Description
GE LV5F30-NF Technical Specifications:
- Voltage Rating: Low-voltage AC (typically 600VAC or below).
- Current Rating: 30A frame size.
- Poles: 3-pole configuration.
- Trip Type: Thermal-magnetic or electronic trip unit.
- Mounting: DIN rail or panel mount.
Functional Features:
- Circuit Protection: Overload, short-circuit, and ground fault protection.
- Manual Switching: Manual ON/OFF operation for maintenance.
- Visual Indication: Clear ON/OFF/TRIP indicators.
- Auxiliary Contacts: Optional auxiliary contacts for status signaling.
Application Scenarios:
- Motor branch circuit protection.
- Distribution panel feeders.
- Industrial machine power control.
- Lighting and HVAC circuits.
Performance Parameters:
- Interrupting Capacity: Rated for specific short-circuit current levels.
- Mechanical Life: High-cycle rated for frequent switching.
- Electrical Life: Optimized for load switching.
Material Composition & Structural Characteristics:
- Contacts: Silver-alloy contacts for low resistance.
- Housing: Flame-retardant thermoplastic.
- Trip Unit: Precision bimetallic or electronic components.
- Terminals: Screw or bolt-type terminals.
Working Principle: Under normal conditions, the breaker allows current flow. During an overload, the thermal element heats and trips the mechanism. During a short circuit, the magnetic element instantly trips the breaker. The manual operator allows for safe isolation.
Installation Requirements:
- Sizing: Properly size for load current and fault current.
- Wiring: Use appropriate wire size and torque.
- Clearance: Maintain adequate spacing for arc flash safety.
- Testing: Perform primary and secondary injection testing.
Usage Precautions:
- Safety: Follow arc flash safety procedures.
- Maintenance: Periodically exercise and test the breaker.
- Replacement: Use identical or approved equivalent.
- Environment: Protect from excessive dust and moisture.
