FAQs
ES4T1R1B is designed for standard DIN-rail mounting. To install, snap the device onto a compatible rail, confirm proper alignment with adjacent protective devices, and tighten line and load terminals per the panel wiring diagram. After mounting, verify mechanical seating, close the panel, and perform a simple functional test to confirm correct operation.
Typical specifications for this class include a thermal-magnetic trip mechanism, a current rating suited to the protected circuit, and a standard ES4 footprint for easy system coordination. It supports DIN-rail mounting and standard industrial voltage ranges. For exact values, refer to the Eaton datasheet and your panel design requirements.
Yes, ES4T1R1B is intended for motor protection in automated lines and MCCs, offering fast fault interruption and dependable coordination with downstream devices. Use a proper enclosure to meet ambient IP requirements, and employ Eaton accessories for auxiliary indication and interlocking. Always verify that the device rating matches your motor and service conditions.
Products in this class typically align with CE marking and IEC/EN safety standards, including IEC 60947-2 for circuit-breakers. While exact certifications should be confirmed on the datasheet, selecting ES4T1R1B supports regulatory compliance in many regions and simplifies audit trails thanks to standard labeling and documented protection coordination.
The ES4T1R1B reduces downtime through reliable protection and fewer nuisance trips, lowering maintenance costs over the device lifecycle. Plan for spare parts by stocking a small subset of Eaton auxiliaries and common trip devices. Regular functional tests during preventive maintenance verify performance, helping maintain system availability and predictable total cost of ownership.
