Page 7: Circuit Breaker Racking Interlock (Screw Type)
Vehicle Description Circuit Breaker Racking Interlock (Screw Type) Reference: Figure 1 The racking interlock functions to maintain the circuit breaker mechanism in a “trip free” state whenever the cir- cuit breaker is “released”. • The circuit breaker is closed whenever the primary cir- cuit is completed through the vacuum interrupter con- tacts. -
Page 8: Plunger Position Mechanical Interlock
Vehicle Description As the push rod rises, its “mushroom” headed append- age, within the circuit breaker mechanism enclosure, causes the “interlock” levers to rotate, elevating the “trip free push rod and cam”. This cam encounters the “trip latch lever”, and after typically 8 to 12mm (0.3 to 0.5 inches) of motion forces the mechanism, through the “trip latch lever”, and coupled “trip latch”... - Page 9 Vehicle Description Figure 4. 1200, 2000, and 3000 Amp Continuous Current Interlock Orientation Plunger Position Mechanical Interlock Switch Figure 5.
