Description

Overview

The Siemens 5SJ4206-7HG42 Circuit Breaker is a high-performance, UL-certified miniature circuit breaker designed to deliver reliable protection for electrical systems operating at 480Y/277V. With a 10kA breaking capacity, 2-pole configuration, and C-curve tripping characteristic, this breaker ensures dependable protection against overloads and short circuits in commercial and industrial applications.

Engineered to meet UL 489 standards, this Siemens circuit breaker provides long-term operational safety, efficiency, and durability.

Benefit

  • Global Compliance: Fully certified according to UL 489 and CSA C22.2, making it suitable for export-oriented machine manufacturing and global plant engineering.

  • Enhanced Safety: The Type C trip characteristic is ideal for circuits with higher peak currents, such as motors and transformers.

  • Space-Saving Design: Compact 2-pole configuration allows for efficient use of DIN rail space in control cabinets.

  • Easy Installation: Features visible indicator windows and ergonomic terminals for secure wiring.

Function & Features

  • Overload Protection: Safely disconnects the circuit during sustained over-current conditions.

  • Short-Circuit Protection: Instantaneous tripping at 10kA to prevent damage to downstream equipment.

  • Tripping Curve C: Designed for inductive loads, allowing for moderate inrush currents without nuisance tripping.

  • Voltage Versatility: Rated for 480Y/277V AC, covering a wide range of industrial power requirements.
