Recommended Line Side Protection
The Bulletin 160 Smart Speed Controller has
been UL tested and approved for use with a fuse,
circuit breaker or manual motor starter installed
on the line side of the controller. The maximum
branch circuit protective rating is limited to four
times the rated output current of the drive or
30 amperes, whichever is less.
The ratings in Table 2.C and Table 2.D are the
“minimum” recommended values for use with
each drive rating. It should be noted that the
products listed under the column heading “Other
Protective Devices” must follow the proper
application guidelines stated for those products in
order to meet local or national electrical codes.
When using Bulletin 140 manual motor starters or
Bulletin 1492 circuit breakers the following
guidelines must be followed in order to meet the
NEC requirements for branch circuit protection:
Bulletin 140 manual motor starters can be used in
single and group motor applications. In single
motor applications, a fuse or UL489 rated circuit
breaker is required upstream from the Bulletin
140 manual motor starter. In group motor
installations, the Bulletin 140 can be used for
protection of an individual motor within the group
and “one set” of fuses or a UL489 rated circuit
breaker serves as the Short Circuit Protective
Device for the entire “Group Installation”.
Bulletin 1492 circuit breakers are rated as
supplementary protective devices. When using
this device, upstream fuses or UL489 rated circuit
breakers are required for each motor in the branch
circuit regardless if it is a single or group motor
installation.
