SCHURTER 4411.0018 Circuit Breaker Thermal 16A 277VAC 28VDC Equivalent & Substitute Parts

Part Overview

The SCHURTER 4411.0018 is a thermal circuit breaker designed for panel mount applications with a 16A current rating across 277V AC and 28V DC voltage specifications. This single-pole, push-to-reset breaker operates in the T13 series and maintains active product status with ROHS3 compliance. Substitute parts are identified when inventory constraints, lead time requirements, or procurement preferences necessitate alternative sourcing while maintaining identical electrical and mechanical specifications.
