Schneider Electric CA3SK11BD Control Relay 24 Vdc

Product Description

The SCHNEIDER ELECTRIC CA3SK11BD is a 24 VDC control relay with one normally closed (NC) and one normally open (NO) contact configuration. It mounts on standard DIN rail, making it a compact and straightforward component for low-voltage control circuits in industrial and commercial electrical panels. The relay measures 2.7 inches in length, 2.4 inches in width, and 1.3 inches in height, and weighs 0.28 pounds. Licensed electricians and control panel builders install this relay where reliable switching of control-circuit signals is required.

The CA3SK11BD is suited for use in control panels, machine automation enclosures, and building automation systems that require DIN rail-mounted switching components. Its 24 VDC coil voltage makes it compatible with common low-voltage DC control circuits found in industrial and commercial HVAC controls, motor starters, and programmable logic controller (PLC) output circuits. The NC/NO contact arrangement provides flexible wiring options for both energize-to-open and energize-to-close applications.

Key Features

• 24 VDC control circuit for compatibility with low-voltage DC panel wiring
• One NC and one NO contact for flexible switching configurations
• DIN rail mount for fast, tool-minimal installation in standard enclosures
• Compact footprint: 2.7 x 2.4 x 1.3 inches
• Lightweight at 0.28 pounds for easy panel layout

Compatibility

Designed as an OEM-style replacement for DIN rail-mounted 24 VDC NC/NO control relays in industrial and commercial control panel applications.

Installation Notes

Installation should be performed by a licensed electrician following applicable NEC requirements. De-energize and lock out the control panel before installing or replacing any relay. Snap the relay onto a grounded DIN rail and verify all wiring connections are secure before restoring power. Confirm the control circuit voltage matches the 24 VDC coil rating before energizing.
