Current ratings

Multiple resistance bank mounting frame is a sheet steel frame, sturdy in construction with welded top and bottom plates

having corrosion resistant finish. They are available in different sizes to accommodate from 3 to 6 resistor banks and can

be used with the WL bank. These mounting frames can be installed back to back and side by side and have provision for

bolting to floor. Resistor bank can be stacked within the mounting frame and can be drawn out from the front quite easily,

without disturbing the end plates.

Sheet steel enclosures of IP-11 and IP-33 as per IS-2147 are available for stacked assemblies with adequate ventilation.

IP-11 type enclosures are also available for back to back arrangement.

Dimensions of the enclosures are as given below. Figure 1 gives the overall dimensional drawing for Punched grid

resistor panel WL with integral terminal arrangement enclosure type IP 33 for single column & double column.

Table I give continuous current rating, type of terminals, resistance per bank & resistance per tap, and total number of

taps, based on NEMA requirements Table II & III gives the intermittent duty rating of WL type grids.
