Schneider Electric RSB1A160F7 General Purpose Relay 4000VA

Product Description

The SCHNEIDER ELECTRIC RSB1A160F7 is an electromechanical plug-in general purpose relay rated at 4,000 VA with a 16-amp contact capacity at 250 VAC or 28 VDC. The coil operates at 120 VAC, and the relay features a single-changeover (1CO) contact form. Compact and socket-mountable, this relay is designed for control panel and industrial automation applications where reliable switching of moderate loads is required. It meets CSA, UL, and IEC standards, making it suitable for use in equipment that must comply with North American and international electrical codes. Electricians and control panel builders install this relay in relay sockets on DIN-rail or panel-mount assemblies.

This relay is used in light commercial and industrial control circuits, including HVAC control panels, motor starter auxiliary circuits, and general switching applications. Its plug-in design allows for quick field replacement without rewiring the socket. The 1CO contact form supports both normally open and normally closed switching in a single relay body, giving installers flexibility in ladder logic and control wiring layouts. It is sized for 120 VAC control voltage circuits, which are standard in North American commercial and industrial equipment.

Installation Notes

Installation of this relay is typically performed by a licensed electrician or qualified control panel technician. De-energize and lock out the panel before inserting or removing the relay from its socket. Verify that the socket type, coil voltage, and contact rating match the relay specifications before energizing. Installation must comply with applicable sections of the NEC and any equipment-specific wiring diagrams.
