REMOTE OPERATION
Remote switching permits operation of the circuit breaker
away from the substation at a safe distance. Direct operation
of the switchgear is one of the most frequent exercises that
exposes an operator to risk.

location, removing the operator outside the area of risk.
Benefits of retrofitting an arc proof door:
Remote switching provides a safer operating environment
• Provides safety for staff
for personnel through the proven method of adding distance
• Includes racking through closed door
between the operator and the risk at the switchgear site.
• Quick installation
Two options are available:
• Can be fitted to LMT1 and LMT2
OPTION 1 – Remote Control Panel
• Strengthens the front of the switchboard
• Dedicated control for each panel.
• Allows the breaker to be in Busbar earth position with
the door closed
• One set of trip and close operations with key to
determine panel.
• Tested to IEC62271-200 for 25ka for 1s
OPTION 2 – Remote Control Pendant
• Lead length: 10m, 15m or request.
• Plugs into panel to be operated.

RAPID ARC FLASH DETECTION
CURRENT TRANSFORMER
Rapid arc flash detection and protection offer very fast and reliable
Replace the existing cast resin Current Transformer with slip-over type:
interruption of an arc fault by tripping the upstream supply of energy
to the faulted compartment.
With a well-designed rapid arc flash system in place, an arc fault
event can be interrupted in as little as 40-50ms compared to a full
second without.
BENEFITS:
• Protects the switchgear
• Includes new Current Transformer orifice bushings and Current Transformer bushings
• Enhanced operator protection and safety
• Improved future protection flexibility
• Scalable, further arc sensors can be added in stages
• Live line indication and phasing available
• Minimises the amount of energy released
• Slip-over Current Transformer retrofit kit for LMT
• Assembled, jigged and poured in the factory
• Available in tre-foil or standard to suit both 400A/800A and 1200A panels
CONTROL CUBICLE
• Cable ends of Current Transformer bushings will match existing cable terminations
Option for replacement of the instrument cubicle, supplied
pre-fitted, wired and tested to minimise site work and time
as well as:
• New cubicle will reduce drilling and cutting on site
• Standardise switchboard arrangement
• Easy option to achieve control, metering and protection
to latest standard
• Prewired control cubicle dramatically reduces time onsite
