Technical Principles and Innovative Values
Advanced Trip Technology:The CR453CE2HBButilizes a precision thermal-magnetic trip mechanism with bimetal elements for overload protection and solenoid-actuated magnetic trips for short-circuit protection.The thermal element provides inverse-time delay characteristics matching cable and equipment damage curves,while the magnetic element ensures instantaneous operation during high-magnitude faults.
Robust Construction:High-strength molded housing with arc-resistant thermoset material provides excellent dielectric strength and mechanical durability.The CR453CE2HBB’s arc chute design with splitter plates effectively extinguishes arcs,while silver-alloy contacts ensure low contact resistance and long electrical life.
Safety Features:Positive mechanism prevents contact welding,and the quick-make/quick-break action ensures reliable operation under fault conditions.The CR453CE2HBB’s visible blade position indicator and trip status provide clear operational feedback,while the sturdy operating handle allows safe manual operation under load.
Application Cases and Industry Value
In a large manufacturing facility’s motor control center upgrade,the GE CR453CE2HBBcircuit breakers were implemented to replace aging breakers that lacked adequate interrupting capacity.The new installation provided coordinated protection for 400HP motors,with the CR453CE2HBB’s precise time-current characteristics preventing nuisance trips during motor starting while ensuring fast fault clearance.The project resulted in a 60%reduction in unexplained trips and improved production continuity,with estimated savings of$500,000 annually in prevented downtime.The breakers’reliable performance also reduced maintenance costs by 40%compared to the previous electromechanical protection system.
A water treatment plant utilized the CR453CE2HBBfor their high-capacity pump motor protection,where the breakers’corrosion-resistant construction withstood the humid environment.The thermal-magnetic protection provided optimal coordination with motor overload relays,preventing single-phasing damage that previously cost$75,000 per motor replacement.
