Eaton ES4T2R2RB Circuit Breaker - ES4 Compact IP Rated
Part Number: ES4T2R2RB
Quick Summary
Eaton ES4T2R2RB circuit breaker protects industrial panels by interrupting fault currents. Engineers often struggle to balance a compact form factor with reliable protection and straightforward wiring in crowded control cabinets. CE marking, IP protection levels, and SIL safety certifications are central to risk management, regulatory compliance, and predictable maintenance, though exact certifications depend on the variant. In this context, the ES4T2R2RB offers installation flexibility, robust short-circuit protection, and predictable trip behavior when paired with compatible Eaton components and standard panel layouts. This combination drives reduced downtime and lower lifecycle costs for automation projects and machine builders alike. For engineers, that means faster approvals, easier spare parts management, and clearer documentation across projects.
