Xantrex DC250 Enclosure Box and Breaker Xantrex/Trace 250 amp DC breaker w/ enclosureXantrex makes DC input safety a simple matter with our complete line of DC disconnects and breakers. The high amperage DC breaker is housed within a powder coated enclosure with conduit knockouts for SW and DR series inverter connection. The DC disconnects are simple to install and meet all electrical code requirements for appropriate circuit protection.DC disconnects are expandable, allowing an additional 175 or 250 amp inverter breaker to be installed for dual inverter installations. DC input/output breakers for PV, charge controllers, or DC loads can also be field installed in a DC175 or DC250. FEATURES Battery disconnect: An easy way to isolate inverter and battery Meets National Electrical Code requirement for "means of disconnection."
