ABB S3N 3P 150A: High-Performance Molded Case Circuit Breaker for Industrial Power Protection
Product Overview
The ABB S3N 3P 150A is a robust molded case circuit breaker (MCCB) designed for critical power distribution applications in industrial, commercial, and infrastructure settings. As part of ABB’s S3N series, this three-pole (3P) breaker provides reliable protection against overloads, short circuits, and ground faults, ensuring safe and efficient operation in low-voltage systems up to 690V AC6. With a 150A rated current and 50kA short-circuit breaking capacity (Icu), the ABB S3N 3P 150A is ideal for demanding environments such as manufacturing plants, data centers, and power generation facilities.
Featuring a thermal-magnetic trip unit, the ABB S3N 3P 150A offers adjustable overload protection (Ir) and short-circuit protection (Im), allowing precise customization to match specific load requirements25. Its compact design (170 x 108 x 107 mm) and DIN rail mounting compatibility enable easy integration into standard control panels, while the IP20-rated enclosure safeguards against dust and accidental contact5. The breaker’s self-diagnostic LED indicators provide real-time status feedback, simplifying maintenance and reducing downtime.
Compliant with IEC 60947-2 and UL 489 standards, the ABB S3N 3P 150A ensures global interoperability and meets the highest safety requirements for mission-critical applications. Its modular design supports optional accessories such as auxiliary contacts, shunt trip coils, and communication modules, enhancing flexibility for advanced monitoring and automation10.
