Marechal metal connectors and plugs provide high temperature distribution of power, signal and control circuits from 240°C to 400°C with 30A-90A rated power currents – contact us for support on specifying and ordering the correct Marechal connectors where high temperatures preclude use of standard plastic type plugs.
Applications for high temperature plugs include:
Marechal plugs withstand high temperatures and provide power supply to ovens and electromagnets in the steel industry – industrial power applications also include mobile cranes, cold rolling mills (DN20C) and motors on conveyors (DS3).
The Marechal PNHT and DSHT high temperature plugs, power connectors, signal and control connectors manufactured from metal provide excellent electrical connection quality in high temperature industries.

High Temperature Plugs For All Industries
What Are Autoclaves?
Autoclaves are strong heated containers used for chemical reactions and other processes using high temperatures and pressures.
Autoclaves are used throughout the worldwide thermal processing and bonding industries – this includes aerospace, military, composites, ballistics, glass and nuclear industries for vulcanizing, wood treatment and concrete curing. T&D can support the autoclave manufacturing industry with power plugs and connectors capable of withstanding heat and high temperatures up to 400°C.
The nuclear fuels industry uses autoclaves to prevent the accidental emission of gaseous UF6 (uranium hexafluoride) during feeding, delivery, and sampling operations.

In August 2006 ASC Process Systems (USA) announced it had built an autoclave with an internal volume of 2,321 m³ (82,000 ft³) – designed to process components of the Boeing 787 Dreamliner passenger aircraft by subjecting them to high temperatures of up to 232° C (450° F) and pressures of up to 10.2 bar.
Let’s try to disentangle terminology.
Marechal DO NOT manufacture plugs and sockets.
Well they do and they don’t. Let’s explain.
Their patented Decontactor is effectively a plug with a socket plus an integral load make/break switch. All in one.
Entirely electrically safe.
Marechal Decontactors require no “hard-wiring” like conventional or some may say “good old fashioned plugs”. See the anatomy of the Decontactor and give us a call to discuss your power requirements today.
