Schneider Electric CAD50B7 Control Relay 5NO 24V

Product Description

The SCHNEIDER ELECTRIC CAD50B7 is a 5-pole normally open (5NO) AC control relay rated for 24 volts at 50/60 Hz. It is designed for use in control circuits requiring reliable switching of multiple loads from a single coil. The relay fits within motor control centers, panel boards, and industrial or commercial HVAC control panels. Licensed electricians and controls technicians are the primary installers. Its compact form factor — 4.6 inches long, 3.7 inches wide, and 2.2 inches tall — makes it suitable for installations where panel space is limited.

This relay is well-suited for commercial and light industrial applications where a low-voltage AC control circuit must switch or interlock multiple output paths simultaneously. Typical install scenarios include motor starters, building automation control panels, and HVAC equipment sequencing circuits. The 24-volt coil voltage is common in building controls and HVAC systems, making the CAD50B7 a straightforward replacement or new-installation component for those environments.

Key Features

• 5 normally open (NO) contacts for multi-path switching from a single coil
• 24 VAC coil voltage compatible with standard low-voltage control circuits
• Dual-frequency rated at 50/60 Hz for broad application compatibility
• Compact dimensions: 4.6 x 3.7 x 2.2 inches for space-conscious panel layouts
• Lightweight at 0.77 pounds for easy handling and installation

Compatibility

Designed as an OEM-style replacement or new-installation control relay for 24 VAC AC control circuit applications in commercial HVAC, motor control, and building automation panels.

Installation Notes

Installation should be performed by a licensed electrician or qualified controls technician in accordance with NEC requirements. De-energize and lock out the control panel before removing or installing the relay. Verify that the control circuit voltage matches the 24 VAC coil rating before energizing. Confirm all contact terminations are secure and that the relay is properly seated in its mounting base before restoring power.
