ABB S400M Series Miniature Circuit Breaker, 16A Current, 415V Rated AC Voltage - 2CCS573103R8467

This miniature circuit breaker provides overcurrent protection for low-voltage installations and is intended for four-pole distribution circuits. It operates within three-phase systems at rated AC voltages up to 415V and uses a combined thermal and electromechanical trip arrangement to interrupt fault currents. The device is suited to panel mounting where standardised protection and a Compact footprint are required.

Features and Benefits:

• 52.20kA breaking capacity protects against high fault currents
• Type K tripping characteristic handles motor-start and inductive loads
• 4-pole configuration enables simultaneous multi-phase disconnection
• 16A current rating supports moderate load circuits
• I/O reset actuator permits clear manual on/off operation

Applications

• Suitable for three-phase distribution panels in commercial buildings
• Ideal for circuits with frequent motor starts and inductive loads
• Used with switchboards requiring coordinated multi-pole protection
• Can be used for feeder protection where high interrupting capacity is needed

What earth and enclosure protection level does it provide?

The enclosure meets IP20 protection, which guards against access to hazardous parts and solid objects larger than 12 mm.

How are the conductors terminated?

Conductors connect via screw terminals designed for secure clamping under vibration.

What standards guide its short-circuit performance?

Short-circuit interruption and design align with IEC/EN 60947-2 requirements.

Which mechanism initiates trip under overload and short-circuit?

Thermal action responds to prolonged overload while the electromechanical release trips on Rapid fault currents.
