ABB S204-C40 - 40A, 4-Pole, Circuit Breaker

ABB S204-C40 is a dependable 40A, four-pole circuit breaker designed for demanding electrical environments. Its four-pole configuration provides comprehensive protection and safe, synchronized disconnection across all lines in 3-phase four-wire systems, making it ideal for panelboards, switchboards, and control panels.

Key features and benefits

• Current rating: 40 A — precise protection for motor loads, feeders, and distribution circuits.
• Pole configuration: 4-Pole — ensures simultaneous interruption of all conductors for safer shutdown in multi-wire systems.
• Breaker type: Circuit Breaker — designed for reliable overcurrent protection in industrial and commercial applications.
• Versatile deployment: Suitable for panelboards, switchboards, and control panels, with flexible use across various industrial, commercial, and OEM environments.

Why this 4-pole design matters

In 3-phase, four-wire systems, protecting all conductors during a fault reduces arc exposure and neutral-related hazards, helping protect both equipment and personnel. The S204-C40 delivers consistent protection across multiple circuits within a single device, supporting safer start-ups and more reliable motor control center operation.

Ideal applications

• Industrial distribution panels that require robust overcurrent protection for multi-line circuits
• Motor control centers and large control panels where coordinated trip across all poles is essential
• Commercial electrical installations with three-phase services and neutral conductors
• OEM equipment where a compact, four-pole protection solution is needed for turnkey assemblies

Practical usage and installation notes

• Match the 40A rating to your feeder or motor circuit to ensure reliable protection without nuisance trips.
• Install in panelboards, switchboards, or control panels where four-pole protection supports safer, simultaneous disconnection of all lines.
• Plan wiring so all four poles are correctly connected to the corresponding conductors, preserving intended protection and system coordination.
• Use as part of a broader protection strategy in industrial, commercial, and OEM equipment to enhance overall electrical safety and uptime.

With the ABB S204-C40, you get a purpose-built, four-pole circuit breaker that aligns with robust distribution and control architectures, delivering clear, dependable protection where it matters most.
