Mersen M100J30 - 100A, 3-Pole, Fused Disconnect Switch

Meet the Mersen M100J30 — a 100A, 3-Pole Fused Disconnect Switch engineered to deliver safe, reliable electrical isolation in demanding industrial and commercial environments. Its fused design provides robust overcurrent protection and swift fault isolation, supporting lockout/tagout practices and minimizing arc exposure during maintenance.

Key features

• 100A, 3-pole configuration delivers true three-phase protection, ensuring all conductors are simultaneously isolated for clean shutdowns.
• Fused overcurrent protection interrupts fault current quickly, reducing risk to downstream equipment and wiring while simplifying fault diagnosis.
• Lockout/Tagout readiness integrates with standard safety procedures, helping maintenance teams work safely and regain control quickly after servicing.
• Durable, industrial-grade construction built to withstand harsh environments, delivering long-term reliability in daily operations.
• Ease of integration designed for straightforward installation in electrical panels and motor control setups, with practical wiring and mounting considerations.

Ideal applications

• Three-phase motor circuits, conveyors, pumps, fans, and other heavy-load equipment where dependable isolation is essential.
• Electrical rooms, control panels, and motor control centers requiring robust safety interlocks and clear disconnection points.
• Maintenance and safety-driven shutdowns where lockout/tagout procedures are a must for personnel protection.

Why this matters: the M100J30 pairs fast, reliable fault isolation with safe, controlled maintenance workflows. By delivering dependable disconnection under load scenarios and durable performance over time, it helps minimize downtime, protect critical assets, and support safer, compliant operations in demanding settings.
