Information About LFB3150R

The LFB3150R is a Westinghouse current limiter accessory developed for use with FB series molded case circuit breakers in low-voltage electrical distribution systems. Designed for 3-pole applications operating at up to 600VAC, the unit enhances breaker performance by limiting fault current energy during short-circuit conditions. The accessory is intended for use with thermal-magnetic F-frame Series C and FB breakers rated between 80A and 150A, supporting improved system coordination and equipment protection. Built for commercial and industrial electrical installations, the current limiter mounts directly to compatible breaker assemblies and provides up to 200kA interrupting capability at 600VAC.

Key Features:

                      • Current Limiting Protection: Reduces fault current energy during short-circuit conditions.
                      • FB Breaker Compatibility: Designed for use with Westinghouse and Eaton FB frame breakers.
                      • 3-Pole Configuration: Supports three-phase electrical distribution systems.
                      • 600VAC Rating: Engineered for medium-voltage commercial and industrial applications.
                      • High Interrupting Capacity: Provides up to 200kAIC at 600VAC for enhanced fault protection.
                      • 80A–150A Breaker Support: Compatible with thermal magnetic FB breakers within specified amp ranges.
                      • Bolt-On Installation: Mounts directly to compatible molded case circuit breaker assemblies.
                      • Industrial Distribution Application: Suitable for switchgear, panelboards, and power distribution systems.

                      The LFB3150R delivers the reliability and precision required for current limiting and electrical fault protection applications.
