Description

Built for commercial and industrial facilities maintaining older infrastructure, the L3175 provides 175A of thermal-magnetic protection. It installs into classic Westinghouse PB frame panelboards and switchboards, eliminating the need for costly retrofits or adapter kits. Delivering a 22 kAIC interrupting capacity at 480V, this 3-pole unit mount breaker features an interchangeable trip unit. It crosses over perfectly for LA3175 applications and precedes the modern LD3175 generation.
