Telect can only guarantee circuit breakers that our purchased from Telect for use in our power distribution panels. For example, Telect uses either an REC4, or RLS4 breaker type in the 600CB08 due to the channel mesh design for connectivity to aux switches. However, due to the alarming circuitry being designed for the specific operation of each panel putting non-Telect circuit breakers into the panels can cause unexpected alarming behavior. |
