UL 489 Listed 240 Vac C60 Circuit Breakers (AC)
A selected range of Multi-9 circuit breakers rated 240 V are UL 489 Listed. Unlike UL 1077
Supplementary Protectors, these UL 489 circuit breakers can be used for branch circuit protection as
required by the National Electrical Code.
As shown in tables Table 5 and Table 6, the UL 489 Listed products are available in C and D curves.
They include devices ranging from 0.5 to 35 A.
Standard Features
•
Fast closing: Allows increased withstand to the high inrush currents of some loads.
• Trip-free mechanism: Contacts cannot be held in the I-ON position when the C60 circuit breaker is
tripped automatically.
• Positive indication of contact disconnect. Green mechanical indication on front face of circuit
breaker shows that all poles are open.
• C curve: Overcurrent protection for all application types. Magnetic release operates from 7 to 10
times ampere rating (7 to 14 for DC applications).
