ABB S202-K4 2CDS252001R0337 S200 Miniature Circuit Breaker

Description

The S202-K4 electrical assembly with Product ID 2CDS252001R0337 is a current-limiting 2-pole miniature circuit breaker designed for overcurrent and short-circuit fault management in power distribution networks. This device incorporates two alternative activation mechanisms: a delayed thermal tripping mechanism for targeted overload protection and an electromechanical magnetic tripping mechanism for rapid short-circuit mitigation. Built within the S200 product range, it features a K-characteristic curve optimized to safeguard circuitry while handling inductive current inrushes without nuisance tripping. It is suitable for deployment across residential, commercial, and diverse industrial infrastructure applications.

Features

• Incorporates a dual-pole mechanical assembly for isolated multi-line electrical protection.
• Configured with a K-type tripping characteristic curve to manage targeted motor and inductive high-inrush currents.
• Provides dual thermal-magnetic functions protecting against sustained overloads and short-circuit events.
• Employs a current-limiting design to restrict electrical fault energy passing through the downstream circuit.
• Features a Failsafe Bidirectional Cylinder-lift Terminal configuration for verified wiring connections.
• Outfitted with a toggle actuator showing a clear Red ON/Green OFF contact position indication.

Applications

• Protection of industrial inductive motor branch networks and machinery loads.
• Low-voltage commercial electrical panel assemblies and power distribution layouts.
• Residential branch sub-circuits demanding specialized high-inrush overcurrent protection.
