Why the M200U30 stands apart

The three-pole design makes it ideal for three-phase power systems, delivering a dedicated isolation point that aligns with rigorous electrical safety practices. The fused construction integrates overcurrent protection directly into the switch path, delivering dependable disconnection under load and simplifying protection schemes in panels, switchgear, and motor control setups. This combination minimizes maintenance delays and lowers the risk of unplanned outages by providing predictable, immediate isolation when needed.

Safety, reliability, and durability your operation can trust

• Lockout/Tagout readiness: Engineered to support standard LOTO procedures, helping teams implement safe service windows and verify isolation before work begins.
• Safe isolation under load: The fused design ensures the circuit can be reliably opened and remains isolated during maintenance, reducing the potential for accidental energization.
• Rugged, long-lasting build: Designed for industrial environments, the M200U30 emphasizes durability to withstand demanding service cycles and reduce downtime.

Ideal applications

Perfect for industrial power distribution, motor control centers, service panels, and feeders where a dedicated disconnect with integrated protection is essential. It’s a practical choice for facilities prioritizing safety, compliance, and quick, reliable isolation during routine maintenance or emergency shutdowns.

Practical guidance for getting the most value

• Pair with appropriate fuses sized for your load profile to ensure optimal protection without compromising availability.
• Incorporate into your safety procedures to establish a clear, consistent isolation point at the start of every service or maintenance window.
• Schedule regular inspection of connections and fuse elements to preserve reliable performance and quick disconnection when needed.
