Eaton ES4T2R1GF1B Electrical Protection & Control - Key Spec
Part Number: ES4T2R1GF1B
Quick Summary
The ES4T2R1GF1B provides overcurrent protection for industrial panels and motor control centers. This solution helps engineers prevent nuisance trips while maintaining steady production and ease of maintenance. Many facilities struggle with protection coordination, leaving critical equipment exposed to faults; this device enables precise tuning, fast diagnostics, and reliable selective tripping to minimize downtime. The family aligns with CE conformity and UL safety expectations, and its rugged IP-rated enclosure stands up to dusty and damp environments common in factories. Integrated with Eaton's protection ecosystem, it supports streamlined procurement, service alignment, and long-term lifecycle value. In practice, users gain safer operation, faster fault localization, and predictable, compliant protection for critical workloads.

FAQs
To install ES4T2R1GF1B on a DIN rail, verify clearance and mounting space, then snap the unit onto the rail until it clicks securely. Connect line and load conductors per the enclosure schematic, tighten terminals to the recommended torque, and perform a functional check with the commissioning tool or test button. Label the device and document protection settings for audits.
ES4T2R1GF1B provides overcurrent protection with adjustable trip thresholds and time-current characteristics, enabling selective coordination with upstream devices. By tuning the protection settings, downstream devices trip only for their designated fault, preserving healthy sections of the system and reducing full-panel outages. Regular coordination testing ensures alignment with the protection philosophy and minimizes downtime.
Yes. The ES4T2R1GF1B is designed for motor control centers and switchgear where reliable overcurrent protection and quick fault localization matter. Its DIN rail mounting and Eaton ecosystem compatibility simplify integration with existing MCCs, while standardized wiring and diagnostics help maintenance teams service motor feeders and distribution panels with minimal disruption.
In regulated environments, expect CE conformity and safety compliance considerations relevant to electrical protection devices. Ensure proper labeling, documentation, and periodic functional testing per plant procedures. Verify compatibility with your regional electrical standards and the control-system architecture, and coordinate with your safety officer to maintain audit readiness during inspections. Also consider shelf-life documentation for long-term reliability.
Maintenance and ROI are driven by downtime reduction, faster fault localization, and streamlined expansion. With clear diagnostics and standardized wiring, technicians spend less time on troubleshooting and commissioning. Over the device life, protection stability reduces repair costs and supports predictable maintenance budgets. By standardizing on a single protection platform, plants can simplify spare parts management and training, delivering tangible total cost of ownership savings.
