- Shock and vibration resistant
- Range of standard enclosures
- Specifically designed for motor control
Service grids are a robust flat plate style of resistor manufactured from 304 grade stainless steel elements insulated using mica and welded together to form a continuous low inductance resistance path. Service grid resistors can be supplied as either open banks or housed in ventilated enclosures.
Every grid has punched holes within the welded contact section to give intermediate tapping points.
There are two standard enclosure styles for service grid resistors; Industrial Housings for general purpose applications and System 22 Housings designed for steel mills, this allows the replacement of individual banks without disturbing other banks in the enclosure.
Either type of enclosure can be supplied as painted mild steel, hot dip galvanized to BS729 or natural finish grade 304 stainless steel.
