Mounting Tab/Notch: temperature_range -40°C to 150°C

Component Specifications

Definition

A precision-engineered mounting component designed to provide secure mechanical attachment and proper alignment for arc splitters and deion plates within electrical switchgear and circuit protection systems. This component ensures stable positioning while maintaining required electrical clearances and thermal management properties.

Working Principle

The mounting tab/notch functions as a mechanical interface that utilizes positive locking geometry to secure arc splitters/deion plates in their designated positions. It provides precise alignment to maintain optimal arc quenching performance while allowing for thermal expansion and contraction during operation.

Materials

High-temperature resistant polymer composite (typically glass-filled polyester or polyamide) with UL94 V-0 flammability rating, or stainless steel AISI 304/316 for high-corrosion environments.
