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: (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 Busbars3 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 Busbars3 Phase Busbars
