Siemens offers the JXD63B400, which functions as a reliable circuit breaker within the SENTRON series. This device is characterized by its J-frame type, providing a robust structure for circuit protection. The trip unit is thermal magnetic, designed for precise performance in protecting circuits against overloads and short-circuits.
The thermal trip is fixed at a threshold to protect against overload situations over 400 amps, ensuring equipment safety under extreme conditions. The magnetic trip can be adjusted to fit specific application requirements, allowing settings from 2000 amperes up to 4000 amperes, catering to diverse electrical loads.
With an amperage capability of 400 amps and a configuration that includes three poles, this circuit breaker offers substantial protection for different circuit arrangements. It operates effectively up to a maximum voltage of 600 VAC, with a standard DC voltage rating of 250 VDC and an increased capacity of 500 VDC for series configurations.
The JXD63B400 includes ample interrupting capability at 480 volts with a substantial rating of 35 kA, which indicates its ability to handle short-circuit scenarios efficiently. Note that line and load lugs, which are crucial for connections, are typically not included with this unit, necessitating separate acquisition for complete installation.
