T E C H N I C A L A N D A P P L I C AT I O N G U I D E5CertificationsSafeGear arc-resistant metal-clad switchgear isseismic certified to IBC region D with importancefactor of 1.5. The manufacturing locations forSafeGear are both ISO 9001 and 140001 certified.SafeGear switchgear is available with UL label oras a CSA certified lineup.Applicable standardsSafeGear is built per IEEE C37.20.2 metal-cladswitchgear construction standards and testedper IEEE C37.20.7 for arc-resistance.Arc-resistant accessibility typesPer NFPA 70E 2015 edition, Table 130.7(c)(15)(A)(a), arc-flash PPE is not required for arc-resistantswitchgear tested in accordance with IEEEC37.20.7 for racking of circuit breakers, theground and test device or the voltagetransformers as long as the following is true:clearing times are less than the rated arc-duration with the prospective fault current not toexceed the arc-resistant rating of the equipment,the equipment is properly maintained andinstalled, all equipment doors are closed andsecured, all covers are in place and secured, andthere is no evidence of impending failure. Pleasesee the NFPA 70E standard for more informationincluding definitions for properly installed,properly maintained and evidence of impendingfailure. For 2B accessibility types, the instrumentdoor is allowed to be open, but all other doorsmust be closed and secured and all other coversmust be in place and secured.Definitions are per IEEE C37.20.7 test guide.• Type 2: Front, sides and rear protection with alldoors closed• Type 2B: Front, sides, rear and LV compartment.LV compartment door can be open. All otherdoors must be closed.• Type 2C: Front, sides, rear and between adja-cent compartments and sections within a lineup• Type 2BC: Front, sides, rear, LV compartmentand between adjacent compartments and sec-tions within a lineup• SafeGear is offered in accessibility types 2, 2B,2C and 2 BC.ConstructionSafeGear is manufactured of hem bent, 14-gaugegalvanized steel for superior rust and scratch pro-tection. All non-galvanized steel parts are treatedand painted ANSI 61 gray. SaferGear‘s modularand bolted frame design with 19, 38, 57 or 95-inchcompartment sizes, provides highly flexible de-sign configurations and faster field changes toreduce downtime.Outdoor enclosuresSafeGear can be supplied in outdoor shel-tered-aisle enclosures or PDC (power distributioncenter) enclosures.Breakers used in the SafeGear platformThe SafeGear platform uses AMVAC and ADVACbreakers. More details, including detailed ratingstables, timing tables and power requirements canbe found in the AMVAC Breaker Technical Guide(1VAL050601-TG) and ADVAC Breaker TechnicalGuide (1VAL050501-TG).Instrument transformersSafeGear switchgear is available using SAB-1,SAB-1D, SAB 2 and SAB-2D CTs. Up to four SAB-1and SAB-2 CTs can be fitted per phase. Higheraccuracy SAB-1D and SAB-2D CTs are limited totwo CTs per phase. SAB-2 and SAB-2D currenttransformers are used for 3000 A breakers. Forground CT requirements, SafeGear is availableutilizing BYZ-S, BYZ-O or BYZ-L ground CTs. Thetype of CT is chosen based on the necessarywindow size required for cables and cablebending.For 5 kV applications, SafeGear switchgear uti-—General overviewSafeGear® 5/15 kV, up to 50 kA arc-resistantswitchgearSafeGear is ABB’s ANSI arc-resistant metal-clad switchgear line for short circuit currentsup to 50 kA and below at rated maximum voltages of 5 and 15 kV.
