Description

Overview

The Siemens 5SY4116-8 belongs to the premier SENTRON series of miniature circuit breakers. Designed for both residential and industrial applications, this MCB provides robust protection against overloads and short circuits. Its Type D tripping curve makes it specifically suited for inductive loads and equipment that generates significant surges upon startup.

Key Benefit

  • Enhanced Safety: Provides reliable disconnection in the event of a fault, protecting downstream equipment and personnel.

  • High Breaking Capacity: Rated at 10kA, ensuring performance even in demanding electrical environments.

  • Space-Efficient: With a compact 70mm mounting depth, it fits easily into standard distribution boards.

  • Durable Design: Siemens engineering ensures a long electrical and mechanical service life.

Function & Application

  • Tripping Characteristic D: Specifically designed for circuits with high starting currents (e.g., motors, transformers, and solenoid valves).

  • Thermal-Magnetic Release: Utilizes a thermal delay for overload protection and a magnetic release for short-circuit protection.

  • Versatile Mounting: Easy installation on standard DIN rails.
