ERTG Safety-interlocked Disconnect Cabinet

ESL’s ERTG Safety-interlocked, Fused Disconnect Cabinet provides safe power connections for Electrified Rubber Tire Gantries (or ERTGs) at container terminals, as well as other medium-voltage applications.

This unique, patent pending design allows multiple ERTG cabinets to be daisy-chained, reducing the number of costly medium voltage circuit breakers required upstream in the switch gear station.

In addition, the Safety-interlocked Cabinet prevents operators from making or breaking electrical contacts under load without the need or use of kirk locks or kirk keys.

The disconnect assembly features a 7.2kV push & pull receptacle safety-interlocked to a medium voltage switch. In addition, a mechanically interlocked internal grounding switch prevents removing the plug prior to releasing any residual voltage.

The ERTG Safety-interlocked Disconnect Cabinet offers many features to provide operators with safety and ease of use including:

• Compact footprint
• Redundant electrical safety-interlock
• Mechanical fuse tripping
• Electrically interlocked door
• Internal cabinet light
• Dedicated indicator light
• Trip indicator light
• Thermostat and strip heater
• Dead front
• Pad lockable cabinet handle
• Cabinet window
