PUSH-IN BRACKET FORM A
For the assembly of resistors without pins. The retaining brackets are supplied loose.
To prevent rotation the resistors are also available slotted at one end upon request. Depending on the type, this reduces the
leakage path (creeping distance) to the clamp by 1.2 mm to 3.5 mm.

CERAMIC CENTERING DISCS (KER 221 DIN 40685)
To increase the leakage path (creeping distance) when assembling resistors with through-pin.
Ceramic centering discs can be supplied fully assembled with retaining brackets form B and resistors GWS 25 - GWS 30/133,
ZWS 12 - ZWS 30/133 which can be delivered completely mounted.
CENTERING DISCS (KER 110 DIN 40685)
The manufacture of centering discs for resistors of small inside diameter is not feasible. To increase the leakage path (creeping
distance) of these types, we supply ceramic discs, centered together with the resistors through the retaining pin.
