires minimal maintenance. Regular inspections are recommended to ensure continued safe operation.
- Vizuali apžiūra: Periodiškai tikrinkite grandinės pertraukiklį, ar nėra kokių nors fizinių pažeidimų, spalvos pakitimų ar atsilaisvinusių jungčių.
- Valymas: If necessary, gently clean the exterior of the circuit breaker with a dry, lint-free cloth. Do not use liquid cleaners or solvents. Ensure power is disconnected before cleaning.
- Profesionalus patikrinimas: It is advisable to have your electrical system, including circuit breakers, inspected by a qualified electrician periodically.
6. Problemų sprendimas
If you experience issues with your Hager SBN125 circuit breaker, consider the following common troubleshooting steps:
| Problema | Galima priežastis | Sprendimas |
|---|---|---|
| Circuit breaker does not switch ON. | No power to the circuit breaker; internal fault. | Check the main power supply. If power is present and the breaker still won't switch, it may be faulty and require replacement by a qualified electrician. |
| No power to the connected circuit. | Circuit breaker is OFF; loose wiring; faulty breaker. | Ensure the circuit breaker is in the ON position. Disconnect power and check all wiring connections for tightness. If issues persist, consult a qualified electrician. |
| Automatinis jungiklis karštas. | Loose connections; excessive current (overload/short circuit). | Immediately disconnect power. Check for loose connections. While this device offers short-circuit protection, persistent heat may indicate an underlying issue in the circuit or an overload condition that this non-automatic switch is not designed to trip for. Consult a qualified electrician. |
For problems not listed here or if solutions do not resolve the issue, contact a qualified electrician or Hager customer support.
