Product Description

The SQUARE D S37450 is a lug shield accessory designed for use with long lug configurations on PowerPact J-Frame circuit breakers. It provides a protective cover over exposed lug terminations, reducing the risk of accidental contact with energized conductors during normal panel operation. This component is a factory-style replacement or supplemental accessory installed by licensed electricians during breaker installation or panel maintenance. It measures 7.4 inches in length, 4.6 inches in width, and 4.9 inches in height, making it sized specifically for J-Frame hardware.
