STP230P05M

Overview

The STP230P05M is a Surge-Trap Pluggable Surge Protective Device (SPD) manufactured by Mersen USA Newburyport-MA L.L.C. It utilizes TPMOV® technology to provide fail-safe, self-protected surge suppression without requiring internal fuses. The device features DIN-rail mountable construction for easy installation in electrical panels. It is designed for line-to-neutral protection with a Maximum Continuous Operating Voltage (MCOV) of 275V and a nominal discharge current capacity of 50kA.

Feature Summary

• Fail-safe, self-protected design utilizing TPMOV® technology
• Pluggable form factor compatible with DIN-rail mounting systems
• No-fuse operation for simplified maintenance and replacement

Applications

• Line-to-neutral surge protection in electrical distribution panels
• Industrial control system circuit protection
• Commercial building electrical infrastructure safeguarding

Procurement Notes

Verify the specific voltage rating requirements against the application's maximum continuous operating voltage. Confirm that the DIN-rail mounting configuration matches the existing panel layout. Ensure the 50kA nominal discharge current capacity meets the local lightning and surge protection standards for the intended installation site.

Selection Notes

Select this component when a plug-and-play surge protection solution is required for single-phase circuits. The pluggable design allows for rapid replacement during maintenance without rewiring. Verify compatibility with the specific SPD holder or base unit if not integrated into the final assembly.

Part Context

This model belongs to the Surge-Trap STP-50 Series from Mersen. The series focuses on providing robust transient voltage suppression using proprietary metal oxide varistor technology. It serves as a critical component in protecting sensitive electronic equipment from voltage spikes caused by lightning or switching events.

Replacement Considerations

Ensure any substitute device maintains the same 275V MCOV and 50kA discharge current rating. Verify physical dimensions for DIN-rail compatibility and terminal configuration. Confirm the substitute also offers a fail-safe, no-fuse design to match the original safety profile.
