Series UL-489 iniature Breakers Industrial Breakers for Branch up to 40 Amps Sprecher+Schuh includes a line of circuit breakers approved for branch circuit applications in the United States and Canada and certified as a iniature Breaker for IEC applications. Broad product range & flexibility The Sprecher + Schuh iniature Breakers provide a variety of product configurations by offering current ranges of 0.5A to 40A with voltage ranges of 240V AC and 480Y/277V AC. The Series DIN Rail-mounted circuit breakers are similar in width and current range to circuit breakers with the added benefit of providing listed branch circuit protection circuit breaker for US/Canada applications. Also available for control circuit applications are add-on auxiliary and signal contacts plus shunt trip modules to provide modern control circuit applications. A lock-off attachment is available for applications requiring that feature. Safety features provide enhanced protection The series iniature Breakers feature finger-safe IP/2 from the front of the circuit breaker to guard against accidental contact with live parts. To aid troubleshooting, a color-coded indicator provides positive visual indication of the device status (green for OFF, red for ON and isolation function). The Series also incorporate a trip free mechanism - ensuring that the device operation cannot be defeated by holding the operator in the ON position. Easy installation The Series iniature Breakers mount on a standard 35mm DINrail. Wire terminals accept multiple conductors. In addition, power to the circuit breakers can be fed from the line or load side. Global approvals for worldwide acceptance The Sprecher + Schuh Breakers are UL489 listed, CSA 22.2 No. 5.1 approved and meets IEC 60 947-2. The Series also have an HACR rating (heating and air conditioning) as well as a Switching Duty (SWD) rating from 0.5 to 20A. Switching Duty ratings are related to fluorescent light applications only, not High intensity discharge (HID) lights or any other types of loads. Advanced features and global approvals make the Series an ideal product for use in industrial equipment installed throughout the world. 24 17.5mm 35mm 52.5mm ( 11/16 ) ( 1-3/8 ) ( 2-1/8 ) One Pole Two Pole Three Pole
Product Design & Application The Series products are thermalmagnetic (inverse time) circuit breakers offering the benefits of a modern circuit breaker design in a compact size. The is used mainly in control circuit applications where branch circuit approved circuit breakers are required. Because of its range of protection (from 0.5 to 40A) many customers may use this product for protection of load devices where fuses or other supplementary protector devices previously were used in the U.S. and Canada. of PLC I/O, solenoids, power supplies and control transformers along with providing the listed branch circuit protection is available in one device. Description Breakers for Branch protection are available one (1)-, two (2-), and three (3-) pole construction and are rated 0.5 to 40A at 240VC AC and 0.5 to 32A at 480Y/277V AC for North American applications (UL 489 and CSA 22.2 No. 5.1). For IEC applications, the products are rated 415V AC 0.5 to 40A. Continuous Current Rating Standard current ratings are: 0.5A, 1A, 1.5A, 2A, 3A, 4A, 5A, 6A, 7A, 8A, A, 15A, 16A, 20A, 25A, 30A, 32A, 35A and 40A. The circuit breakers are rated in RS amperes at 40 C (4 F) ambient temperature per the UL 489 (CSA 22.2 No. 5.1) standard. This temperature is generally used as the average temperature within an industrial enclosure. If a circuit breaker is applied in a temperature that exceeds 40 C (4 F) ambient, then the circuit breaker should be derated. For IEC 60 947-2 standard, the products carry an ambient rating of 30 C. Follow standard IEC application considerations for temperature rating in different ambient temperatures. The characteristic trip curves are shown on page 40. The trip bands shown for each breaker represent current tripping limits for a circuit breaker and are within the limits established by UL. For a specific current at 40 C (4 F), a circuit breaker will open ( clear the circuit ) automatically at some total time that will be within the inimum and aximum time shown on the curves. Example: The time-current graph on page 34 shows that a one-pole, 15 A, circuit breaker trips in not less than sec, and not more than 120 sec. on a 30 A current. Because the UL standard defines this time spread, users should not specify exact tripping time. The lower current portion of the curves (upper left) depict the time to trip due to thermal action and reflect overload protection of the wire and connect load. The higher current portion of the curves (lower right) depicts the trip due to the magnetic action of the circuit breaker and reflects protection due to short circuit level currents. Compare these advanced features Line and load side terminals accept bus bar connections for reduced costs and more efficient installation of multiple devices. Box lug terminals accept #18 #6 AWG wire as standard Current limiting and interrupting capacity up to 14kA at 480Y/277V AC. Trip-free mechanism; device operation cannot be defeated by holding the operator in the ON position Amp rating and trip curve characteristic clearly marked on the device for easy identification. Available in one, two and three pole; Guarded pozidrive terminal screws with finger-safe protection to IEC 947-1 Devices install on standard 35mm DIN-rail (EN 50022) agnetic trip elements provide Type C and D trip characteristics (IEC and EN 60898), while bimetallic elements protect against slight overloads. Color coded indicator provides visual indication of the device status and isolation function 25
