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

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:

• Safety-interlocked 72kv marine grade receptacle

• Compact footprint

• Redundant electrical safety-interlock

• Mechanical fuse tripping

• Electrically interlocked door

• Internal cabinet light

• Indicator lights
