By far, the largest number of C&T Shunts purchased are conventional clamp-type shunts. We manufacture these kinds of shunts, but with many variations available; variations that address railroad signaling needs such as additional resistance values, Open switch, wire lengths and colors, etc. The Open Switch can perform two functions: (1) literally Open the Shunt to allow a circuit to reset, trains to pass, etc. and (2) to create a “dirty” shunt to trigger a motion-responsive circuit by toggling the gold nut Open and Closed, or sliding a chrome-plated clamp along the rail..
ORDERING REFERENCES – CREATE YOUR OWN
Select resistance value or values: .06, .07, .10, .12,.15, .18, .20, .25, .30, .40, .50, 1.00, 1.10, 1.20, 1.30, 1.40, 1.50 and 2.0. Use “15X” for 1.50 ohm value and “2X” for 2.0 ohm value. Up to five resistances can be included in one Resistor Bracket. All test nuts down equals Zero ohm resistance.
Black (B) Wire Is furnished unless requested otherwise. Other choices are Red (R), Safety Orange (A) and Brite Yellow (Y). To specify color add alpha character in parenthesis (B, R, A and Y) in preceding listing to ordering reference as discussed below.
Add B (Base) or H (Head) to indicate Clamp preference.
Add Z to indicate Heavy Duty Shunt Carry Bag.
Typical Ordering Reference for a 2-Resistance (plus Zero) Shunt, Black Wire, Base Clamps with Carry Bag: 506-(_ _)(_ _)BBZ For Example: 506-(06)-(25)BBZ.
Additional resistances would be indicated by additional values in parenthesis, in series with those shown above. Note that the numbering of the “official” part number will vary from the sequence you provide us.
