Opus - Operator Protection Upgradeable Safety

Fuse rails and fuse switch disconnectors

Opus Intra, Opus Plus and Opus Excel have been developed by Merlin Gerin to offer you protection utilising blade type fuselinks to IEC 60269-2-1 and a choice of increased operator safety to suit your application.

Opus Intra – standard safety
Fuse rail or fuse base

Opus Intra fuseway base is moulded from durable, flame retardant material
A robust base for fuse contacts and solid outgoing tin plated copper connections
Additional shrouding of the Opus Intra fuseway base provides IPXXB operator protection from live conductors when the fuselinks are not in service, or with insulated blade type fuselink tags
Available in ratings of 400A and 630A, Opus Intra accepts manually inserted size 2 and 3 fuselinks respectively
Manual insertion of fuse links is achieved with a hand held fuse puller
Opus Intra fuseway provides a cost effective, simple installation with minimal maintenance

Opus Plus – increased safety
Manual fuse switch disconnector

Increased levels of operator protection are achieved with Opus Plus
Maximum flexibility in providing 12 possible distribution solutions
Fully shrouded fuselinks in fuse carriers
Manual switching is achieved via levers to move the fuse carriers to either the ‘on’ or ‘off’ positions
A parallel switching action contacts with arc control, ensures a swift opening and closing of the circuit
Operator protection from live conductors in the ‘on’, ‘off’ or transitional positions
Opus Plus is available in ratings of 400A and 630A as either a single pole or triple pole switching operation
Solid outgoing tin plated copper connections accommodate a cable lug or mechanical connector termination up to 300mm2
Facility for top or bottom cable entry, or alternatively to the left hand or right hand side

Opus Excel – optimum safety
Independent manual fuse switch disconnector

Operator protection from live conductors to IPXXB during all operating conditions
Mechanical spring assisted switching mechanism enables safety of the highest levels to be achieved. Switching mechanism engages with each fuse carrier in turn to produce an AC22B fault make, load break fuse switch
Fully interlocked to ensure correct operation and does not rely on the skill of the operator, or the speed at which the lever is moved The mechanism is the only means of driving the fuse carrier to the ‘on’ or ‘off’ positions
Facility to remotely monitor the ‘on’ and ‘off’ status of the outgoing circuits
Opus Excel is available in ratings of 400A and 630A with solid outgoing tin plated copper connections
Can accommodate a cable lug or mechanical connector termination up to 300mm2
Facility for top or bottom cable entry, or alternatively options to the left hand or right hand side
