Eaton QCR3030HT Miniature Circuit Breaker

The Eaton QCR3030HT Miniature Circuit Breaker is a compact protective device in Eaton's QCR family designed to deliver overcurrent protection for electrical circuits installed in panelboards and electrical enclosures, helping to shield wiring and connected equipment from damage. As an MCB, it is intended to interrupt fault currents quickly when overloads or short circuits occur, enabling safe disconnection of a circuit and facilitating fault isolation to minimize downtime and risk of fire or equipment damage. The QCR3030HT model identifies a specific configuration within the QCR line, and the device is designed for use in systems that specify QCR components, with installation aligning to the enclosure footprint, terminal arrangement, and mounting methods used by Eaton panels. For exact current rating, breaking capacity, trip curves, terminal type, and compatible enclosure specifications, refer to the official Eaton QCR3030HT documentation and product sheets to ensure proper match with your distribution hardware. This information is essential to selecting the correct MCB for safeguarding conductors and meeting local electrical code requirements.
