Shown above is design of heavy duty transfer switches from 104 amps -1200 amps in NEMA-1 enclosure.  NEMA-3R enclosures for outdoor installation is also available.  The included microprocessor performs many automatic engine functions and control procedures.

OPERATION

These heavy duty SERIES 300, industrial/commercial rated ATS systems includes suitable voltage sensing circuitry for automatic transfer of an "all class" electric load, to an emergency power, standby generator set, in the event of a drop or total loss of utility power.  Upon restoration of utility power, the electric load is automatically re-transferred back to utility power.

ASCO SERIES 300 HEAVY DUTY
AUTOMATIC TRANSFER SWITCH FEATURES

• 30 AMPS TO 1200 AMPS in compact design.

• AVAILABLE TO 600 VOLTS IN SINGLE OR THREE PHASE.

• TRUE DOUBLE-THROW, INHERENTLY INTERLOCKED CONSTRUCTION (NO INTENTIONAL OFF POSITION). 

• MECHANICALLY HELD - ELECTRICALLY OPERATED USING THE PROVEN DESIGN OF A SINGLE SOLENOID OPERATOR.  THIS DESIGN ELIMINATES ELECTRIC VIBRATION NOISE ON SOLENOID OPERATING POSITION.

• CONTACTS ACCESSIBLE FOR EASY INSPECTION AND PREVENTIVE MAINTENANCE.

• SUPPLIED WITH SOLID NEUTRAL TERMINATION.

• UL1008 LISTED FOR TOTAL SYSTEMS LOADS (INCLUDING INDUCTION MOTOR LOADS).

• MEETS NATIONAL ELECTRICAL CODE ARTICLES 700, 701, AND 702, PLUS CSA REQUIREMENTS.  GENERAL PURPOSE TYPE 1 (FOR INSIDE INSTALLATIONS) AND TYPE 3R (FOR OUTSIDE INSTALLATIONS) ARE AVAILABLE THROUGH 1600 AMPS.  NOTE ADD SUFFIX -3R TO ALL TRANSFER SWITCH MODELS FOR NEMA 3R ENCLOSURES.

• MANUAL TEST SWITCH.

• TIME DELAY BYPASS SWITCH.

• TIME DELAYS : ADJUSTABLE TIME DELAY TO OVERRIDE MOMENTARY NORMAL SOURCE OUTAGES; ADJUSTABLE TRANSFER DELAY TO EMERGENCY POWER; ADJUSTABLE RETRANSFER TO NORMAL UTILITY POWER; 5 MINUTE UNLOADED RUN TIME FOR ENGINE COOLDOWN.

• SWITCH POSITION LIGHTS.

• ADJUSTABLE CLOSE DIFFERENTIAL VOLTAGE SENSING ON ALL PHASES OF UTILITY POWER.  PICK-UP VOLTAGE IS ADJUSTABLE TO 95% OF NOMINAL VOLTAGE; DROP-OUT VOLTAGE IS ADJUSTABLE FROM 70% TO 90% OF NOMINAL VOLTAGE.

• SELECTIVE LOAD DISCONNECT WITH DOUBLE-THROW CONTACT TO RATE AT AN ADJUSTABLE 0-20 SECOND TIME DELAY PRIOR TO TRANSFER AND RESET 0-20 SECONDS AFTER TRANSFER.

• IN PHASE MONITOR TO TRANSFER MOTOR LOADS WITHOUT ANY INTENTIONAL OFF TIME, TO PREVENT IN RUSH CURRENTS FROM EXCEEDING NORMAL STARTING LEVELS.

• ENGINE EXERCISOR TO AUTOMATICALLY TEST ENGINE EACH WEEK.  THIS INCLUDES CONTROL SWITCH TO TEST WITH OR WITHOUT LOAD.

Dimensions and Shipping Weights
UL Type 1 Enclosure (See notes below for information on Type 3R, 4 & 12 Enclosures)

Notes:   

1.  For Type 3R, 4 & 12 dimensions, add the following values to the Type 1 dimensions:
        a)  104, 150, 200a - add 1.5 in. (38 mm) to the height.
        b)  1000-1600A - add 3 in. (76 mm) to the height and 10 in. (253 mm) to the width.
2.  For Type 3R, 4 & 12 weights, add the following values to the Type 1 weights:
        a)  104, 150, 200A - add 15 lbs. (6 kg).
        b)  230, 260, 400A - add 30 lbs (14 kg).
        c)  600, 800A - add 42 lbs (19 kg).
        d)  1000-1600A - add 60 lbs (27 kg).
3.  When temperatures below 32°F can be experienced, special precautions should be taken, such as the inclusion of space heaters, to prevent condensation and freezing of this condensation.  This is particularly important when environmental enclosures (Type 3R, 4 & 12) are ordered for installation outdoors.
