These circuit breakers can be identified by a label stating that they are subject to this exchange policy. llowance replacement circuit breaker within the same frame size, but of a different trip rating than that exchanged, is furnished at the lowest recognized competitive list price for a trip unit of the same frame size and trip rating minus the regular discount. This exchange arrangement requires that the replaced circuit breaker be returned to Square. TLO NUMRS Square circuit breakers are ordered by a catalog number that includes the breaker family, description, poles, voltage rating, amperage rating and suffix. igure 5 shows a catalog number broken down by components. or example, L3V2, a typical catalog number, can be broken down as follows: frame circuit breaker L ircuit breaker with lugs on both ends 3 of poles Voltage rating 0 ontinuous current amperage rating (handle rating) V and 2 V indicates the Visi-lade feature and the 2 indicates a factory installed contact alarm. These two components are the suffix.

In contrast, the curves show that with the same level of,000 rms symmetrical short circuit amperes available, the ampere current limiting circuit breaker would limit the energy flow 0.2xl0 ampere 2 second at 4 volts or 0.27xl0 ampere 2 seconds at 2 volts. SPIITIONS ases for molded case circuit breakers are constructed of a glass-reinforced insulating material that provides high dielectric strength. urrent carrying components are isolated from the handle and accessory mounting area. The handle position indicates whether the circuit breaker is O, ON or tripped. Square molded case circuit breakers: have common tripping of all poles are equipped with a Push-To-Trip button to manually trip the circuit breaker can be mounted and operated in any position are fully tested, UL Listed, S certified and I rated for reverse connection without restrictive "LIN" or "LO" markings 10,000,000,000 vailable Short ircuit urrent MXIMUM LT-THROUH l t NRY ONSTRUTION Square thermal-magnetic circuit breakers are manufactured and tested according to the following standards and files: UL Standard 489 NM Standard -1 anadian Standards ssociation (S) ile LR7551 International lectrotechnical ommission (I) 7-1 ederal Specification W--375/N as lass lla, lib; 12a, 12b; and 13a, 13b Magnetic only circuit breakers are manufactured in accordance with the following standards: UL ile 27 S ile LR323 Molded case switches comply with: UL 1087 ULile33117 UL ile LR 323 Note: ircuit breakers are to be applied by guidelines detailed in the N and other local electrical codes. TRIPPIN SYSTM Square thermal-magnetic molded case circuit breakers have a permanent trip unit that contains a factory preset thermal trip element and a magnetic trip element in each pole. The thermal trip element is rms sensing. In circuit breakers with frame sizes greater than, the magnetic trip element is field adjustable. single adjustment simultaneously adjusts the instantaneous trip point in each pole. TRMINTIONS ll factory installed mechanical type lugs are UL Listed to accept solid or stranded conductors and can be used with wire rated at, 75 and (sized according to the N 75 temperature rating). Most molded case circuit breakers are UL Listed to accept field installable mechanical type and compression type lugs. UL RQUIRMNTS UL label on a Square molded case circuit breaker indicates that the circuit breaker meets the requirements of UL Standard 489 for circuit breakers. UL label also means the production procedure is monitored by UL inspectors for continuing conformance to UL performance requirements. These requirements are based on sound engineering principles, research, records of test and field experience, and information gathered from users and inspection authorities. These requirements are subject to revision as necessary. UL HR TYP Type, H, K, and KH industrial molded case circuit breakers are UL Listed as HR type. -SQUR QMWMY-
