Overview
About the Omicron CT Analyser Switch Box (CTSB2)
Description
The CT Analyser Switch Box Expansion is an optional accessory designed to streamline multi-ratio and multi-core current transformer (CT) testing using the OMICRON CT Analyzer. It enables automatic or semi-automatic switching between different CT taps or cores without needing to manually disconnect and reconnect leads. This significantly reduces test time, improves safety, and ensures repeatable, accurate results. Ideal for testing multi-tap CTs in protection and metering systems during commissioning or maintenance, the switch box is especially useful for applications involving multiple burden or ratio combinations.
Features
• Expands testing functionality for CTs with multiple ratio taps or cores
• Supports up to 6 secondary taps per CT without manual rewiring
• Seamless integration with OMICRON CT Analyzer and CT Analyzer Suite software
• Reduces test time and human error during tap or core selection
• Operated via rotary selector or remote control (model dependent)
• Improves safety by reducing disconnection risk under test voltage
• Clearly labelled terminals for easy setup in the field
• Compact, lightweight, and ruggedised for substation use
• Supplied with terminal blocks, cables, and carry case

Calibration
All Megavar test equipment is maintained under a documented calibration programme. Instruments are calibrated either by external calibration laboratories or in-house against reference standards that are themselves laboratory-calibrated, with measurement traceable to Australian national measurement standards held by the National Measurement Institute. A current calibration certificate is available on request. If your project requires a specific calibration interval, test standard, or documentation for a client submission, tell us at enquiry on 1300 730 499 and we will confirm what applies before you commit.

How the hire works
Hire terms in brief
After you enquire
We confirm availability, rates and freight in a written quote, valid for the period it states (usually 14 days). An enquiry or quote does not reserve equipment: the hire is booked when your purchase order, signed quote or email acceptance reaches us.
Hire period
Our carrier: up to 72 hours of transit each way is not charged as hire. Hire starts at delivery or 72 hours after dispatch, whichever is earlier, and ends at handover to our carrier or 72 hours before the equipment arrives back, whichever is later. Delay caused by us or our carrier is not charged. For example, dispatched Monday 10am and delivered Wednesday 2pm: hire starts Wednesday 2pm. Routes that normally take longer than 72 hours are marked on the quote. Your own freight: hire runs from handover to your carrier at our office until the equipment arrives back at our office. Collect in person: from collection to return.
Extensions and early return
Contact us before the return deadline to extend; your quoted rates stay fixed and extended hire is invoiced every 7 days. Return early and you pay only for the days used, at the rate band for the days actually hired.
Delivery and returns
Freight for each leg, the handling fee and any express dispatch are on the quote, before you accept. Returns go to the dispatching office named on the quote, by carrier or in person, never by post.
Counter times
Returned to our counter before 9am on a business day counts as the previous day. Collected after 4pm on a business day, hire starts the next day. Weekends and public holidays count as hire days.
Calibration and checks
Supplied in working order with listed accessories, leads and manuals. Each measuring instrument is calibrated, and its current NATA-traceable calibration certificate is available on request. If calibration falls due during your hire, we tell you before dispatch.
Cancelling or moving a booking
Cancel 5 or more business days before dispatch or collection and nothing is charged. With 2 to 4 business days’ notice, the charge is the greater of one day’s hire and 5% of the booked hire; with less notice, the greater of one day’s hire and 10%. You can ask once to move the start by up to 30 days, with at least 2 business days’ notice.
Loss, damage and insurance
The equipment is your responsibility, other than fair wear and tear, from the start of hire until it is back with us, including in transit, up to the replacement value cap shown on the quote for each item. No damage waiver is offered. We recommend you insure the equipment for its replacement value.
Payment and bond
Account customers pay each invoice within 14 days. Without a credit account, or paying by card, you pay the booked hire, freight, handling fee and any bond before dispatch. A bond applies only where the quote states one, and is refunded after return and inspection, less anything owed.

FAQ
Frequently Asked Questions
Omicron CT Analyser Switch Box (CTSB2)
What is the CT Analyser Switch Box used for?
It is used to quickly and safely switch between different CT taps or cores during testing with the OMICRON CT Analyzer, eliminating the need to manually reconnect wires between tests.
How many taps or cores can it support?
Most models support up to 6 secondary windings or taps. This is ideal for CTs with multiple ratios or cores used in protection and metering.
Is it compatible with all CT Analyzers?
It is designed to work specifically with OMICRON CT Analyzer units and integrates fully with PTM (Primary Test Manager) software.
Do I need the switch box for every CT test?
No. It is most beneficial when testing multi-tap or multi-core CTs where repeated reconnection would otherwise be required. For single-ratio CTs, it’s not essential.
Does it require its own power source?
No. It is a passive switching device controlled by the CT Analyzer or manually, depending on the model.
What’s included with the rental?
The rental includes the switch box unit, terminal blocks, interconnect cables, and a carry case. It is typically hired alongside a CT Analyzer.
Can I hire it with a CT Analyzer package?
Yes. We offer bundled CT Analyzer + Switch Box packages to simplify multi-tap CT testing.
What support comes with the hire?
Each instrument is supplied with the manufacturer’s manuals. If a set plays up, call us and we will arrange a fix or a replacement.
What is the minimum hire period?
The minimum hire is one day. The daily rate steps down for hires of 8 days or more, and longer project hires can be quoted on 1300 730 499.
Do you deliver across Australia?
Yes. We provide nationwide delivery and pickup, or you can arrange your own freight.
