The Phoenix Contact 1020057 is a single-pole thermal magnetic circuit breaker rated for 50A continuous current and 277V AC operation. It offers an interrupt capacity of 10kA at up to 277/480V AC and 125V DC, providing reliable overcurrent protection. The breaker supports multiple trip curves (B, C, and D) to suit different load types and inrush characteristics. Its compact width of 17.6 mm per pole makes it efficient for panel space utilization. The lever actuator allows manual on/off control and visible status indication. Designed for DIN Rail mounting, it integrates easily into industrial control panels, distribution boards, and branch circuit protection.
