FAQs
What is the difference between tripping mechanisms?
The S200M features a delayed thermal mechanism for gradual overload protection and an electromechanical mechanism for rapid response to sudden short circuits.
What does '4 Pole' mean for this circuit breaker?
A 4-pole breaker protects three phases and the neutral conductor. It's typically used in 3-phase systems.
What is the purpose of the 'C' in 'Type C'?
Type C refers to the tripping characteristic. Type C breakers are designed to handle moderate inrush currents, making them suitable for inductive loads like motors and transformers.
What is the breaking capacity of this model?
This specific model (S204M-C20) has a breaking capacity of 25 kA.
Can I use this breaker in a residential application?
Yes, the S200M series is suitable for residential, commercial, and industrial applications, provided the specifications (pole count, current rating, characteristic) match the circuit requirements.
How do I select the correct circuit breaker?
Consider the type of load, expected inrush current (influencing the characteristic B, C, D), the circuit's rated current, and the prospective fault current at the installation point (influencing breaking capacity).
What are the dimensions of this circuit breaker?
This model has dimensions of 88mm in length, 70mm in width, and 69mm in depth.
Troubleshooting
Breaker trips frequently
Check for overloaded circuits, short circuits, or faulty appliances connected to the circuit. Ensure the breaker's rating and tripping characteristic are suitable for the load.
Breaker will not reset after tripping
The fault condition may still be present. Investigate and rectify the overload or short circuit. If the breaker is damaged, it must be replaced.
No power to the circuit after resetting breaker
Verify that the circuit breaker is fully engaged. Check upstream power supply and downstream wiring connections. If the breaker appears functional but there is no power, consult a qualified electrician.
Pros and Cons
Pros
- Provides reliable protection against both overloads and short circuits.
- High breaking capacity ensures safety in demanding applications.
- Versatile range of configurations and characteristics fits various installation types.
- Compliant with international standards for guaranteed performance.
- Compact design and optional space-saving auxiliary contacts.
Cons
- Requires careful selection of the correct tripping characteristic (B, C, D, etc.) for the application.
- Breaking capacity must be verified against the fault current at the installation point.
- Installation requires electrical expertise and adherence to safety regulations.
- Specific model details (e.g., 4-pole) may not suit all single-phase applications.
- Material composition (Metal, Plastic) may vary in specific environmental resistance compared to specialized types.
Setup, Compatibility & Care
Setup: The S200M circuit breaker is designed for DIN rail mounting. Ensure the power supply is de-energized before installation. Slide the breaker onto the DIN rail and secure it using the mounting clip. Connect the conductors to the appropriate terminals according to the wiring diagram and local electrical codes.
Compatibility: This model is compatible with standard 35mm DIN rails. It is suitable for residential, commercial, and industrial applications. When selecting a breaker, ensure the rated current, tripping characteristic (Type C is general-purpose, suitable for loads with moderate inrush currents), and breaking capacity are appropriate for the circuit being protected.
Care: Minimal care is required for these devices under normal operating conditions. Periodically inspect the enclosure for damage. Ensure ventilation around the breaker is not obstructed. Avoid exposing the breaker to excessive dust, moisture, or corrosive environments. Regular professional electrical inspections are recommended for the entire electrical system.
