Description
Sprecher + Schuh’s Series L9 products are thermal-magnetic (inverse time) circuit breakers offering the benefits of a modern circuit breaker design in a compact size. The L9 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 63A) 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. Protection of PLC I/O, solenoids, power supplies and control transformers along with providing the listed branch circuit protection is available in one device.
- IP20 protection for Accidental Contact
- Color-coded handle for status indicators
- Trip free mechanism
- Global approvals for worldwide acceptance
- Switching Duty (SWD) Rating from 0.5 to 20A
- 1-, 2-, and 3-pole configurations
Broad product range & flexibility:
The L9 Miniature Circuit Breakers provide a variety of product configurations by offering current ranges of 0.5A to 63A with voltage ranges of 240V AC and 480Y/277V AC. The Series L9 DIN Rail-mounted circuit breakers are similar in width and current range to circuit breakers with the added benefit of providing UL Listed and CSA 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 L9 Miniature Circuit Breakers feature finger-safe IP20 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 L9 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 L9 Miniature Circuit Breakers mount on a standard 35mm DIN-rail. Wire terminals accept multiple conductors. In addition, power to the circuit breakers can be fed from the line or load side.
