Cutler-Hammer 2528D46G03 - 600A, 600V, 3-Pole, Fused Disconnect Switch

The Cutler-Hammer 2528D46G03 is a purpose-built 3-pole fused disconnect switch engineered for safe, reliable electrical isolation in demanding industrial and commercial environments. With a 600A rating at 600V, this unit delivers dependable disconnection under load while supporting essential lockout/tagout (LOTO) procedures to protect personnel during maintenance.

Why this fused disconnect stands out

• High-current, three-phase protection: 3-pole configuration pairs perfectly with standard 3-phase power systems, providing comprehensive isolation and protection across all phases.
• Built-in fuse protection: The fused design delivers current limiting and fault interruption, helping safeguard motors, drives, and downstream equipment.
• Safety-first maintenance: Integrated support for lockout/tagout ensures technicians can work with confidence, reducing risk during servicing and startup checks.
• Durable, field-ready durability: Engineered for long-term reliability in busy environments, where equipment faces frequent operation and service cycles.
• Trusted brand and precise specs: Cutler-Hammer quality with clearly defined electrical ratings—600A, 600V—so you can size and configure systems with certainty.

Ideal applications

• Motor feeders and large equipment disconnects in manufacturing facilities
• Process lines that require reliable, service-friendly isolation points
• Electrical service disconnects in commercial and industrial enclosures
• Maintenance shutdowns where clear, lockable isolation is essential

How it solves real problems

When downtime or unsafe maintenance routines threaten productivity, the Cutler-Hammer 2528D46G03 provides immediate, verifiable isolation. The three-pole design ensures all live conductors are separated in unison, while the fuse element adds short-circuit protection to downstream circuits. The unit’s compatibility with LOTO practices helps facilities stay compliant and reduces the risk of accidental energization during service, ultimately supporting safer, faster maintenance and more reliable uptime.
