Thomson TS880SE Manual Transfer Sw (3Ph, 2500A)

This Thomson TS 880 SE Manual Transfer Switch is ideal for mission critical commercial and industrial service entrance applications up to 2500A. Optional Bypass Isolation available.

TRANSFER SWITCH FEATURES

• Numerous three phase voltages available up to 600V – 3-wire or 4-wire systems. Three or four poles.
• Manually initiated and electrically operated with Source Selector Switch, Position Indicating Lights, and Source Available Lights.
• All load transfer sequences are “Open Transition” (i.e. “break-before-make”).
• Solid Neutral standard on 4 wire systems. (Please inquire about other options.)
• Fully enclosed silver alloy contacts provide high withstand rating & 100% continuous current rating.
• 3 cycle short circuit current withstand tested.
• Completely separate utility and generator side power switching units.
• Superior serviceability with all mechanical and control devices visible and readily accessible.
• ISO 9001 registered for quality assurance.
• NEMA 1 enclosure standard with options of NEMA 3R, NEMA 3RX, and NEMA 12.
• Seismic Certified for installation and operation per the following requirements: IBC 2012 – Section 13, Occupancy Category IV; ASCE7-05 Region 3 (minimum SS=200%); and OSHPD Certified.
• Specifically designed and certified to UL 1008 Standards.

SERVICE ENTRANCE FEATURES

• Incorporates an isolating mechanism and over current protection on the utility supply thereby removing the need to have a separate, upstream circuit breaker/ disconnect switch.
• Utility switching device is an insulated case switch with Electronic Trip (Electronic and GF Trip also available – required for most 240V applications).
• Can be applied to any TS 880 model of Thomson Power Systems Transfer Switch.
• Simple service disconnect operation ensures a high level of safety for system maintenance personnel.
• Pad-lockable Service Disconnect control switch.
• Incorporated into a standard sized automatic transfer switch enclosure.
• Specifically designed and certified to the UL 1008 Standard as well as complying with NEC and NFPA requirements.
• Optional generator-side over-current protection with Electronic and GF Trip available.

BYPASS ISOLATION OPTION

• Employs an interlocked power switching mechanism that provides an easy and safe procedure for system maintenance personnel to manually isolate and bypass the transfer switch.
• Manually operated switch allows either generator or utility source to be bypassed to maintain power to the load while the transfer switch is tested for maintenance procedures as required.
• Allows a fast, simple and reliable method of isolating and bypassing the transfer switch through a “break-before-make” bypass design.
• Mechanical interlocking mechanism ensures that the utility and generator sources cannot be paralleled under any circumstance and the transfer switch may be bypassed to either source.
• Supplied as a single complete assembly with all power conductors provided between the bypass mechanism and the transfer switch.
• Provisions for all external power cabling for the utility, generator and load conductors are provided for in the bypass/isolation compartment of the switch.
• Bypass/isolation switch and transfer switch are mounted in separate barriered compartments.
• Bypass isolation mechanism consists of 2 mechanically interlocked power switch devices and draw-out transfer power switching devices with key interlock mechanism.
• Utilizing independent switching units provides a high degree of reliability and redundancy not available in other switches.
• Specifically designed and certified to UL 1008 Safety Standards.
