The QRH23B175 circuit breaker, a member of Siemens' QR Series, is specifically designed for robust electrical protection. It is a molded case type that features a thermal-magnetic trip mechanism for reliable overcurrent defense. This unit is rated for a nominal current of 175 Amperes and is suitable for three-phase applications at 240 VAC.
Employing a three-pole design, the QRH23B175 provides effective management of electrical faults with a fault current interruption capacity of 25 kA at 240V, ensuring safety in high-load conditions. The trip unit for this model is fixed and non-interchangeable, which means that adjustments to the trip settings must be made through its long-time and instantaneous options, allowing flexibility in protection levels depending on the application.
For installation, the circuit breaker connects with bolt-on electrical connections and features load-side lugs, which facilitate secure termination of conductors. The design emphasizes a non-removable installation, intended to be mounted within an enclosure, which contributes to both safety and ease of use. The QRH23B175 is a dependable solution for various electrical distribution applications, providing essential protection against overcurrents.
