Digital Direct-Replacement Assemblies

Streamline retrofit projects with SEL digital direct-replacement assemblies for motor, generator, transformer, feeder, and metering protection applications. These complete, preassembled retrofit kits are designed to closely match the features, form factor, and terminal blocks of specific legacy products. They combine field-proven SEL devices with specialized mounting plates, interposing terminal blocks, and other hardware to ensure quick, seamless, and cost-effective upgrades.

Upgrade Devices Across Applications

We offer digital direct-replacement assemblies for motor, generator, transformer, bus, feeder, and metering applications.

Strengthen Systems With All-New Hardware

Legacy hardware is prone to degradation and wear that reduces the reliability of your equipment. SEL digital direct-replacement assemblies do not repurpose any existing hardware.

Simplify Installation and Configuration

Digital direct-replacement assemblies deliver an installation experience that is easy, fast, and error-free. The physical installation work for each unit can be completed within an hour—without any power tools. Panel cuts and drilling are not required; instead, each assembly fits the existing panel opening and mounting holes. Terminal block arrangements and wiring designations closely match legacy products, and SEL provides wiring labels with the retrofit kits to complete the upgrade process.

Minimize Engineering Work

Eliminate time-intensive and costly engineering tasks, such as revising drawings and diagrams. All assembly kits include wiring diagrams, so existing documentation for your system is not required for installation.

Partner With SEL on a Turnkey Solution

SEL offers services that include system design, settings conversion, installation, and commissioning—everything needed for a complete turnkey retrofit solution. We also create custom assembly designs to meet specific protection, communications, and mounting requirements.

Receive Comprehensive Support

All SEL-manufactured products and workmanship within panels and enclosures are backed by a worldwide, ten-year warranty. Diagnostic services, repairs, and local technical support are available for the lifetime of every SEL-manufactured device—at no extra cost. Third-party devices carry a transferred manufacturer warranty.

Digital Direct-Replacement Assembly Models

SEL-7250 Details

The SEL Difference

SEL uses the same world-class manufacturing principles for our direct-replacement assemblies that we use for all our industry-leading products. This allows us to design, manufacture, and test high-quality and comprehensive solutions with reduced delivery times.

Quality

We build a prototype of each new design to create pre-engineered design drawings and document the installation procedure. This process ensures that the design meets functional specifications and enables the manufacturing facility to test and confirm the assembly prior to production.

Replacement for GE Multilin 169, 269, and 369 Relays Without RTD

This assembly is equipped with the SEL-849 Motor Management Relay and the SEL-3421 Motor Relay HMI for motor applications without resistance temperature detectors (RTDs). The front of the mounting plate contains the SEL-3421 HMI and an Ethernet port for local access. The back of the plate contains the SEL-849 relay and the CT, PT, and control terminal blocks. All connections between the SEL relay and interposing terminal blocks are prewired.

Replacement for GE Multilin 169, 269, and 369 Relays With RTD

This assembly is equipped with the SEL-710 Motor Protection Relay for motor applications with up to ten RTDs. It consists of two components: a front mounting plate and a rear mounting plate. The front mounting plate contains the SEL-710 relay and the CT and PT terminal block. The rear mounting plate contains the control and RTD terminal blocks and a 24 Vdc power supply to provide wetting voltage. All connections between the SEL relay and interposing terminal blocks are prewired. For shallow compartment applications, two extension rings are available to projection-mount the SEL-710.

Replacement for GE Multilin SR469 Relays

This assembly is equipped with the SEL-710 Motor Protection Relay for motor applications with up to 12 RTDs. It consists of a mounting plate, frame, and terminal blocks, which all come preassembled as a single unit. The front of the mounting plate contains the SEL-710 relay. The back of the plate and the adjoining frame contain the CT, PT, control, and RTD terminal blocks and a 24 Vdc power supply to provide wetting voltage. All connections between the SEL relay and interposing terminal blocks are prewired.

Replacement for Westinghouse/CutlerHammer/Eaton IQ-1000, IQ-1000II, MP-3000, and MP-4000 Relays

This assembly is equipped with the SEL-849 Motor Management Relay and the SEL-3421 Motor Relay HMI for motor applications without RTDs. The front of the mounting plate contains the SEL-3421 HMI and an Ethernet port for local access. The back of the plate contains the SEL-849 relay and the CT, PT, and control terminal blocks. All connections between the SEL relay and interposing terminal blocks are prewired.
