 +===== Replacement ===== 
 +The 1140 is no longer available from Ten-Tec. ​ Ten-Tec recommends an [[http://​www.airpax.net/​|Airpax]] T-11 20 amp fast acting breaker [[http://​airpax.sensata.com/​pdfs/​snapak.pdf|(Catalog)]]. Airpax part number is T11-1-20.0A-01-10A-V 
 + 
 +**Additional Information from the Ten-Tec Reflector July 7, 2000** 
 + 
 +Those breakers were made for Ten-Tec by Airpax. ​ Airpax still makes dozens of breakers........ the series mfg for Ten-Tec is the Snapak model magnetic breaker. 
 + 
 +Airpax breaker part number should be: 
 + 
 +T11-1-(required amperage 3 places)-01-10A-V 
 + 
 +example: ​ T11-1-5.00A-01-10A-V 
 + 
 +  * T11 = Paddle Handle, Single Pole, Series Breaker 
 +  * 1 = "​fast"​ trip (0 =instant and 2 = slow...... 2 is too slow 0 would work fine too) 
 +  * 5.00A = 5 amp 
 +  * 01 = Paddle Handle is Black 
 +  * 10A = Black Knurled Mounting Nut 
 +  * V = Vertical Mount 
 + 
 +Enter in the original amperage of the breaker you are looking for and this number should be close if not right on to the original...... Ten-Tec'​s Paul Clinton told me awhile ago that either the fast or instant breaker would work fine..... I've 
 +seen the breakers they sold for the Triton IV and some were fast and some were instant anyway. 
 + 
 +Best place to find them (they are hard to find) at the best price ($25 min order - Airpax has a $500 minimum) I've found is: http://​www.pocosales.com/​
