Information About LLA36400U31X
The LLA36400U31X is part of the Schneider Electric PowerPacT L-Frame family, engineered for high-performance protection in low-voltage power distribution systems. Its molded case design incorporates dual-break rotating contacts that reduce peak let-through current during short-circuit events, improving system protection and equipment longevity. The breaker is equipped with an electronic MicroLogic 3.3 trip unit, providing accurate long-time and instantaneous protection tailored to demanding load conditions. Typical applications include commercial and industrial distribution panels requiring high interrupting capacity and I-Line mounting compatibility.
Key Features:
- PowerPacT L-Frame Architecture: Designed for high-capacity distribution line protection in commercial and industrial systems.
- MicroLogic 3.3 Electronic Trip Unit: Provides precise LI protection with adjustable long-time pickup settings.
- High Interrupting Capacity: Rated at 50 kA at 600 V AC for robust short-circuit protection.
- Dual-Break Rotating Contacts: Reduces peak fault current to minimize thermal and mechanical stress.
- Three-Pole Configuration: Supports balanced protection of three-phase power systems.
- I-Line Line-Side Connection: Enables fast, secure installation with reliable bus engagement.
- Load-Side Lug Terminations: Supports large conductors for high-current applications.
- 80% Continuous Rating: Suitable for continuous-duty operation within rated limits.
The LLA36400U31X delivers the reliability and precision required for protecting high-current distribution circuits in demanding commercial and industrial electrical environments.
