Yeah, I had used them . . . once. As they were a lower cost circuit breaker we spec'd them into a telecom system. What we didn't think about was the temperature extremes. For the higher temp tests for NEBS the higher temp breakers were too large and too expensive - for my management anyway.
I suppose they could serve a purpose during the fire spread test - power disconnection of chassis. Just a couple of thoughts . . . John A. Juhasz GE Interlogix Fiber Options Div. Bohemia, NY -----Original Message----- From: David Heald [mailto:[email protected]] Sent: Wednesday, August 07, 2002 11:18 AM To: 'EMC_PSTC' Subject: Thermal breakers vs magnetic breakers for telecom Greetings all, In the spirit of the continual quest for cost reduction, I have been asked to look into the use of thermal circuit breakers instead of magnetic ones. It seems like we rejected thermal breakers before for some reason, but now no one can remember why. Does anyone know of any telecom (or general) reasons why thermal circuit breakers may be unacceptable for telecom products?
