MDC 55 JUMPER SWITCH SAFETY

Developed with the professional sector of petrochemicals, the ergonomics of our switches is reviewed to ensure optimal security operators in workshops. Their small size allows easy access to the cell and the control box offset to a short-circuit protected from any projections.

 

MDC 55 JUMPER SWITCH ERGONOMY

Thanks to ergonomics of our switches, our machines have a very clear and simple utilization :

• The low weight and compactness allow a precise and rapid implement on place
• User security : our systems provide enough space to work safely between cell and jumper switch
• Presence of storage rack for pipes and bolts.
• Easy to install as our systems only need water and air connections.
• Easy maintenance.

MDC 55 JUMPER SWITCH ECONOMY

Using protection by arcing contacts protects the contacts from electric arcs provoked by current cuts.
