ABB S300P Series Miniature Circuit Breaker, 40A Current, 25kA Breaking Capacity - 2CDS383001R0404


This miniature circuit breaker provides overcurrent protection for three-phase installations on DIN-rail systems, offering coordinated tripping behaviour for general electrical distribution and control panels. It is designed for environments requiring both AC and DC operation, with a toggle reset and screw connection for routine maintenance and wiring.

Features and Benefits:


• Type C tripping ensures selective protection against moderate inrush currents
• 25kA breaking capacity limits fault energy and protects downstream equipment
• 3 poles support three-phase circuit interruption without additional devices
• 125V DC and 415V AC ratings enable mixed-voltage installations
• Toggle reset with screw terminals simplifies manual resetting and secure wiring

Applications


• Suitable for industrial three-phase distribution boards
• Used with control panels requiring DIN-rail mounting
• Ideal for installations needing DC protection up to 125V
• Can be used for branch-circuit protection at 415V AC
• Used for retrofit replacements in Compact electrical enclosures

What mounting method does it use?


It clips directly onto a DIN rail for Rapid installation and removal.

How is the unit secured electrically to conductors?


Conductors are terminated via screw-type terminals providing mechanical and electrical retention.

What ingress protection levels are provided?


It carries IP20 and IP40 ratings indicating Basic finger protection and partial enclosure shielding.

Which tripping characteristic suits motor loads?


A Type C characteristic accommodates moderate motor-starting currents while protecting against faults.
