MASTERPACT M

FROM OBSOLESCENCE

Q-SERIES

Retrofit Tripping System for MasterPact™ Circuit Breakers

The 12Q.series trip unit has been designed and qualified in accordance with IEC/EN 60947-2 edition 4.0 (2006) and with the guidance of the LOVAG test instructions LTI IEC/EN 60947-2, ED

4.0, October 2009.This process broadly follows the same philosophy as ANSI/IEEE C37.59-2007, Requirements for Conversion of Power Switchgear, with referenced standards ANSI/IEEE C37.13-2008, C37.50-1989 (R2000) and IEEE C37.20.1-2002 requirements used as applicable.

The replacement trip element is intended to be installed on

MasterPact M/MP™ breakers that were designed by Schneider

Electric ®.The 12Q.series has been Power Lab tested on

800/1600/2000/3000 Amp frame sizes.The MasterPact™ breaker

element itself was tested by the OEM to both IEC, UL and ANSI/IEEE standards.Conversion with the 12Q.series maintains all original primary and secondary contacts, operating mechanism and interlocking systems.Since this conversion makes no changes to the legacy breaker element, the original certification reports for this product are still in effect.

High current testing was conducted at the DNV-KEMA PowerTest Laboratory in Chalfont, PA, USA; complying with EAWR (2007) clause #83.

Note: this equipment has been tested and found to comply with the limits for a class A digital device, pursuant to part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful

interference to radio communications. Operation of this equipment

in a residential area is likely to cause harmful interference in which case the user will be required to correct the interference at their own expense.

This device has been tested to with and conforms to the following standards:

EN 61326-1: 2006

EN 55011:2007

EN 6100-4-2:2009

EN 6100-4-3: 2006 +A1: 2008

Introduction:

The 12 Q-series retrofit system is designed to replace obsolete solid state tripping systems on OEM power circuit breakers.Upgrading with the 12 Q-series allows for the utilization of modern controls and safety features without significant downtime or expense.

The Q-series is designed to provide basic LSIG type protective functions.Advanced features such as Zone Interlocks must be special ordered and may not be plug-in compatible with systems supplied with original equipment.The 12 Section II manual provides detailed instructions for setting up and testing these units.

These instructions are intended to serve as guidelines to individuals with circuit breaker maintenance experience to install the 12 Q-series trip unit to replace Schneider /

Merlin Gerin / Square D STR-28D™, STR38S™ or STR-58U™ control units on the following MasterPact™ breakers:

MP08 H1

MP08 H2

MC08 N1

MP12 H1

MP12 H2

MC16 N1

MP16 H1

MP16 H2

MP20 H1

MP20 H2

MP25 H1

MP25 H2

MP30 H1

MP30 H2

MP40 H1

MP40 H2

MP50 H1

MP63 H1

MP63 H2

Kit installation requires familiarity with circuit breaker operation and maintenance, careful workmanship and compliance with all instructions.

The conversion requires removal of the existing trip unit and its replacement with the 12 Q-series.In this application, the original current sensors, flux trip actuator, and breaker wiring is utilized.The installation can be completed in approximately 15 minutes after which, the breaker must be fully performance tested.

Each kit is supplied with all of the necessary materials to upgrade the circuit breaker.In the special instance where a breaker is applied with ground fault protection on a 4-wire system, an additional neutral sensor, copper details and secondary disconnects may be required.The 12Q-series is compatible with residual “Type T” ground fault protection.If the application requires a direct-sense, “Type W” scheme, the 2Q-sereis must be specially configured at the factory.Refer to the 12Q.sereis Section II manual for more information.

Note that this retrofit kit is not intended to increase the interrupting capacity of a breaker.The converted breaker must be applied within its original short-circuit ratings.


WARNING!!

TO PREVENT ELECTRICAL SHOCK OR INJURY, DISCONNECT THE BREAKER FROM

ALL PRIMARY AND SECONDARY POWER SOURCES AND CONFIRM THAT THE BREAKER IS OPEN AND THE CHARGING SPRINGS ARE DISCHARGED BEFORE DOING ANY WORK.

REFER TO NFPA-70E FOR COMPREHENSIVE ELECTRICAL SAFETY GUIDELINES.

IMPORTANT!!

RETROFITTED BREAKERS MUST BE PERFORMANCE TESTED BEFORE BEING

RETURNED TO SERVICE.PRIMARY INJECTION TESTING IS STRONGLY

RECOMMENDED.REFER TO THE TESTING SECTION IN THE SECTION II MANUAL FOR DETAILED INSTRUCTIONS.
