HERE'S A HERMETICALLY-SEALED CIRCUIT BREAKER The Heinemann Series SM is a subminiature breaker that will probably land on the moon in a U.S. manned capsule. Its hermetic seal makes the SM suitable for a number of earth-bound hazardous environmental appli cations as well: hospital operating rooms, petro-chem plants, graneries, aircraft facilities, and bulk oil termi nals to name some. If you need overcurrent protection in a hazardous area, get all the facts on the SM. They're in Bulletin 3504.
