2000 Amp. Thomson Power, Automatic Transfer Switch, 1 or 3 phase, 208-600 Volts, New

Thomson TS 880 2000 Amp Automatic Transfer Switch – NEMA 3R Outdoor Enclosure

The Thomson Power Systems TS 880 Series 2000 Amp Automatic Transfer Switch is built for large commercial, industrial, and critical-power systems that require dependable transfer between utility and generator sources.

Designed for demanding standby and emergency applications, this ATS continuously monitors both available power sources and automatically transfers the connected load when utility power is lost or falls outside acceptable operating limits.

Once the generator reaches stable voltage and frequency, the switch transfers the load to emergency power. After the normal utility source returns and remains stable, the ATS automatically retransfers the load and allows the generator to complete its programmed cooldown sequence.

This unit is installed in a heavy-duty NEMA 3R double-door enclosure, providing outdoor environmental protection along with convenient front access for wiring, inspection, programming, and maintenance.

In stock and available for prompt shipment from Joval Industrial.

Heavy-Duty TS 880 Switching Design

The Thomson TS 880 platform uses two independently operated power-switching mechanisms that are mechanically interlocked to prevent both sources from being connected at the same time.

This design provides safe and reliable transfer between the normal and emergency supplies while protecting the electrical system against source overlap and backfeeding.

The enclosed switching components and silver-alloy contacts are designed to support long service life, dependable operation, and consistent performance under high-current conditions.

Key switching benefits include:

• Positive mechanical source interlocking
• Reliable operation under full rated load
• Reduced exposure of power contacts
• Strong resistance to contact wear
• High fault-current withstand performance
• Consistent transfer operation in critical applications

Open-Transition Operation

This ATS uses an open-transition, break-before-make transfer sequence.

During a power transfer, the connected load is first disconnected from the active source before being connected to the alternate source. The utility and generator supplies are never intentionally connected together.

This operating method helps:

• Prevent utility-to-generator backfeeding
• Protect connected equipment
• Avoid unintended source paralleling
• Maintain proper electrical-system isolation
• Provide a simple and dependable transfer sequence

TSC 7320 Advanced Controller

The included TSC 7320 controller provides automatic control, system monitoring, programmable timing, and operating-status information from the front of the enclosure.

The controller monitors the utility and generator sources and determines when engine starting, transfer, retransfer, cooldown, and shutdown commands should occur.

Controller functions may include:

• Real-time voltage monitoring
• Utility and generator frequency monitoring
• Three-phase source sensing
• Engine-start delay
• Generator warm-up timing
• Transfer delay
• Retransfer delay
• Generator cooldown timing
• System-status display
• Alarm indication
• Power-failure event history
• Transfer-event logging
• Generator runtime tracking
• Load-disconnect functions
• Load-shed control capability
• Programmable operating limits

Available communication options may include Modbus through RS485 or TCP/IP, depending on the installed factory options and exact switch configuration.

Operating settings can be accessed from the front controller interface, helping reduce the need to open energized equipment sections for routine adjustments.

NEMA 3R Double-Door Enclosure

The ATS is housed in a durable double-door enclosure designed for indoor or outdoor power-system installations.

The divided front-access design improves access to internal components while helping separate control areas from high-current switching and termination sections.

Enclosure benefits include:

• NEMA 3R outdoor-rated construction
• Protection against rain and sleet
• Heavy-duty industrial steel cabinet
• Double-door front access
• Easier access to controls and power sections
• Padlock provisions for controlled entry
• Improved service and inspection access
• Convenient cable-termination access
• Suitable for demanding industrial environments
• Reduced unnecessary exposure to energized components

Source Monitoring and Transfer Sequence

Under normal conditions, the ATS supplies the connected load from the utility source.

If the controller detects unacceptable utility voltage or frequency, the automatic transfer sequence begins:

• The controller sends a start signal to the standby generator
• The generator starts and begins producing power
• Generator voltage and frequency are monitored
• The load transfers after the emergency source becomes acceptable
• The ATS continues monitoring both sources
• The load retransfers after stable utility power returns
• The generator completes its cooldown cycle
• The controller sends the engine-stop command

Programmable time delays help prevent unnecessary transfer caused by brief utility disturbances.

Frequently Asked Questions

What type of power transfer does this ATS use?

This unit uses open-transition, break-before-make operation. The load is disconnected from one source before being connected to the other source.

Does the ATS automatically start the generator?

Yes. When the controller detects an unacceptable utility condition, it sends a start command to the generator. Transfer occurs after generator power reaches the programmed voltage and frequency limits.

What controller is installed in the switch?

The ATS includes the Thomson TSC 7320 microprocessor controller, which provides system monitoring, programmable timing, alarm indication, operating-status information, and event tracking.

Can this automatic transfer switch be installed outdoors?

Yes. The NEMA 3R enclosure is designed for outdoor applications and provides protection against falling rain, sleet, and normal environmental exposure when properly installed.

Is the TS 880 rated for continuous operation?

Yes. The TS 880 is designed for continuous-duty operation at its rated current when correctly selected and installed.

What short-circuit rating does this ATS have?

The available withstand and closing rating depends on the voltage, protective device, switch configuration, and approved upstream protection. Ratings may reach up to 100 kA in certain configurations, but the exact value must be confirmed from the manufacturer documentation for this part number.

Can controller settings be changed without opening the enclosure?

Many operating parameters can be accessed from the front-mounted TSC 7320 interface. This improves convenience and helps reduce unnecessary access to internal power sections.

What should be verified before ordering?

Confirm the following information before purchase:

• System voltage
• Phase
