L9 UL-489 Miniature Circuit Breakers

Industrial Circuit Breakers for Branch Circuit Protection up to 40 Amps

Sprecher+Schuh includes a new line of circuit breakers approved for branch circuit applications in the United States and Canada and certified as a Miniature Circuit Breaker for IEC applications. The Sprecher + Schuh Breakers are UL489 listed and CSA 22.2 No. 5.1 to provide branch Circuit Breakers to IEC 60 947-2.

Broad product range & flexibility

The Sprecher + Schuh L9 Miniature Circuit 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 L9 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 L9 Miniature Circuit Breakers feature finger-safe IPX/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 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 DINrail. Wire terminals accept multiple conductors. In addition, power to the circuit breakers can be fed from the line or load side.


approvals Global approvals for worldwide acceptance. Series L8 Supplementary Protectors are UL Recognized for use in the United States in accordance with NFPA 79 (NEC, National Electrical Code). The devices comply with UL 1077 and CSA 22.2 No.235, meeting the requirements for supplementary protectors intended for use as overcurrent protection where branch circuit protection is not required, or is provided by another device such as a fuse or molded case circuit breaker. These Supplementary Protectors also comply with IEC 60898 for use in commercial and residential applications and are CE marked.
