Information About LDL36400U31X
The LDL36400U31X is a molded case circuit breaker from the PowerPacT L-Frame family developed for reliable protection of low-voltage distribution systems. Its robust construction incorporates dual-break rotating contacts that limit peak current stresses during short-circuit events. The breaker is compatible with unit mount, I-Line, and drawout configurations, enabling integration into a wide range of switchboards and panelboards. Designed around electronic protection technology, it supports precise coordination and compliance with international electrical standards.
Key Features:
- L-Frame construction: Supports high-current applications within compact molded case dimensions.
- Electronic trip unit: MicroLogic 3.3 technology enables accurate long-time and instantaneous protection.
- Dual-break rotating contacts: Reduces peak let-through current during short-circuit faults.
- 3-pole configuration: Provides balanced protection for three-phase power systems.
- Push-to-trip mechanism: Allows manual verification of mechanical and tripping functionality.
- High voltage capability: Rated for operation up to 600 Vac in distribution environments.
- Lug-mounted terminals: Accommodates large aluminum or copper conductors for secure connections.
The LDL36400U31X delivers the reliability and precision required for controlled protection of industrial and commercial power distribution circuits.
