What does this current transformer do in a power monitoring system?

It converts a high primary current flowing through a busbar into a standard 5 A secondary current that can be measured by meters, protection relays, or power monitoring equipment.

What is the current ratio and rated primary current?

The ratio is 600/5, meaning 600 A on the primary corresponds to 5 A on the secondary at rated conditions.

What secondary current does it provide?

It provides a 5 A secondary output for connection to compatible measuring or protection devices.

What accuracy classes and burdens are supported?

It is rated Class 0.5 at 8 VA and Class 1 at 12 VA, allowing you to select the class/burden combination that matches the connected load and required measurement performance.

What busbar size will fit through the window?

It is designed for busbars up to 65 x 32 mm (opening of bars 65 x 32).

What are the overall dimensions for panel layout planning?

Outside width is 90 mm and outside height is 94 mm. Depth is 40 mm (frame) and 87 mm (total).

How is it mounted onto the busbar?

It uses an insulated locking screw mounting method and is intended for direct mounting on a busbar.

What is the maximum operational voltage it is intended to be used with?

The rated operational voltage is below 720 V AC at 50/60 Hz.

What insulation ratings are provided?

Rated insulation voltage (Ui) is 3 kV and rated impulse withstand voltage (Uimp) is 3 kV. Electrical insulation class is Class B.

What is the enclosure protection rating?

It has an IP20 degree of protection, intended for installation inside suitable electrical enclosures.

What short-circuit withstand ratings are specified?

Conventional free-air thermal current (Ith) is 36 kA, and the dynamic withstand current is 2.5 x Ith.

What environmental conditions is it designed to operate in?

Operating ambient temperature is -25 to +60 °C, with permissible relative humidity from 0 to 95%.

Is the unit supplied with any sealing provision?

Yes, sealing is provided. This can help with tamper indication requirements in metering installations, depending on the overall panel design.

What standards does it conform to?

It is specified against IEC 61869-2 and VDE 0414.

What does 'tropicalised' mean in this context?

It indicates the current transformer is designed for reliable performance in harsher environmental conditions such as high humidity, within the stated operating limits (this model is described as tropicalised for busbar use).

What is the maximum safety factor and what does it indicate?

The maximum safety factor is 5. It indicates the CT’s behaviour under high current conditions relative to instrument protection, as defined by the product’s specification (for reference, this model is Schneider METSECT5DA060).
