Schneider Electric 9999CLM1 Current Limiting Module

Schneider Electric 9999CLM1 Current Limiting Module is a dedicated accessory for MAGGUARD circuit breakers used with FA-frame NEMA contactors. This module provides fast current limiting during short-circuit events, reducing let-through energy to downstream equipment, and is rated for up to 600 V AC systems. Specifically described for FA-frame MAGGUARD assemblies, the 9999CLM1 supports 3- to 7-A configurations, enabling protection for a range of motor loads and other inductive circuits without requiring separate protective devices. The unit integrates with Square D by Schneider Electric products in industrial control panels and switchgear, offering a compact solution that complements MAGGUARD protection while maintaining compatibility with standard FA-frame contactors. With the combination of a current-limiting module and MAGGUARD breaker, installers can achieve quicker fault isolation and improved equipment protection in motor control and automation applications, where accurate current limiting and reliable short-circuit protection are critical. The 9999CLM1's 600 V rating and FA-frame compatibility make it suitable for typical commercial and light-industrial electrical distributions that use Schneider Electric's NEMA-defined protection scheme.
