Description

Overview

The Siemens 5SJ4101-7HG42 Circuit Breaker is a high-performance, single-pole circuit breaker designed to provide superior protection for electrical circuits. This model offers a current rating of 1A, operates at 277V, and is rated to handle up to 10kA of short-circuit protection. It adheres to UL 489 standards, making it reliable and compliant for use in residential, commercial, and industrial applications. With a C-curve characteristic, this breaker is ideal for circuits with moderate inrush currents, offering both protection and efficiency.

Key Benefit

  • 10kA Short-Circuit Rating: Ensures robust protection against overloads and short circuits, safeguarding your electrical systems.

  • C Curve Characteristics: Provides a delayed tripping action for moderate inrush currents, suitable for motors, lighting, and other inductive loads.

  • UL 489 Compliant: Meets industry standards for safety, ensuring quality and reliability in all installations.

  • 1A Rating: Ideal for low current circuits, providing precise protection without unnecessary power cuts.

  • Compact & Durable Design: Easy to install and built to last, offering long-term, trouble-free service.

  • 1-Pole Configuration: Perfect for single-phase circuits, offering a space-efficient solution.

Function

This Siemens circuit breaker protects electrical circuits by automatically interrupting the flow of current during overloads or short circuits. The C curve ensures it only trips under excessive fault conditions, preventing unnecessary downtime while maintaining the safety of your system.
