Description
GE FBN36TE070RV
Technical Specifications
- Pole Configuration: 3-Pole design for three-phase power systems.
- Rated Current: 70 Amps continuous operating current.
- Rated Voltage: 600 VAC maximum system voltage.
- Product Series: FBN series molded case circuit breaker.
Functional Features
- Overcurrent Protection: Designed to automatically interrupt electrical flow during short circuits or overload conditions to prevent equipment damage and fire hazards.
- High-Voltage Isolation: Rated for 600 VAC applications, making it suitable for industrial power distribution networks.
- Thermal-Magnetic Trip Mechanism: Provides dual protection against both prolonged overloads (thermal) and sudden short circuits (magnetic).
Application Scenarios
Widely deployed in heavy industrial manufacturing plants, commercial power distribution panels, and large-scale infrastructure electrical systems requiring robust 600VAC protection.
Performance Parameters
- Continuous Current Rating: 70 Amps.
- Maximum System Voltage: 600 Volts AC.
- Interrupting Capacity: Designed to safely clear high-energy fault currents at 600VAC.
Material Composition
The housing is constructed from high-strength, flame-retardant thermoset plastic. Internal contacts utilize high-conductivity silver-alloy materials designed to withstand extreme arcing temperatures during fault interruption.
Structural Characteristics
Features a standard molded case design with a compact footprint for efficient panel space utilization. It utilizes a toggle-style manual operator for clear visual indication of ON, OFF, and TRIPPED positions.
Working Principle
Under normal conditions, the breaker’s contacts remain closed, allowing current to flow. During an overload, a bimetallic strip heats up and bends to trip the mechanism. During a short circuit, an electromagnetic solenoid generates a magnetic field that instantly forces the contacts open. The arc chute then cools and elongates the resulting electrical arc until it is safely extinguished.
Installation Requirements
Must be installed in a compatible GE panelboard or enclosure rated for 600VAC. Requires proper torque specifications for line and load terminal connections to prevent hot spots.
Usage Precautions
Always verify the system voltage and load current do not exceed the breaker’s 600VAC / 70A ratings. Strictly adhere to Lockout/Tagout (LOTO) procedures before installation or maintenance.
