Product FAQs
6 answersWhat types of systems is the Airpax JTEP-3-1REC4-30751-7 designed to protect?
This 750A DC circuit breaker is engineered specifically for telecommunications equipment and power distribution units (PDUs) requiring robust, high-amperage DC overcurrent protection.
How does the hydraulic-magnetic trip mechanism in the JTEP-3-1REC4-30751-7 operate?
The hydraulic-magnetic design provides fixed Long-Time and Instantaneous (LI) trip functions that remain stable across temperature variations. This ensures accurate tripping without the nuisance tripping often caused by ambient heat in densely packed telecom panels.
What are the physical connection points for installing the JTEP-3-1REC4-30751-7?
This breaker is designed for panel mounting and uses stud or tapped pad terminals, allowing for secure, high-torque connections necessary for safely handling 750A DC loads.
How does the JTEP-3-1REC4-30751-7 achieve its 750A rating across three poles?
This breaker utilizes a parallel pole construction. The three poles work together in parallel to safely carry and distribute the high 750A DC load, which is a standard configuration for high-amperage telecom breakers.
What does the 1REC4 designation in the JTEP-3-1REC4-30751-7 part number indicate?
The 1REC4 catalog prefix signifies that the breaker is equipped with a factory-installed auxiliary switch, which allows for remote status indication and integration into facility monitoring systems.
Can the JTEP-3-1REC4-30751-7 handle high fault currents in DC systems?
Yes, it is rated for a 100kA interrupting capacity at 65V DC, making it suitable for telecom applications with high available fault currents. It can also safely interrupt up to 10kA at 160V DC.
