Busbars
UL1077/508 Busbar System (1)
• Electrical Rating: 80A@480VAC (18mm² Pins), 100A@480VAC (25mm² Pins)
• 1,2,3 Phase
• Any possible Pin configuration (1-57Pins)
• ½ pole spacing (auxiliary switch) available
• Power feeding: Power Feed Lugs (115A), Direct Power Feed (80A), Power Feed Block (200A)
• UL508 listed
Busbars
UL1077/508 Busbar System (2)
• Busbars can be cut to customers needs without loosing UL-approval
• UL recognized and listed for Altech’s R-Series, V-EA Series and MA Series of Manual Motor Controllers and Supplementary Protectors
• UL recognized and listed for use with most competitor’s UL1077 supplementary protectors and UL508 Manual Motor Controllers
Busbars
UL489 Busbar System (1)
• Electrical Rating: 80A@480VAC (16mm² Pins)
• 1,2,3 Phase
• 6, 12, 18 Pin configuration
• Power feeding: Power Feed Lugs (115A), Direct Power Feed (80A)
• UL489 listed
Busbars
UL489 Busbar System (2)
• Every Pin configuration possible by combination of existing 6, 12 and 18 Pin Busbars
• UL listed for Altech’s L-Series of Miniature Molded Case Circuit Breaker
• UL listed for use with most competitor’s UL489 Miniature Molded Case Circuit Breaker
Busbars
Configuration of UL489 Busbars (1)
• UL489 Busbars are available in 3 different Pin Configurations per Phase (6, 12 and 18 Pins)
• They can’t be cut, since the creapage and clearance distance requirements from UL are too stringent.
• Therefore to obtain the desired No. of Pins, Busbars can and must be overlapped
Busbars
Configuration of UL489 Busbars (2)1) Busbars are overlapped backwards to each other
Configuration Examples:
1 Phase Busbars 3 Phase Busbars
Busbars
Configuration of UL489 Busbars (3)1) Busbars are overlapped backwards to each other
2) The Number of overlapping Pins of 2 Busbar must be a multiplier of the Number of Phases to keep existing Phase sequence. (Can be overlapped by more than the number of phases)
Configuration Examples:
1 Phase Busbars 3 Phase Busbars
Busbars
Configuration of UL489 Busbars (4)1) Busbars are overlapped backwards to each other
2) The Number of overlapping Pins of 2 Busbar must be a multiplier of the Number of Phases to keep existing Phase sequence. (Can be overlapped by more than the number of phases)
3) Any available combination of the 3 different Pin configurations is possible
Configuration Examples:
1 Phase Busbars 3 Phase Busbars
