Product information

Description

The Schneider Electric CA3KN31BD3 is a professional-grade auxiliary relay engineered for precise control circuit switching in industrial environments. With a 10 A current rating and a 24V DC coil voltage, this compact device provides reliable signal management and enhances the operational safety of complex electrical control systems. Its robust design ensures consistent performance and durability, making it a dependable component for demanding automation applications.

Advantages

This auxiliary relay offers exceptional reliability due to its high-quality construction and standardized design. Its compact footprint allows for efficient space utilization within control panels, while the 24V DC coil operation ensures compatibility with modern low-voltage control architectures. The device is built to withstand rigorous industrial conditions, providing long-term stability and reducing the need for frequent maintenance in critical electrical installations.

Suitable for

  • Industrial automation control circuits
  • Signal switching in electrical panels
  • Integration into PLC-based control systems
  • General purpose auxiliary switching tasks

When it may not be suitable

This relay is not intended for switching high-power loads directly, such as large motors or heating elements, as it is designed specifically for auxiliary control signals. It is also not suitable for AC coil voltage applications, as it is strictly engineered for 24V DC operation.

Key specifications

  • Rated operational current: 10 A
  • Coil voltage: 24V DC
  • Contact configuration: 3 Normally Open (NO) and 1 Normally Closed (NC)
  • Mounting type: DIN rail or screw mounting
  • Compact modular design

How to use

The relay should be installed by a qualified professional within a suitable electrical enclosure. Mount the device onto a standard DIN rail or secure it using the provided screw mounting points. Connect the 24V DC control signal to the coil terminals, ensuring correct polarity. Wire the auxiliary contacts into your control circuit according to your specific system schematic, verifying that the load does not exceed the 10 A rating.

What to consider before purchase

  • Verify that your control system provides a stable 24V DC power supply.
  • Ensure the contact configuration (3NO/1NC) meets your specific circuit requirements.
  • Check the available space in your control cabinet for mounting.
  • Confirm that the environmental conditions are within the specified operating temperature range.

Usage recommendations

Always ensure the power supply is disconnected before performing any wiring or maintenance on the relay. Regularly inspect the terminal connections to ensure they remain tight and free from oxidation to maintain optimal electrical conductivity.
