Basler Electric, the Retrofit Relay Experts have supplied several utilities and industrials users BE1-50/51B-Plug-n-Play Single-Phase Overcurrent relays over the years. The relays are direct replacements for electromechanical CO or IAC relays. They fit into existing cases, require no panel modifications or re-wiring. Panels can literally be upgraded in hours vs. days or weeks.

Basler has expanded the line of Plug-n-Play Relays with two New Models; BE1-50/51B 235 (CO) and 237 (IAC) with Arc-flash Detection Capability. They incorporate a second low-set instantaneous with an independent contact that can be connected in a "maintenance" mode and meet NESC Arc Flash requirements.
