GHN242N - 200A, 240V, 3-Pole, Fused Disconnect Switch

The GHN242N fused disconnect switch is built for industrial and commercial environments where safe, reliable electrical isolation is non-negotiable. With a 200A rating at 240V across three poles, it delivers a clean, single-point disconnection that supports proper lockout/tagout procedures and protects personnel during maintenance, service, or emergency shutdowns. Designed for enduring performance, the GHN242N stays dependable under load and through demanding duty cycles, making it a trusted component in power distribution systems.

Key features

• 200A at 240V Three-pole configuration for complete circuit isolation.
• Fused protection Integrated fusing provides overcurrent protection and reliable disconnection when conditions exceed safe limits.
• Lockout/tagout compatibility Facilitates safe maintenance and compliance with workplace safety protocols.
• Long-term durability Engineered to perform consistently in demanding industrial environments.
• Efficient integration Designed for straightforward installation within existing electrical layouts and distribution boards.

Ideal applications and use cases

The GHN242N is the right choice for facilities and teams that need quick, dependable isolation for equipment and circuits. Use it for:

• Routine maintenance shutdowns where safe service is essential
• Emergency isolation to immediately cut power to a piece of equipment
• Service panels and distribution boards requiring a robust, fused disconnect
• Industrial machinery and commercial systems that demand reliable under-load disconnection

How it works and why it matters

When a fault or maintenance action requires isolation, the GHN242N provides a secure, fused disconnect path. The fuse element interrupts current flow, reducing the risk of arcing and damage, while the switch mechanism offers a straightforward, verifiable off position. This combination supports safe lockout/tagout procedures, ensuring that equipment cannot be re-energized until the device is intentionally serviced and cleared for operation.

Regular inspection of the switching mechanism and fuse elements will help preserve reliable performance over time.

Maintenance tips for lasting performance

• Periodically inspect the switch contacts and fuse integrity for signs of wear or overheating.
• Test the off-position operation and confirm lockout/tagout readiness during routine safety audits.
• Keep the discharge path clear and free from dust or debris that could affect connectivity.
