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 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
- Cabinet heater
- Dead front
- Padlockable handle
