Molded Case Circuit Breakers4
The Right Circuit Breaker for Your ApplicationThe 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 800 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 500 A to 1600 A, circuit breakers with Electronic LSI protection provide optimization of the protection circuits and higher operation accuracy by means of the following protections:
In applications that require the operation and protection of motor circuits, DWB circuit breakers to 800 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.
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 60947-1 and IEC 60947-2, meeting the operation and protection needs of distribution circuits up to 1600 A.
Protecting and Disconnecting in 5 FramesThe new version of the DW line of WEG molded case circuit breakers is available from 16 A to 1600 A in only five sizes, according to the maximum rated current of each frame size:
� DWB160 - maximum rated current of 160 A � DWB250 - maximum rated current of 250 A � DWB400 - maximum rated current of 400 A
� DWB800 and DWB10001) - maximum rated current of 800 A and 1000 A respectively
� DWB16001) - maximum rated current of 1600 ANote: 1) With Electronic LSI protection.

DWB circuit breakers allow flexibility in the use of internal accessories.
Interchangeability of accessories among circuit breakers from 160 A to 1000 A.
FLEXIBILITYIn 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.
DOUBLE PROTECTIONDWB 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 2 requirements as
per IEC 60947-4-1.
HIGH PERFORMANCE
WEG DW molded case circuit breakers are manufactured with Quality and high-Performance raw materials in order to ensure high efficiency for your application.
The special laser engraving system used on DWB circuit breakers ensures indelibility of the product information and characteristic along its useful life.

Setting for Circuit Breakers (Motors)
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 5 to 10 times the circuit breaker rated current, with tripping curve according to the criteria of IEC 60947-2 standard.
� Circuit breakers for motors: magnetic protection only. The short circuit tripping curve is set from 7.5 to 15 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.

Protections
Indication LEDs
� L (Long): overload protection with reverse time-current curve and adjustable time delay� S (Short): short circuit protection with time delay, having settings of tripping current and response time, and possibility to
choose between reverse time-current curve (I²t ON) or defined time (I²t OFF)� I (Instantaneous): short circuit protection with setting of the tripping current, without setting of the response time
� The electronic protection of the circuit breaker is self-supplied. Thus, the relay will be functional for currents equivalent to 0.2 x In for three-phase circuit or 0.35 x In for one phase supplied
70% / 105%:� LED ON when 70% of In is reached� LED flashing when 105% of In is reached
� When closing the circuit breaker after a trip, one of the LEDs of L, S and I indicates which of the settings commanded the las trip, flashing ten times. After such indication, the LEDs remain OFF

BS - Undervoltage release: it trips the circuit breaker when its operating voltage is below 35% of its rated value. That is, when the undervoltage release power supply is Ue ≤0.35 x Ue, the opening of the circuit breaker is ensured. When the voltage is within the range 0.35 < Ue < 0.7, trip may occur, and above 0.7 x Ue trip will not occur.
Note: to close the circuit breaker, BS must be energized.
Guaranteed trip Possible trip
0 0.35 0.7 1.1 Ue
Guaranteed trip
0 0.85 1.1 Ue
BD - Shunt Trip: when the shunt trip is energized by a voltage pulse, the circuit breaker trips. The trip is endured when the shunt trip command voltage is Ue > 0.85. That is, when its operating range is 0.85 < Ue < 1.10 of the rated voltage, the circuit breaker will trip.
