LYB255-LYB258 1250A Contact Arm Moving Contact – High-Voltage Insulating Sleeve with Silicone Rubber for VCB Switchgear

The LYB255-LYB258 is a high-performance 1250A contact arm designed for critical insulation and support in high-voltage vacuum circuit breakers and switchgear systems. This specialized assembly consists of a high-purity conductive conductor protected by a durable silicone rubber contact arm sleeve. The insulating sleeve is precision-fitted over the live conductor to provide superior dielectric protection and structural support. Featuring a multi-shed profile to maximize creepage distance and prevent surface tracking, these contact arms ensure safe and reliable power transmission in demanding electrical distribution environments.
