Schneider Electric CAD32B7 Control Relay 24V Ac

Product Description

The SCHNEIDER ELECTRIC CAD32B7 is a multi-contact control relay rated for 24 volts AC at 50/60 Hz. It provides a 2NC/3NO contact configuration, giving installers two normally closed and three normally open switching paths in a single device. This relay is used in low-voltage control circuits to switch, sequence, or interlock loads across HVAC, industrial, and building automation systems. Licensed electricians and HVAC controls technicians are the primary trade professionals who specify and install this device. The compact form factor and standard DIN-rail-compatible sizing make it a straightforward drop-in for panel and equipment enclosure work.

The CAD32B7 is suited for residential and light commercial control panel applications where a reliable multi-contact relay is required. Typical install scenarios include fan coil unit control boards, air handling unit interlock circuits, and building automation panel assemblies operating on 24-volt AC control power. Its 50/60 Hz rating covers both North American and international frequency standards, broadening its use across varied electrical environments.

Key Features

• 2NC/3NO contact configuration provides five independent switching paths in one relay body
• 24 volts AC coil voltage at 50/60 Hz suits standard low-voltage control circuits
• Compact body measuring 2.2 inches high, 3.7 inches wide, and 4.6 inches in length
• AC control circuit type rated for 50/60 Hz dual-frequency operation
• Lightweight at 0.77 pounds, reducing panel load and simplifying mounting

Compatibility

Designed as an OEM-style replacement control relay for low-voltage AC control circuits operating at 24 volts, 50/60 Hz in HVAC, building automation, and light industrial panel applications.

Installation Notes

Installation should be performed by a licensed electrician or qualified controls technician in accordance with NEC requirements for control circuit wiring. De-energize and lock out the control panel before removing or installing the relay. Verify coil voltage at the panel matches the 24-volt AC rating of the CAD32B7 before energizing. Inspect all contact terminals for secure termination and confirm contact configuration matches the circuit diagram before restoring power.
