PowerPacTP-Frame circuit breakers are designed to protect electrical systems from damage caused by overloads and short circuits. PowerPacT P-Frame circuit breakers have either a fixed long time electronic trip unit, ET 1.0I, or Micrologic trip units. Micrologic trip units can be interchanged in the field to allow for maximum flexibility; the basic electronic trip unit doesn't have that interchangeability. This circuit breaker has a Micrologic Interchangeable Standard with a 5.0 trip unit and an LSI function. All PowerPacT circuit breakers have an integral push-to-trip button in the cover to manually trip the circuit breaker. PowerPacT P circuit breakers are available in 2, 3, and 4-pole unit mount, I-Line, or drawout construction. This unit has lugs on both the line and load sides. This PowerPacT P, 1000A, 3 pole, circuit breaker has an interrupting rating of 18kA at 600VAC. This circuit breaker has a continuous current rating of 100%. PowerPacT P circuit breakers comply to UL, CSA, NOM, and IEC standards and are CE marked.
