Description
GE THPR3616ET1
Technical Specifications:
- Brand: General Electric (GE)
- Model: THPR3616ET1
- Product Type: Molded Case Circuit Breaker (MCCB)
- Poles: 3-Pole
- Voltage Rating: 600V AC
- Current Rating: 1600 Amps
Functional Features:
- Superior Fault Interruption: Provides high-interrupting capacity to safely clear short circuits and severe overloads without catastrophic failure.
- Thermal-Magnetic Protection: Utilizes a dual-element trip mechanism to protect against both prolonged overloads and instantaneous short circuits.
- Rugged Enclosure: Housed in a durable, flame-retardant thermoplastic case that ensures operator safety and complete arc containment.
Application Scenarios:
Widely deployed as main feeders or large branch circuit protectors in industrial manufacturing plants, commercial high-rises, and heavy machinery power distribution panels.
Performance Parameters:
- Interrupting Rating: High short-circuit current rating (SCCR) suitable for high-energy power systems.
- Mechanical Life: Exceptional cycle life for frequent switching, testing, and maintenance operations.
Material Composition:
Encased in a high-impact, glass-filled thermoplastic housing. Internal contacts are crafted from silver-alloy composites to minimize resistance and resist arcing degradation.
Structural Characteristics:
Features a compact, space-saving design with a bolt-on or plug-in mounting configuration. Includes clear ON/OFF/TRIP indicator markings and a manual operating handle.
Working Principle:
Under normal conditions, it acts as a manual switch. During an overload, a bimetallic strip heats and bends to trip the mechanism. During a short circuit, an electromagnetic solenoid generates a magnetic field that instantly unlatches the contacts, breaking the circuit.
Installation Requirements:
Must be mounted in a properly rated electrical enclosure. Ensure adequate clearance for heat dissipation and torque all terminal connections to the manufacturer’s exact specifications.
Usage Precautions:
Always perform lockout/tagout (LOTO) procedures before servicing. Never exceed the rated voltage or current capacity. Regularly exercise the breaker to maintain mechanical reliability.
