ABB S400M Series MCB, 3 Poles, 13A Current Rating - S403M-C13

This 3-pole miniature circuit breaker is designed to offer precise protection against overloads and short circuits. It features a C-type tripping characteristic, suitable for circuits with high startup currents, and has a breaking capacity of 10 kA for reliable operation in demanding environments.

Features & Benefits

• Provides precise overload and short circuit protection through a thermal element for overloads and a magnetic element for short circuits

• Offers a precise calibration for tripping at specific current levels, ensuring consistent protection tailored to application needs

• Equipped with a handle mechanism that clearly indicates the ON/OFF status, facilitating easy operation and monitoring

• Compact design allows for efficient use of space in electrical panels

• Modular construction enables straightforward integration with other ABB devices, supporting flexible system upgrades

Applications

• Used in HVAC systems to safeguard circuits controlling heating, ventilation, and air conditioning equipment

• Applied in lighting control panels to protect circuits for high-intensity discharge lamps and LED systems

• Utilised in motor control centres to shield circuits driving pumps, fans, and compressors from electrical faults

• Employed in agricultural machinery distribution boards to ensure dependable protection of circuits for irrigation and processing systems

What is the purpose of the thermal element in this product?

The thermal element provides overload protection by heating up and triggering the breaker when the current exceeds a specific threshold

How does the magnetic element contribute to circuit protection?

The magnetic element quickly trips the breaker during a short circuit by responding to high fault currents

Is this product designed to handle high startup currents?

Yes, it is designed to accommodate high startup currents typically associated with inductive loads
