Product Description

Description

The S202M-K2UC universal current configuration with Product ID 2CDS272061R0277 is a 2-pole miniature circuit breaker engineered to provide flexible overcurrent protection and short-circuit fault mitigation in both alternating current (AC) and high-voltage direct current (DC) industrial networks. As a modular component of the System pro M compact S200MUC series, this device incorporates a delayed thermal tripping mechanism for overload safety alongside an electromechanical magnetic tripping mechanism tailored for instantaneous short-circuit protection. It operates across a wide performance range with a certified breaking capacity up to 10 kA at 440 V AC/DC, making it highly compatible with specialized electrical infrastructure layout panels, field distribution systems, and global industrial automation backup assemblies.

Features

  • Outfitted with a 2-pole hardware matrix ensuring reliable multi-line overcurrent protection and circuit isolation.
  • Utilizes a flexible universal current configuration certified for execution across both AC and DC wiring topologies.
  • Designed with a K-characteristic tripping curve optimized to mitigate specific inductive current spikes and fault profiles.
  • Employs a failsafe bi-directional cylinder-lift terminal configuration to guarantee secure, vibration-resistant cable clamping.

Applications

  • High-voltage direct current distribution setups, transportation infrastructure, and photovoltaic branch panel assemblies.
  • Multi-axis industrial automation systems, heavy-duty motor control panels, and field machinery control loops.
  • Complex low-voltage networks requiring high short-circuit breaking thresholds and multi-standard component flexibility.
