Description

Overview

The Siemens 5SJ4 series is engineered for global applications, specifically meeting the rigorous safety requirements of the North American market. The 5SJ4108-7HG41 provides robust protection against overloads and short circuits. With its compact 70mm depth and DIN rail mounting capability, it integrates seamlessly into modern control cabinets.

Key Benefit

  • Global Compliance: Fully compliant with UL 489 and CSA C22.2, making it suitable for branch circuit protection in the US and Canada.

  • Enhanced Safety: Provides reliable 14kA interrupting capacity at 240V AC to protect sensitive downstream equipment.

  • Space-Saving Design: Its slim 1-pole profile and 70mm mounting depth optimize panel space.

  • Easy Installation: Designed for quick DIN rail mounting with secure terminal connections.

Function & Features

  • Tripping Curve C: Ideal for circuits with moderate inductive loads and high inrush currents (e.g., motors, lighting loops).

  • Thermal-Magnetic Trip Unit: Offers dual protection against long-term overloads and instantaneous short-circuit events.

  • Visible Indicators: Clear handle positions for "ON" and "OFF" status monitoring.

  • Durable Housing: Built with high-quality thermoplastic for long-term thermal stability.
