Installing Bullet Nose Circuit Breakers and/or Fuseholders (with TPS/TPL 

Fuses) 

 

ALERT!  

For ambient temperatures at or below +40°C (+104°F), overcurrent devices rated 100A or greater MUST HAVE an 

empty mounting position between it and any other overcurrent protective device.  Maximum size circuit breakers that can be 
used are 100A single pole, 200A double pole, and 250A triple pole.  Maximum size fuse is 100A.  The distribution row is rated 
for a maximum of 250A. 
 
For ambient temperatures b40°C (+104°F) and +65°C (+149°F), overcurrent devices rated 60A or greater MUST 
HAVE an empty mounting position between it and any other overcurrent protective device.  Maximum size circuit breakers 
that can be used are 70A single pole.  No double pole or triple pole circuit breakers can be used.  Maximum fuse size is 70A.  
The distribution row is rated for a maximum of 250A. 

 

NOTE!

  

Circuit breakers and/or fuses may have been factory installed for you.  If so, verify their positions and sizes. 

 

Procedure 

1.

 

Open the shelf’s front door. 

2.

 

Circuit Breakers and Fuses: 

 Ensure that a circuit breaker is in the OFF position.  Orient the distribution device as shown in 

Figure 2.5.  Insert the terminals on the rear of the distribution device into their corresponding sockets on the distribution row.  
Ensure the alarm contact on the back of the distribution device makes contact with the alarm terminal on the mounting 
circuit card.  Push distribution device in firmly until fully seated in the distribution row. 

3.

 

Fuses: 

 When all fuseholders are installed, install an appropriately sized TPS/TLS fuse in each.  To do this, remove the fuse 

carrier from the mounted fuseholder body by pulling it straight out.  Slide the fuse in place between the contacts of the fuse 
carrier.  When done, push the fuse carrier back into the fuseholder body.  Note that a polarizing key on the bottom of the 
carrier prevents the carrier from being inserted upside down.  Verify that an 18/100 ampere alarm fuse is present in each 
fuseholder and that a plastic safety cover is installed on this fuse. 

4.

 

Record all circuit breaker and/or fuse sizes on the label provided. 

5.

 

Close the shelf's front door.
