Chint NR2-25-25 Relay 17.00-25.00A

The Chint NR2-25-25 is a reliable thermal overload relay designed to protect three-phase AC motors from overload, phase failure, and excessive current conditions. Engineered for use with the Chint NC1 contactor range, it provides dependable motor protection in industrial control panels, machinery, and automation systems.

Featuring an adjustable current setting range of 17A to 25A, the relay continuously monitors motor current and trips when overload conditions occur, helping to prevent motor damage, overheating, and costly downtime. The unit incorporates phase loss sensitivity for enhanced protection against single-phasing faults and unbalanced load conditions.

The NR2-25-25 mounts directly onto compatible Chint NC1 contactors, creating a compact and efficient motor starter assembly. It includes both manual and automatic reset modes, along with integrated STOP and TEST buttons for easy commissioning and maintenance.
