THMC33 - 100A, 3-Pole, Fused Disconnect Switch

The THMC33 is a rugged, high-performance fused disconnect switch engineered for industrial and commercial environments where safe electrical isolation is non-negotiable. With a 100A rating across three poles, it delivers dependable disconnection under load while supporting strict lockout/tagout procedures for maintenance and safety.

Key advantages that set the THMC33 apart

• Three-pole, 100A fusion protection: Ideal for three-phase systems, it ensures simultaneous disconnection and fault-current interruption to protect downstream equipment.
• Reliable under-load disconnection: Designed to isolate energized circuits cleanly even while machinery is running, reducing risk during servicing.
• Lockout/Tagout ready: Facilitates compliance with safety protocols, helping protect personnel during maintenance and installation work.
• Durable industrial construction: Built to endure demanding environments, delivering consistent performance and lower downtime over the long term.

Who should consider the THMC33

Facility managers, panel builders, and automation engineers seeking a robust, code-aligned isolation device will find the THMC33 a reliable choice for safeguarding personnel and equipment during routine maintenance and fault events.

Ideal use cases

• Maintenance shutdowns on conveyors, presses, pumps, and other heavy equipment.
• Emergency or planned isolation on production lines to perform safe servicing.
• Electrical isolation in mechanical rooms and switchgear assemblies within commercial facilities.

Why this solution matters

Beyond simply disconnecting power, the THMC33 helps limit fault energy and protects downstream circuitry during faults. Its fused design provides an added layer of protection, reducing wear on downstream components and supporting safer, faster maintenance workflows.

Installation and best practices

• Integrate the THMC33 into three-phase electrical panels or switchgear configured for 100A service.
• Use proper lockout/tagout procedures during wiring and servicing to maximize safety.
• Periodically inspect fuses and terminations for signs of wear, corrosion, or looseness to maintain reliable performance.
