Specification

SEODescription

The Three-phase four-pole 150A YT GZ fixed breaker is a robust 150A fixed pole switchgear designed for industrial power distribution systems. It features three-phase input and four-pole output (including neutral), directly integrating with busbar systems and modular protection relays. Rated for 150A continuous current, it operates within 380-415V AC and supports a wide temperature range (-25°C to +70°C). Compatible with communication protocols like Modbus for remote monitoring, this breaker is ideal for manufacturing plants, commercial buildings, and renewable energy installations. Its fixed design ensures high mechanical stability and simplified maintenance, though installation requires precise panel configuration. Key advantages include high short-circuit breaking capacity (up to 65kA) and compact construction, while limitations involve non-adjustable trip settings and dedicated space requirements for fixed-mount applications.
