FAQs
What is the main function of the S202-B32 MCB?
The S202-B32 MCB provides overload and short circuit protection for electrical circuits, preventing damage to wiring and equipment by automatically interrupting the flow of current when a fault occurs.
What does the 'B' in S202-B32 signify?
The 'B' indicates the tripping characteristic. A Type B MCB is designed to trip when the current is 3 to 5 times the rated current, making it suitable for circuits with low inrush current, such as lighting and socket outlets.
What is the maximum current this MCB can handle?
The rated current for the S202-B32 is 32A. It is designed to protect circuits up to this current limit.
Can this MCB be used in residential and industrial settings?
Yes, the System pro M compact S200 series, including the S202-B32, is suitable for residential, commercial, and industrial applications, provided the correct tripping characteristic and configuration are chosen.
What is the breaking capacity of the S202-B32 at 400V?
At 400V AC, the breaking capacity is 6kA according to EN 60898-1 and 20kA according to IEC 60947-2.
How do I determine if I need a 2-pole (2P) MCB like this one?
A 2-pole MCB like the S202 is used to simultaneously switch both the live and neutral conductors, often required for single-phase circuits in certain installations or for specific equipment protection.
What is the operating temperature range?
The S200 series operates reliably within an ambient temperature range of -25°C to 55°C.
Troubleshooting
MCB trips frequently under normal load.
Check if the load exceeds the MCB's rated current (32A). Verify if the correct tripping characteristic (B, C, D, etc.) is selected for the type of load. If the load is stable and within limits, inspect wiring for potential short circuits or ground faults.
MCB does not trip during a fault condition.
Confirm the MCB is correctly wired and the fault is present. If the MCB is new, check for manufacturing defects. Ensure the fault current is sufficient to activate the MCB's tripping mechanism (may require professional diagnosis).
Difficulty connecting wires to terminals.
Ensure the conductor is stripped to the correct length. Use the appropriate screwdriver for the terminal type. Check that the wire gauge is within the MCB's specified range (up to 25mm² multi-wired, 35mm² solid).
Contact Position Indicator (CPI) is not visible or stuck.
Ensure the MCB handle is fully in the ON or OFF position. If the indicator is physically damaged, the MCB may need replacement.
Pros and Cons
Pros
- High reliability in overload and short circuit protection.
- Compliant with multiple international standards (IEC/EN, UL).
- Wide range of configurations and characteristics available.
- Durable construction suitable for various environments.
- User-friendly installation features like twin terminals and CPI.
Cons
- Requires professional installation and knowledge of electrical systems.
- Specific tripping characteristics must be correctly selected for the application.
- IP20 degree of protection means it's not suitable for dusty or wet environments without additional enclosure.
Setup, Compatibility & Care
Setup:
- Ensure Power is Off: Before installation, disconnect the main power supply to the circuit. Verify with a voltage tester.
- Mounting: The S200 MCB mounts onto a standard 35mm DIN rail.
- Wiring: Connect the incoming power conductor to the line terminal and the outgoing conductor to the load terminal. For double-pole or multi-pole units, connect each pole accordingly. Use conductors with the appropriate cross-section (up to 25mm² multi-wired, 35mm² solid).
- Secure Connections: Ensure all connections are tight using a screwdriver suitable for the terminals.
Compatibility:
- Standards Compliance: Compatible with IEC/EN 60898-1, IEC/EN 60947-2, and UL1077 standards.
- System Voltage: Rated for 400V AC.
- Busbars: Utilizes standard busbar systems for connection to other devices in a distribution board.
- Accessories: Compatible with a wide range of ABB System pro M compact accessories, including auxiliary contacts, alarm contacts, and remote control units.
Care:
- Cleaning: Clean the exterior of the MCB with a dry or slightly damp cloth. Avoid using solvents or abrasive cleaners.
- Inspection: Periodically inspect for any signs of physical damage or loose connections. Ensure the CPI is clearly visible.
- Environment: Install in a dry, dust-free environment with adequate ventilation, respecting the IP20 rating.
