Description

Overview

The Siemens 5SY4110-8 is a 1-pole miniature circuit breaker (MCB) designed for demanding industrial and commercial electrical systems. As part of the trusted Siemens Sentron family, this device ensures the safety of electrical installations against overloads and short circuits.

With a Type D tripping curve, this unit is specifically optimized for circuits with high inrush currents, such as motors, transformers, and solenoid valves. Its compact 70mm depth allows for easy integration into standard distribution boards and control cabinets.

Key Benefit

  • Enhanced Safety: Provides reliable protection for personnel and assets with a 10kA switching capacity.

  • Industrial Durability: Built to withstand rigorous environments and frequent switching cycles.

  • Easy Installation: Standard DIN rail mounting and a compact 70mm profile save time and space during assembly.

  • Global Compliance: Meets international standards for safety and performance (IEC/EN).

Technical Function

  • Overload Protection: Thermal tripping mechanism for long-term overcurrent.

  • Short-Circuit Protection: Electromagnetic tripping for instantaneous disconnection during faults.

  • Type D Characteristic: Delayed tripping to prevent nuisance blowing during high-starting current peaks.
