Chint NR2-25-0.40 Relay 0.25-0.40A

The CHINT NR2-25-0.40 is a thermal overload relay designed to protect three-phase electric motors from damage caused by overload, phase loss, or prolonged overcurrent conditions. It is part of the NR2-25 series, a widely used industrial protection range that pairs with contactors to provide reliable motor control and safeguarding in industrial and commercial electrical systems.

This specific model has an adjustable current setting range of 0.25A to 0.40A, making it suitable for smaller motor applications where precise overload protection is required.

Key Features

• Adjustable current range: 0.25–0.40A
• Designed for use with AC motor contactors (typically CHINT NC1 series)
• Provides overload and phase-loss protection
• Bimetallic thermal trip mechanism for reliable operation
• Manual/automatic reset options (depending on configuration)
• Trip indicator for easy fault identification
• Ambient temperature compensation for stable performance
