Carling, symmetrical alarm
breakers**
*Amphenol Network Solutions suggests avoiding use of different types
of circuit breakers in the same load center. Alarm contacts may vary
among interrupter manufacturers and may incapacitate the alarm
system
**Circuit breakers for this load center are designed and manufactured
by Airpax Corporation and Carling Industries to meet the Amphenol
Network Solutions symmetrical pin specifications. Order circuit
breakers only from Amphenol Network Solutions
