Altech Busbar Systems The Altech Busbar system is an innovative way to jumper up to 57 poles of Altech Miniature Circuit Breakers (MCB)/ Manual Motor Controllers (MMC), Supplementary Protectors (SP). Without Busbar Altech Busbar Systems The advantages of this jumper system are: • UL recognized and listed for Altech’s R Series, V-EA Series and MA Series of Miniature Circuit Breakers • Installation time savings • Panel space savings • Less or no maintenance • High electrical ratings • Customers can cut the busbar without losing the UL approval • UL recognized for use with a few competitor’s UL1077 supplementary protectors. Contact Altech for further information.
