SEL Direct-Replacement Assemblies

SEL Direct-Replacement Assemblies

Streamline retrofit projects with complete assemblies designed to match the features, form-factor, and terminal blocks of legacy relays.

SEL direct-replacement assemblies are complete, preassembled retrofit kits—each designed to match the features, form-factor, and terminal block arrangement of a specific legacy relay. These assemblies combine field-proven SEL relays with specialized mounting plates, interposing terminal blocks, and other hardware to ensure quick and seamless upgrades.

Streamlined Installation and Configuration

Each assembly is designed to fit the existing panel opening and mounting holes, minimizing the need for panel modifications. The terminal block arrangement and wiring designations closely match the prior installation, which dramatically reduces the impact on drawing sets, the likelihood of installation errors, and the time required for installation.

Purpose-Built Replacements

The following assemblies are now available, providing direct replacements for a range of legacy relays. SEL Engineering Services also accommodates requests for custom assembly designs to meet specific protection, communications, and mounting requirements.
