Chint NR2-25-18 Relay 12.00-18.00A

The Chint NR2-25-18 is a high-performance thermal overload relay designed to protect three-phase AC motors from overload, phase failure, and stalled rotor conditions. Designed for use with the Chint NC1 contactor range, it provides reliable motor protection in industrial control panels, machinery, and automation systems.

With an adjustable current setting range of 12A to 18A, the relay continuously monitors motor current and automatically trips when overload conditions occur, helping to prevent motor damage, overheating, and costly downtime. The integrated phase-loss sensitivity enhances protection against single-phasing and unbalanced load conditions.

The NR2-25-18 mounts directly onto compatible NC1 contactors, creating a compact and efficient motor starter assembly. It features both manual and automatic reset modes, along with integrated STOP and TEST buttons for simplified commissioning and maintenance.
