L8 Supplemental Protectors
UL1077 Approved up to 63 Amps
Sprecher+Schuh Series L8 Supplementary Protectors provide supplemental overcurrent protection for control circuits, solenoids, actuators, appliances, business equipment and a range of other applications where a high performance current limiting device is required. Advanced features and global approvals make them ideal for use in equipment installed throughout the world.
Broad product range
Series L8 Supplementary Protectors are available in up to 20 different current ratings from 0.5A to 63A, in one, two and three pole configurations. Over 180 base models are available with a full complement of accessories. Devices can be used in applications up to 480V AC and 48V DC with interrupting capacities up to 10kA.
Safety features provide enhanced protection
The terminals of Series L8 Supplementary Protectors provide IP20 protection 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. Sprecher+Schuh Supplementary Protectors also incorporate a trip-free mechanism — ensuring that the device operation cannot be defeated by holding the operator in the ON position.
Sprecher+Schuh Supplementary Protectors mount on a standard 35mm DIN-rail. Wire terminals accept multiple conductors, and bus bars can be used to quickly distribute power to many Supplementary Protectors simultaneously. In addition, power to the circuit breakers can be fed from the line or load side. UL508 bus bars can be used to quickly distribute power to multiple devices simultaneously.
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.
