Thomson TS880 Manual Transfer Switch (3Ph, 1600A)

This Thomson TS 880 Manual Transfer Switch is ideal for mission critical commercial and industrial three phase applications up to 1600A. 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 CSA 178 & UL 1008 Standards.

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 and CSA 178 Safety Standards.
