ABB S3N050TW Three Pole Molded Case Circuit Breaker 50 Amp 600V

ABB S3N050TW is a three-pole molded-case circuit breaker rated for 50 A with a maximum voltage of 600 V, designed to protect three-phase feeders in industrial and commercial power systems. This device is part of ABB's Tmax family (S3N/TS3N), carries UL 489 and CSA C22.2 approvals, and supports voltage ratings of 240/480/600 VAC at 50/60 Hz as well as 600 VDC, making it suitable for mixed AC/DC networks. It employs a thermal-magnetic trip mechanism with a robust interrupting capacity of 25 kA at 480 VAC and 14 kA at 600 VAC, providing reliable protection for motors, pumps, fans, and other three-phase equipment in distribution panels and control cabinets. The 3-pole configuration ensures simultaneous disconnection of all phases, a feature frequently required in industrial installations, and the compact MCCB form factor integrates into standard enclosures while delivering predictable protection for power distribution and machine interfaces.
