Eaton EMT6-DB Electronic Motor Protection Relay, 230V AC, Black/White 066401

The Eaton EMT6-DB stands apart from conventional thermal overload relays by offering comprehensive electronic protection in a compact, directly mountable unit. It monitors motors for overload, phase failure, phase unbalance, locked rotor, and stall conditions, ensuring reliable operation in demanding industrial environments. With an adjustable trip class from 5 to 30, it adapts precisely to your motor's starting characteristics, preventing nuisance trips while safeguarding against damage.

Highlights

• Electronic motor protection relay for 230V AC control circuits
• Adjustable trip class (CLASS 5, 10, 15, 20, 25, 30) for precise matching to motor starting behavior
• Monitors overload, phase failure, phase unbalance, locked rotor, and stall
• Direct mounting design for easy installation on DIN rail or panel
• LED indicators for operational status and trip indication
• Manual, remote, and automatic reset functions for flexible operation
• Complies with UL 508, CSA C22.2 No. 14, IEC/EN 60947-8, and CE standards

In daily use

In daily operation, the EMT6-DB provides continuous protection for motors in pumps, fans, conveyors, and other critical equipment. Its wide operating temperature range of -25 to 60 °C allows use in harsh environments. The relay's auxiliary contacts (1 NO + 1 NC) enable integration with control systems for status signaling or automatic shutdown. The compact design and direct mounting save panel space and simplify wiring, while the LED indicators give at-a-glance status confirmation.
