The Phoenix Contact 1020029 is a 3-pole thermal magnetic circuit breaker suitable for overcurrent protection in various applications. It is designed for DIN rail mounting and features a lever actuator for switching. This breaker has a current rating of 25A and a voltage rating of 277V AC, with dual ratings available for DC systems up to 125V.
The TMC 7 and TMC 8 series, to which this breaker belongs, offers industry-standard B-, C-, and D-trip curves, providing flexibility for different load types. The breaker complies with UL 1077, UL 489, and EN 60947-2 standards. It incorporates a trip-free, snap-action mechanism for reliable switching behavior and visual status indication for easy circuit monitoring. The series supports AC systems up to 277/480V and DC systems up to 60/125V, with specific SCCR of 7.5 kA for TMC 7 and AIC of 10 kA for TMC 8.
This circuit breaker is ideal for use in switchgear, panel boards, and electrical equipment requiring robust overcurrent protection. Its secure screw terminations ensure reliable connections. The dual-rated (AC/DC) nature helps reduce inventory requirements by covering both AC and DC applications with a single part number.
