1616056-1

Overview

The TE Connectivity 1616056-1 is a general-purpose DC relay from the Ariat series, rated for 400 amperes. It features a single-pole single-throw normally open (SPST-NO) contact configuration designed for high-current switching applications. The component utilizes a coil voltage of 12 volts DC to actuate the contacts. Constructed for durability in demanding environments, it operates within a temperature range of -40°C to +85°C. The unit employs a base-mounted installation style with stud terminals for secure electrical connections.

Feature Summary

• High current capacity rated at 400 amperes for DC circuits
• Single-pole single-throw normally open contact architecture
• Base-mounted design compatible with standard relay sockets
• Operational stability across extreme temperature ranges

Applications

• Industrial motor control systems
• Power distribution management units
• Heavy-duty vehicle electrical architectures
• Marine propulsion control interfaces

Procurement Notes

Verify the specific coil voltage and contact configuration against system requirements before procurement. Confirm environmental ratings match operational conditions. Check RoHS compliance status as historical data indicates non-compliance for this part number. Ensure mounting hardware compatibility with the base-mount design. Validate lead-free status if required by project specifications.

Selection Notes

Select this component when high-amperage DC switching is required in space-constrained industrial or vehicular applications. The Ariat series offers robust performance for heavy loads. Consider the 12V DC coil requirement for driver circuit compatibility. Evaluate thermal management needs given the high current rating. Compare against alternative series if lower current or different form factors are sufficient.

Part Context

This relay belongs to the Ariat product line manufactured by TE Connectivity Aerospace, Defense and Marine. The series is engineered for rugged environments requiring reliable high-current switching. The 1616056-1 variant specifically addresses applications needing 400A DC capacity. It complements other components in power management systems where mechanical reliability under stress is critical.

Replacement Considerations

Consult official TE Connectivity documentation for direct cross-references. Verify pinout and dimensional compatibility before substituting. Ensure replacement parts meet the same 400A DC rating and 12V coil specification. Check for updated RoHS compliance in newer revisions.
