Industrial LR12188 Three-Phase Circuit Breaker

The LR12188 is a three-pole Stab-Lok circuit breaker rated for 15 amps, manufactured for use in Federal Pacific Electric and Federal Pioneer panels that accept Stab-Lok devices. Identified by the LR12188 designation, this 3‑pole unit protects three hot legs in three‑phase installations and is intended for use in industrial or large commercial power-distribution panels that specify Stab-Lok breakers. Typical applications include protection of three‑phase feeders or branch circuits in older equipment racks and control panels designed for Federal Pioneer components, where 15 A branch protection is required for multiple loads on a common three‑phase supply. The device integrates standard Stab-Lok mounting and wiring geometry compatible with existing Federal Pacific Electric / Federal Pioneer infrastructure, enabling straightforward replacement or extension of compatible systems.
