7-1618413-2

Overview

The TE Connectivity Aerospace, Defense and Marine part number 7-1618413-2 is a general-purpose DC contactor belonging to the EV500 series. It features an SPST-NO (DM) single-pole normally-open contact configuration with a high current rating of 1 kA. The device utilizes a 24 VDC coil voltage and is designed for chassis mounting. Key electrical specifications include a coil resistance of 72 Ohms, an operate time of 20 ms, and a release time of 5 ms. The contact material is specified as copper.

Feature Summary

• High-current switching capability rated at 1 kA for demanding DC applications
• Dual Magnetic (DM) arc suppression technology integrated into the contact design
• Chassis mount construction providing secure mechanical installation stability

Applications

• Industrial DC power distribution systems requiring high current interruption
• Electrical control circuits in defense and marine environments
• Heavy-duty motor control and load switching applications

Procurement Notes

Verify the specific coil voltage requirement matches the system design, as variants exist within the series. Confirm that the chassis mounting style aligns with the available panel or enclosure space. Ensure the 1 kA current rating exceeds the maximum expected load current to maintain operational safety and longevity under continuous duty conditions.

Selection Notes

Select this component when a robust, high-amperage DC contactor is required for industrial or aerospace use. The dual magnetic arc suppression feature makes it suitable for breaking high inductive loads efficiently. Consider the chassis mount form factor if space constraints preclude socket-based installations. Verify compatibility with the 24 VDC control signal source before finalizing the design integration.

Part Context

This contactor is part of the EV500 series from TE Connectivity Aerospace, Defense and Marine, which specializes in rugged electromechanical components. The series is engineered for reliability in harsh environments, including those found in military, aerospace, and marine sectors. The EV500 line provides various current ratings and coil voltages to meet diverse high-power switching requirements across critical infrastructure applications.

Replacement Considerations

Cross-reference with other EV500 series parts for alternative coil voltages or current ratings. Verify mechanical footprint compatibility if substituting with similar chassis-mount contactors from different manufacturers.
