Cutler-Hammer DH363FGK - 100A, 600V, Fused Disconnect Switch

Meet the Cutler-Hammer DH363FGK, a rugged 100A, 600V fused disconnect switch built for the exacting needs of industrial and commercial electrical systems. This unit delivers safe, reliable isolation when service and maintenance are required, with integrated fuse protection to help prevent equipment damage and downtime.

Why the DH363FGK stands out

• 100A at 600V rating – capable of handling demanding circuits in manufacturing lines, HVAC subsystems, and power distribution points.
• Integrated fuses provide immediate overcurrent protection and fast fault clearing, reducing arc exposure and safeguarding downstream equipment.
• Safe isolation under load – designed to disconnect power cleanly for maintenance without compromising safety.
• Lockout/Tagout compatibility – supports standard safety procedures, helping teams keep personnel protected during servicing.
• Durable, long-service life – engineered to endure tough environments with minimal maintenance and downtime.
• Trusted heritage – Cutler-Hammer is a respected name in industrial electrical safety components.

Practical applications and use cases

The DH363FGK is ideal for:

• Isolating power to heavy machinery on factory floors, assembly lines, and conveying systems.
• Serving as a dedicated disconnect point in electrical service panels and motor control centers.
• Providing a clear, safe shutdown during preventive maintenance, testing, or emergency isolation.

How this fused disconnect compares to alternatives

Compared with non-fused disconnects, this model adds integrated protection at the point of disconnection, enabling quicker fault response and reducing the risk of unprotected faults propagating through the system. The fused design helps ensure a fault is addressed before re-energizing, supporting safer maintenance workflows.

Robust, reliable, and purpose-built for safety and performance, the Cutler-Hammer DH363FGK empowers teams to manage power with confidence while meeting the operational demands of industrial and commercial environments.
