Circuit Breaker Thermal 20A 240VAC 60VDC SCHURTER TA45 4430.2084

Part Overview

The SCHURTER 4430.2084 is an active thermal circuit breaker designed for panel mount applications. This component provides overcurrent protection in AC and DC circuits with a 20-ampere current rating and dual voltage capability (240V AC / 60V DC). The rocker-actuated design with orange illumination at 110V nominal supports visual status indication in industrial control and power distribution systems.

Equivalent substitute parts are identified to address inventory availability, supply chain continuity, and component sourcing requirements while maintaining identical electrical and mechanical specifications.
