c3controls’ users do not need to identify and size additional short circuit protective
devices. Rather, these are determined by the self-protected combination motor
controller. As a result, customers who purchase Type E/Type F devices will recognize
simpler bills of materials, reduced inventory requirements, and lower overall costs.
The lock-off features of these devices ensure safety during maintenance and repair.
The trip indicator allows a user to determine which type of fault has occurred, whether
overload or short circuit, to ensure timely resolutions and minimal operational
downtime. Additionally, since the Type E device is self-protected, equipment does not
need to be replaced once a fault occurrence has been resolved.
