ABB S202M-K2UC 2CDS272061R0277 S200MUC Miniature Circuit Breaker

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.

Installation Guidelines

• DIN Rail Installation: Mount the hardware securely onto a standard symmetrical tracking option, such as TH35-15 or TH35-7.5 mounting rails in accordance with the IEC 60715 standard layout.
• Orientation Versatility: Designed to be mechanically seated at any functional structural mounting position inside the automation control cabinet.
• Polarity Enforcement: Ensure careful inspection and execution of the terminal wiring connections relative to the marked polarity designations for direct current operations.
• Torque Specifications: Use a standard Pozidriv 2 screwdriver tool to verify that all cylinder-lift terminal screws are anchored securely to a recommended value of 2.8 N-m (25 in-lb for UL/CSA arrangements).
