Redefining Paralleling Systems.
Since introducing the rst power transfer switch in 1920,
ASCO has been committed to providing reliable technology,
superior support and dedicated eld service to satisfy power
switching and controls requirements for critical operations.
Throughout the more than 90 years of power transfer tech-
nology development, ASCO has introduced every signicant
product innovation in the industry.
That leadership and commitment to innovation continues
with the 336 Paralleling System. Incorporating eld-proven,
reliable technology in a patented dual operator transfer
switch mechanism, the 336 Paralleling System meets the
needs of design build projects: cost effective, reliability,
and quick delivery.
The 336 Paralleling System, available from 208 to 600
Volts, is the rst transfer switch-based paralleling system
on the market. It combines robust UL approved components
in a standardized design that brings added exibility,
reliability, and cost savings to any project.
A Superior Choice
Revolutionary CTTS-based design High reliability and endurance
Utilizes generator power for switching Eliminates costly and maintenance-prone, lead-acid batteries
Exclusive load management feature Maximum protection of priority one loads
Handles all generator grounding congurations Generators with different DC grounded schemes can be paralleled safely
Compact modular design Minimal conguration eliminates job-specic engineering; easy to expand
Simple operation Entire system starts with single contact or door control switch

Power transfer at your fingertips.
At the core of the 336 Paralleling System is a eld
proven closed transition transfer switch (CTTS). This is
a highly reliable mechanism that studies have shown
to have more endurance life than competitive products.
Incorporating advanced components into the 336
Paralleling System help make it a superior alternative to
conventional circuit breaker-based systems.
Using AC power from the generators to switch the
CTTS with the latest control system technology,
the 336 Paralleling System can detect and recover
accordingly from common problems and
automatically start the next generator in the system.
This design technique eliminates the need for costly
and maintenance-prone lead-acid batteries often
found in conventional switchgear systems.
