4 MOLDED CASE CIRCUIT BREAKERS Suitable for industrial, commercial and building applications, the new version of the DWB line of WEG molded case circuit breakers was designed and manufactured according to IEC and IEC 6097-, meeting the operation and protection needs of distribution circuits up to 600 A. The Right Circuit Breaker for our Application The new version of DWB circuit breakers is available with three kinds of protection, that is, circuit breakers with Thermomagnetic protection, Magnetic protection or circuit breakers with Electronic LSI protection specific for each load type. For distribution circuits in general up to 00 A, the circuit breakers with Thermomagnetic element provide enough overload and short circuit protection for both AC and DC applications, allowing the economic and safe assembly of distribution systems. For distribution circuits from 00 A to 600 A, circuit breakers with Electronic LSI protection provide optimization of the protection circuits and higher operation accuracy by means of the following protections: Protection against overload ( L = Long time delay trip) Short-time delay trip for protection against short-circuit ( S = short-time delay), allowing selective action in case of shortcircuit currents Instantaneous short-circuit protection ("I" = Instantaneous) In applications that require the operation and protection of motor circuits, DWB circuit breakers to 00 A have magnetic protection relays especially set for this kind of load, ensuring their correct operation in case of short-circuit currents. The circuit breakers with magnetic protection for motor circuits must be combined with other operation and protection devices, such as overload relays (thermal or electronic). For the operation and protection of generators WEG DWB circuit breakers are also manufactured with protection relays especially set for that kind of load. Protecting and Disconnecting in Frames The new version of the DW line of WEG molded case circuit breakers is available from 6 A to 600 A in only five sizes, according to the maximum rated current of each frame size: DWB60 - maximum rated current of 60 A DWB0 - maximum rated current of 0 A DWB00 - maximum rated current of 00 A Note: ) With Electronic LSI protection. DWB00 and DWB00 ) - maximum rated current of 00 A and 00 A respectively DWB600 ) - maximum rated current of 600 A Molded Case Circuit Breakers

5 WEG DW molded case circuit breakers are manufactured with Quality and high-performance raw materials in order to ensure high efficiency for your application. Frame made of SMC (Sheet Molding Compound): in addition to high mechanical performance, it also presents high dielectric strength and withstands high temperatures Fixed and moving contacts made with special metal alloys to ensure safe operation and long service life Electrolytic copper terminals with surface treatment (silver-coated terminals) ensuring protection against corrosion and excessive heating of the connections Front cover made of polycarbonate (DWB circuit breakers) providing greater safety for the applications The special laser engraving system used on DWB circuit breakers ensures indelibility of the product information and characteristic along its useful life. FLEIBILIT DWB circuit breakers allow flexibility in the use of internal accessories. Interchangeability of accessories among circuit breakers from 60 A to 00 A. DOUBLE PROTECTION In order to provide greater safety for the operator, DW circuit breakers have double insulation between live parts (except for the terminals) and the front parts of the equipment. The internal accessories are completely separate from the power circuit, avoiding any risks of contact with the live parts. HIGH PERFORMANCE DWB molded case circuit breakers can be used in a wide range of applications with great performance under severe overload and short circuit conditions. When installed in motor circuits combined with WEG contactors (CWB and CWM) and WEG smart relays (SRW), they comply with coordination requirements as per IEC Molded Case Circuit Breakers

8 Protections and Settings Protections In order to meet the different requirements of the different types of load of an electrical circuit, DWB has special versions for each type of load, as shown below. Circuit breakers for distribution: thermal and magnetic protection for electric circuits in general; setting of the short circuit protection from to times the circuit breaker rated current, with tripping curve according to the criteria of IEC standard. Circuit breakers for motors: magnetic protection only. The short circuit tripping curve is set from 7. to times the circuit breaker rated current. Such setting allows starting the motor without premature trip of the protection system. It is necessary to add an overcurrent relay for protection against motor overload. Circuit breakers for generators: the protection against short circuit is set to trip up to five times the circuit breaker rated current, protecting the generator against current surges that may damage its electronics and compromise its regulation.
