PowerPacT H-Frame circuit breakers are designed to protect electrical systems from damage caused by overloads and short circuits. PowerPacT H-Frame circuit breakers are available with either thermal magnetic or Micrologic electronic trip protection units. This PowerPacT H-Frame circuit breaker provides thermal magnetic circuit protection with a breaking capacity of 18kA at 600VAC. All PowerPacT H-Frame circuit breakers are equipped with dual-break rotating contacts that reduce the amount of peak current during a short circuit fault. All PowerPacT circuit breakers have an integral push-to-trip button in the cover to manually trip the circuit breaker. PowerPacT H circuit breakers are available in 2 and 3-pole unit mount and I-Line constructions. This breaker has lugs on both the line and load sides. This PowerPacT H, 150A, 3 pole, circuit breaker has a breaking capacity of 18kA at 600VAC. This circuit breaker has a continuous current rating of 80%. This unit includes a factory installed 120VAC shunt trip. PowerPacT H circuit breakers comply to UL, CSA, NOM, and IEC standards and are CE marked.
