Schneider Electric CA2KN31G7 Control Relay 120VAC

Product Description

The SCHNEIDER ELECTRIC CA2KN31G7 is a control relay designed for AC control circuits operating at 120 volts and 50/60 Hz. It provides 3 normally open (NO) and 1 normally closed (NC) contacts, making it well suited for switching and logic control applications in industrial and commercial electrical systems. The relay is compact, with a footprint under 2.5 inches in any dimension, and weighs 0.39 pounds. Licensed electricians and industrial controls technicians are the primary installers of this device in panel and machine control applications.

The CA2KN31G7 is used in control panels, motor control centers, and automation systems where multiple switching outputs are needed from a single coil. Its 3NO/1NC contact configuration supports interlock, sequencing, and load-switching logic typical in HVAC controls, conveyor systems, and industrial automation panels. The 50/60 Hz rating makes it compatible with standard North American electrical infrastructure.

Key Features

• 120 VAC coil voltage at 50/60 Hz for standard North American control circuits
• 3 normally open and 1 normally closed contact configuration
• Compact body measuring 2.5 inches wide, 2.4 inches long, and 2 inches tall
• Lightweight at 0.39 pounds for easy panel integration
• AC control circuit type for compatibility with standard relay logic systems

Compatibility

Designed as an OEM-style replacement control relay for AC control circuits operating at 120 volts, 50/60 Hz, in industrial, commercial, and HVAC panel applications.

Installation Notes

Installation should be performed by a licensed electrician in accordance with NFPA 70 (NEC) requirements. De-energize and lockout/tagout the control panel before removing or installing the relay. Verify coil voltage and contact configuration match the existing circuit before energizing. Ensure all terminal connections are secure and the relay is properly seated in its base or mounting rail before restoring power.
