Insulated Red Standoff 30mm M8 Stainless Steel

An insulated hexagonal standoff, 30 mm tall with M8 threads, in red DMC composite with stainless steel inserts. Rated 660 V. Used to mount a high voltage component clear of the metalwork behind it.
Mounting a fuse or a busbar means holding it rigidly and insulating it at the same time. Bolt it straight to the enclosure and it is earthed. Sit it on a plastic spacer and the spacer creeps under bolt load until the joint is loose. A DMC standoff does both jobs properly: it is a structural insulator, dimensionally stable under load and at temperature, with metal threads that take real torque.
Red is the convention for a high voltage standoff, so anyone opening the enclosure can see at a glance what is isolated and what is not.

Features
- Structural insulator, so it holds a component rigidly instead of creeping under load
- Stainless steel M8 threads, which take real torque and do not corrode
- Rated 660 V, with red colouring marking it as a high voltage mount
- Hexagonal body, so it can be held with a spanner while tightening
Compatibility
For mounting high voltage components clear of surrounding metalwork: fuses, busbars, shunts and distribution blocks.
Check the 660 V rating against your pack. It covers a 400 V class system comfortably. An 800 V system needs a higher rated standoff.
Creepage and clearance are set by the installation, not by the standoff. Thirty millimetres of height does not on its own guarantee the separation your design needs. Consider the whole path, including across the surface of the standoff and any contamination that may settle on it.
