Features
Typical Specifications
1. Approvals
A. The Fire Pump Controller shall meet the require-
ments of the latest edition of NFPA 20 and shall be
listed by [Underwriters Laboratories (UL)]and ap-
proved by [Factory Mutual Research (FM)] [Cana-
dian Standards Association (CSA)] [New York De-
partment of Buildings (NYSB)] and carry the CE
marking for fire pump service.
2. Starting
Type
A. The controller shall be of the combined manual and
automatic type designed for [Full Voltage Starting]
[Part Winding Starting] [Primary Resistor Starting]
[Autotransformer Starting] [Wye-Delta (Star-Delta)
Open Transition Starting] [Wye-Delta (Star-Delta)
Closed Transition Starting] [Solid State Soft Start
Starting]
3. Ratings
A. The Controller shall have a withstand rating of
100,000 RMS symmetrical amperes @ [208V] [240V]
[380V] [400V] [415V] [480V] [25,000 @ 600VAC].
4. Construction
A. The controller shall include a motor rated combina-
tion isolating switch and circuit breaker, mechanically
interlocked and operated with a single externally
mounted handle.
B. The isolating switch shall be rated to disconnect the
motor load.
C. The isolating switch/circuit breaker combination shall
be mechanically interlocked such that the enclosure
door cannot be opened when the handle is in the on
position except by a tool operated defeater mechan-
ism.
D. The
controller
manufacturer shall manufacture the
contactor, isolating switch, circuit breaker, pushbut-
tons, and enclosures. Brand-labeled components
will not be accepted.
5.
Enclosure
A. The controller shall be housed in a NEMA Type 2
(IEC IP11) drip-proof, powder baked finish, frees-
tanding enclosure.
B. Optional
Enclosures:
1. NEMA 3R (IEC IP14) rain-tight enclosure.
