Selecting Heavy Duty or Standard Duty RC5 Application
The RC5 overload rating has the capability of 150% braking torque for 30 seconds and 200% peak braking torque. The overload capability is based
on the standard duty rating. The RC5 overload rating can be applied to heavy duty applications. The following is a description of the heavy duty and
standard duty ratings.
■ Heavy Duty
Heavy duty applications require continuous energy dissipation (100% braking torque).
The overload rating is 125% for 60 seconds with a duty cycle of 25%. Braking torque of 187.5% is available for 30 seconds. Please note the peak
torque should be less than 250%.
The RC5 requires selecting Power Coordination and Current Suppression reactors according to specifications in Table 3.3 .
■ Standard Duty
Standard duty applications require intermittent full energy dissipation. The continuous rating is 80% or less braking torque and 100% braking torque
for 60 seconds with a duty cycle of 25% (60 seconds maximum on-time of every 240 seconds). The overload rating is 150% braking torque for 30
seconds. Please note the peak torque should be less than 200%.
The RC5 requires selecting Power Coordination and Current Suppression reactors according to specifications in
Table 3.3
◆ Main Circuit Input Fuse
■ Fuse Kits
The Fuse Kit is sized for both Heavy Duty and Standard Duty applications.
Connect a fuse at the primary side of the power suppression reactor. Recommended fuses are shown in Table 3.1 and Table 3.2 .
