Description

Overview

The Siemens 5SJ4130-7HG42 belongs to the premier line of miniature circuit breakers (MCB) specifically engineered for the North American market. It provides robust overcurrent and short-circuit protection for electrical installations. With a compact design and 10kA interrupting capacity, it ensures system reliability and safety in demanding environments.

Key Benefit

  • Global Compliance: Fully certified according to UL 489 and CSA C22.2, allowing for universal use in North American panels.

  • Enhanced Safety: Reliable "C" tripping characteristic protects against mid-level inrush currents typical in commercial lighting and small motor loads.

  • Space-Efficient: The slim 1-pole design (18mm width) saves valuable DIN rail space in control cabinets.

  • Durability: Built to Siemens’ rigorous engineering standards for long-term mechanical and electrical endurance.

Technical Function

  • Overload Protection: Thermal tripping element calibrated for 30A continuous load.

  • Short-Circuit Protection: Electromagnetic instantaneous tripping for high-fault currents.

  • Voltage Versatility: Rated for 277V AC, suitable for lighting circuits and industrial branch protection.

  • Easy Installation: Compatible with standard DIN rail mounting and features touch-safe terminals.
