1. ആമുഖം
The ABB S203-C32 is a three-pole miniature circuit breaker (MCB) designed for reliable protection of electrical circuits against overloads and short circuits. This device is part of the S200 series, engineered for easy installation and robust performance in various applications, including residential and commercial buildings.
It features a C-characteristic activation, meaning it trips when the overcurrent is 5 to 10 times the nominal current, making it suitable for circuits with moderate inrush currents. With a nominal current of 32 Amperes and a rated breaking capacity of 6 kA according to EN 60898-1, the S203-C32 provides essential safety for three-phase electrical systems.

The ABB S203-C32 circuit breaker is designed for easy installation on standard DIN rails. Its patented twin terminals with spring-loaded screws facilitate secure connection of conductors.
3.1 Mounting on DIN Rail
- Ensure the main power supply to the distribution board is switched off and locked out.
- Align the circuit breaker with the DIN rail.
- Press the circuit breaker firmly onto the DIN rail until it clicks into place. Ensure it is securely seated.

3.2 വയറിംഗ് കണക്ഷനുകൾ
The S203-C32 features three poles for three-phase circuit protection. It is equipped with twin terminals that allow for secure wiring.
- Strip the insulation from the conductor ends to the recommended length (typically 12-14 mm).
- Insert the conductors into the appropriate terminals (input and output). The terminals are designed to accept conductors up to 35 mm² cross-section.
- Tighten the terminal screws to the specified torque (refer to product markings or technical data sheet for exact torque values, typically 2.8 Nm). Ensure connections are firm to prevent loose contacts and overheating.
- Verify all connections are secure and that no bare wires are exposed, ensuring touch protection according to IP20.

4. ഓപ്പറേഷൻ
The ABB S203-C32 circuit breaker operates automatically to protect electrical circuits. It has two primary states: ON and OFF, and an automatic trip state.
- സ്ഥാനത്ത്: When the toggle switch is in the upward position, the circuit is closed, allowing current to flow.
- ഓഫ് സ്ഥാനം: When the toggle switch is in the downward position, the circuit is open, interrupting current flow. This position is used for manual disconnection.
- ട്രിപ്പ് ചെയ്ത സ്ഥാനം: In the event of an overload or short circuit, the circuit breaker will automatically trip, moving the toggle switch to an intermediate or fully down position (depending on the specific mechanism). This indicates a fault in the circuit.
To reset a tripped circuit breaker, first identify and rectify the cause of the trip (e.g., remove overloaded devices or fix short circuits). Then, firmly push the toggle switch all the way down to the OFF position, and then back up to the ON position.

5. പരിപാലനം
The ABB S203-C32 circuit breaker is designed for maintenance-free operation under normal conditions. However, periodic inspection is recommended to ensure continued reliability and safety.
- വിഷ്വൽ പരിശോധന: Regularly inspect the circuit breaker for any signs of physical damage, discoloration, or loose connections. Ensure the toggle switch moves freely.
- വൃത്തിയാക്കൽ: ആവശ്യമെങ്കിൽ, സർക്യൂട്ട് ബ്രേക്കറിന്റെ പുറംഭാഗം ഉണങ്ങിയ, ലിന്റ് രഹിത തുണി ഉപയോഗിച്ച് സൌമ്യമായി വൃത്തിയാക്കുക. അബ്രാസീവ് ക്ലീനറുകളോ ലായകങ്ങളോ ഉപയോഗിക്കരുത്. വൃത്തിയാക്കുന്നതിന് മുമ്പ് വൈദ്യുതി വിച്ഛേദിച്ചിട്ടുണ്ടെന്ന് ഉറപ്പാക്കുക.
- കണക്ഷൻ പരിശോധന: Periodically check the tightness of the terminal screws, especially after initial installation and during routine electrical system checks.
If any damage or malfunction is observed, the circuit breaker should be replaced by a qualified electrician.
6. പ്രശ്നപരിഹാരം
This section provides guidance for common issues encountered with circuit breakers.
6.1 Circuit Breaker Trips Frequently
- ഓവർലോഡ്: The most common cause. Disconnect some appliances or devices from the circuit.
- ഷോർട്ട് സർക്യൂട്ട്: A direct connection between live and neutral/ground wires. This requires immediate attention from a qualified electrician to identify and repair the fault.
- തകരാറുള്ള ഉപകരണം: An appliance connected to the circuit may be faulty and drawing excessive current. Unplug all appliances and plug them back in one by one to identify the culprit.
- അയഞ്ഞ കണക്ഷനുകൾ: Loose wiring connections can cause arcing and heat, leading to tripping. Have a qualified electrician inspect and tighten all connections.
6.2 Circuit Breaker Will Not Reset
- Persistent Fault: If the underlying overload or short circuit condition still exists, the breaker will immediately trip again when you try to reset it. Do not force it.
- ആന്തരിക ക്ഷതം: The circuit breaker itself may be damaged internally. If no fault is found in the circuit and the breaker still won't reset, it likely needs replacement.
If you are unable to resolve the issue, contact a qualified electrician for assistance.
