Description

Overview

The Siemens 5SY4102-8 belongs to the renowned SENTRON series, offering industry-leading protection against overloads and short circuits. This single-pole MCB is specifically engineered for circuits with high inrush currents, making it an essential component for demanding electrical environments. With a compact 70mm mounting depth, it integrates seamlessly into standard distribution boards.

Key Benefit

  • High Breaking Capacity: Rated at 10kA, providing robust protection against high-magnitude fault currents.

  • Precision Engineering: The Type D tripping curve is ideal for inductive loads, preventing nuisance tripping during initial power surges.

  • Global Standards: Fully compliant with international safety regulations for residential and industrial applications.

  • Compact Design: Optimized for space-saving installation in control cabinets and power distribution panels.

Function & Application

  • Overload Protection: Automatically disconnects power when current exceeds 2A to prevent cable damage.

  • Short-Circuit Protection: Instantaneous tripping during electrical faults to safeguard equipment.

  • Versatile Use: Ideal for protecting transformers, solenoid valves, and motors that experience significant startup surges.
