3P 1000A Rating Molded Case Circuit Breaker

In the energy heart of modern large-scale facilities - the main distribution room, 1000A current marks one of the highest capacity levels for power distribution. SPX is deployed in this high-quality 3P 1000A Rating Molded Case Circuit Breaker, which has surpassed the scope of traditional protective appliances and evolved into a comprehensive power management platform that integrates strong current control, weak current logic, and digital communication.

Features:

Rated current of 1000A, it can safely carry sustained power loads of approximately 550kW (400V three-phase) or more, meeting the power convergence needs of large data center rooms, heavy-duty production lines, or entire buildings.
The 3P 1000A Rating Molded Case Circuit Breaker provides industry-leading extreme short-circuit breaking capabilities of up to 120kA-150kA, capable of withstanding and safely clearing the most destructive short-circuit faults that may occur. It is the last solid line of defense to ensure the physical architecture of the entire low-voltage distribution system does not collapse.
Adopting a specially designed high-strength insulation frame and optimized heat dissipation duct design, it ensures excellent dynamic thermal stability and low operating temperature rise during long-term high current operation and high breaking process.
Equipped with the most advanced multifunctional digital trip unit, it provides a comprehensive and programmable protection matrix including overload, short-circuit short delay, short-circuit instantaneous, ground fault, residual current, etc. The protection setting can be accurately set within a wide range and flexibly combined with time characteristics.
The precise short delay protection function of 3P 1000A Rating Molded Case Circuit Breaker is the key to achieving fully selective protection from this level to the end circuit breaker, ensuring that faults are maximally limited to the minimum range and guaranteeing uninterrupted operation of the rest of the system.
Equipped with powerful fault recording, event recording, temperature monitoring, and health diagnosis functions, it can provide early warning of potential risks and achieve a transition from "post protection" to "pre prevention".
Real time collection and display of all electrical parameters, including current, voltage, power, energy, power factor, frequency, harmonic content, demand, etc., is the core data source for building a digital distribution system.
Native support or advanced module support for protocols such as Ethernet, Profinet, Modbus TCP/IP, and even IEC 61850, seamlessly integrated into factory level energy management systems, building automation systems, or cloud based IoT platforms.

Application

High quality 3P 1000A Rating Molded Case Circuit Breaker serves as the low-voltage main incoming circuit breaker for each power supply module (such as the entire data center layer) to protect critical IT loads.
Low voltage bus protection and sectionalizing switches for large-scale refining, semiconductor chip factories, and automotive manufacturing main buildings.
Transformer low-voltage side main switch for super high-rise buildings, large international airport terminals, and giant sports venues.
The core power distribution protection for the main power supply and distribution of tertiary hospitals, subway main substations, and large-scale water treatment centers.
AC low-voltage side collection circuit breakers for hundred megawatt level photovoltaic power stations or energy storage power stations.
