Altech Busbar Systems

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).
Without Busbar
The advantages of this jumper system are:
• Installation time savings
• Panel space savings
• Less or no maintenance
• High electrical ratings
• Customers can cut the busbar
without losing the UL approval
