Brochures and Data Sheets

*Note: These are all congured for 3 phase, so there is no voltage code for 120V or 277V.
1. Modularity/expandability: a 337 may be added later to a 336 system, provided the power distribution bus, if any, is done correctly. Be sure to match
options! If 336 has 160PM or 160PS, be sure to order the same options for the 337.
2. Amp Rating is either the sum of generator rated currents rounded up to the next available rating size or equal to or less than the largest generator.
Example: two 600A gensets will use a 1200 Amp Rating. Larger generators may be possible, please consult factory. Amp Rating automatically selects
frame size in a cumulative conguration CT ratio.
336 Amp Ratings
336 Dimensions
Accessories specific for 300 series products all start with 160:
160PM: Power Management includes: (On 4 gen systems, must be ordered on both 336 and 337 to work properly.)
— 4 levels of Load Management (Load Shed/Load Add), Priority 1 never sheds. Priority 2, 3, 4 loads
are managed via ASCO option 30A in load ATS’s.
— Bus Optimization (Gen Shed/Gen Add).
— Start Next Gen on Alarm.
— Run Time Management or Run Time Equalization.
160PS: Isolated power supplies are required for installations where the generators’ DC systems have dissimilar
grounding schemes and recommended for all installations. Consult product information for more details.
Must be ordered on both 336 and 337 products for proper operation.
160DS: Dissimilar Sized Gensets. Standard conguration is with 2 generators of the same size; order this option if the
installation has 2 different sized generators. Sums of the currents must be below the Amp Rating. Specify gen sizes
in notes.
160CD: Custom Drawings. Generic drawings are standard. For custom or “as installed” drawings, purchase this option.
161TD1: Color HMI. A 7” color touchscreen, the ASCO TDI. 1 HMI per 336. 1 HMI per 337. Preloaded with ASCO
standard screens. Each HMI will display the data for the 2 gens in that section/on that CTTS. Includes a 72EE as an
Ethernet switch. Consult product information for more details.
160LU: For special lugs
Cabling access:
1200A and below: Standard is front access for connections, optional rear access.
1201A and above is always rear access.
Optional Output Distribution breakers or Load Panel(s) requests are custom engineered and quoted for the
specic project with UL891 switchgear with either UL489 or UL1066 style breakers. Contact 800-800-ASCO or
E-mail [e-mail] for technical questions, delivery times, and pricing.
