Schneider Electric CA2SK11B7 Control Relay 24 Vac

Product Description

The SCHNEIDER ELECTRIC CA2SK11B7 is a DIN rail-mounted control relay rated for 24 VAC operation at 50/60 Hz. It provides both a normally closed (NC) and normally open (NO) contact configuration, making it suitable for control circuit switching in a wide range of industrial and commercial electrical applications. Licensed electricians and controls technicians install this relay as part of machine control panels, motor starters, or building automation systems where low-voltage switching logic is required. Its compact form factor allows efficient use of panel space on standard DIN rail assemblies.

This relay is used in commercial and light industrial control panels where an AC control circuit at 24 VAC drives switching operations. Typical applications include HVAC control panels, motor control centers, and automated equipment where discrete on/off switching logic is needed. The NC/NO contact arrangement supports both normally energized and normally de-energized control strategies, offering wiring flexibility for a variety of ladder logic or relay logic schemes.

Key Features

• 24 VAC coil voltage rated for 50/60 Hz AC control circuits
• Dual contact configuration: one normally open (NO) and one normally closed (NC)
• DIN rail mount design for fast, tool-minimal installation in standard control enclosures
• Compact profile measuring 1.3 inches tall, 2.3 inches wide, and 2.6 inches long
• Lightweight at 0.26 pounds, minimizing load on DIN rail assemblies

Compatibility

Designed as an OEM-style replacement or direct-fit addition for control panels and relay logic systems requiring a 24 VAC, 50/60 Hz DIN rail-mounted control relay with NC/NO contact output.

Installation Notes

Installation should be performed by a licensed electrician in accordance with applicable NEC requirements and local codes. De-energize and lock out the control panel before handling or replacing any relay. Verify coil voltage matches the control circuit supply before energizing. Ensure the DIN rail is properly grounded and the relay snaps fully into place before closing the enclosure.
