1. Introduction
This manual provides essential information for the safe and effective installation, operation, and maintenance of your OJOPOV ABB S200 S203 Range 3P Miniature Circuit Breaker (MCB). Please read these instructions carefully before installation or use and retain them for future reference. This device is designed to protect electrical circuits from overcurrents, which can result from overload or short circuit.
2. Important Safety Information
WARNING: Electrical shock hazard. Installation and maintenance should only be performed by qualified personnel.
- Always disconnect power at the main supply before installing, servicing, or removing the circuit breaker.
- Ensure the circuit breaker rating matches the circuit requirements.
- Do not use the device if it appears damaged.
- Follow all local and national electrical codes and regulations.
- Never bypass or tamper with the circuit breaker.
3. Product Overview
The OJOPOV ABB S200 S203 Range 3P Miniature Circuit Breaker is a protective device designed for electrical installations. It features three poles for three-phase circuit protection and is available in various current ratings (e.g., 1A to 80A) with a C-type tripping characteristic, suitable for general applications. The device automatically trips to interrupt the circuit in case of an overload or short circuit, preventing damage to equipment and ensuring safety.
4. Setup and Installation
Installation must be carried out by a qualified electrician.
- Preparation: Ensure the main power supply to the installation is completely disconnected and locked out. Verify that the MCB's current rating and tripping curve (C-type) are appropriate for the circuit it will protect.
- Mounting: The MCB is designed for DIN rail mounting. Snap the circuit breaker onto the standard 35mm DIN rail in your electrical panel. Ensure it is securely seated.
- Wiring Connections:
- Connect the incoming phase conductors to the upper terminals (marked 1, 3, 5).
- Connect the outgoing phase conductors to the lower terminals (marked 2, 4, 6).
- Ensure all connections are firm and correct according to the wiring diagram of your electrical system.
- Terminal Tightening: Use an appropriate screwdriver to tighten all terminal screws to the manufacturer's specified torque. Overtightening can damage terminals, while undertightening can lead to loose connections and overheating.
- Verification: Double-check all wiring for correctness and security. Ensure no bare wires are exposed.
- Power Restoration: Once installation is complete and verified, restore power to the main supply.
5. Operation
- Turning ON: Push the operating lever upwards to the 'ON' position. The circuit is now energized.
- Turning OFF: Push the operating lever downwards to the 'OFF' position. The circuit is now de-energized.
- Trip Indication: If an overload or short circuit occurs, the MCB will automatically trip, and the operating lever will move to an intermediate or 'TRIPPED' position (often between ON and OFF, or fully OFF depending on the model).
- Resetting After a Trip: Before resetting, identify and rectify the cause of the trip (e.g., remove overloaded appliances, fix short circuits). Once the fault is cleared, push the lever fully down to the 'OFF' position, then push it upwards to the 'ON' position to restore power. If the MCB trips immediately again, a persistent fault exists and must be addressed.
6. Maintenance
The OJOPOV ABB S200 S203 MCB is generally maintenance-free. However, periodic visual inspections are recommended:
- Visual Inspection: Regularly check the MCB for any signs of physical damage, discoloration, or overheating.
- Terminal Connections: Periodically check the tightness of terminal connections, especially in environments with vibration or significant temperature fluctuations. Ensure power is disconnected before checking.
- Cleaning: If necessary, gently clean the exterior of the MCB with a dry, soft cloth. Do not use liquids or abrasive cleaners.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| MCB trips frequently | Overload, short circuit, faulty appliance, incorrect MCB rating. | Reduce load, identify and fix short circuit, replace faulty appliance, verify MCB rating is appropriate for the circuit. |
| MCB does not trip during a fault | Faulty MCB, fault current too low to trip (but still dangerous), incorrect MCB rating. | Immediately disconnect power. Have a qualified electrician inspect and replace the MCB if necessary. Ensure correct rating. |
| MCB does not reset | Persistent fault in the circuit, internal damage to the MCB. | Ensure the fault has been completely cleared. If it still doesn't reset, the MCB may be damaged and requires replacement by a qualified electrician. |
