P150

The P150 is a -pole circuit breaker from Siemens, designed to deliver overcurrent and short-circuit protection for commercial and light industrial power distribution systems. Rated for 50 at 120, it serves as a dependable protective device for dedicated branch circuits, heavy equipment, and power distribution feeders requiring continuous electrical safety. Electrically, the P150 utilizes a thermal-magnetic trip unit that provides comprehensive protection against thermal overloads and sudden fault currents. Its dual-action mechanism responds effectively to sustained overcurrent conditions to prevent conductor overheating while offering fast-acting magnetic protection during severe short circuits, safeguarding downstream electrical equipment and panel wiring. Mechanically, the P150 features a high-grade molded case housing built to withstand the physical demands of commercial and industrial environments. It integrates cleanly into compatible Siemens panelboards and enclosures, offering a compact footprint for optimal panel space utilization. Fully UL listed, the P150 provides a reliable, long-term solution for new electrical installs, control panel builds, or direct maintenance replacements.
