RCT1A and RCT5A flexible rope-type current probe

RCT1A and RCT5A Description

The RCT1A is a genuine Current Transformer (CT) replacement but has all the intrinsic benefits of a thin, light-weight, flexible, clip-around Rogowski (sense) coil. Just like a CT the RCT1A secondary output is an industry standard 0 to 1A (5VA pf 1) instantaneous current proportional to the measured primary current

Typically the RCT1A is used with power, current and power quality meters and is an ideal replacement for CTs in retrofit applications to avoid plant shutdown, applications with limited space for installation and particularly where existing monitoring equipment designed for a 0 to 1A CT input is installed.

RCT1A or RCT5A Flexible core current transformers with 1A or 5A output and avoid LV and HV shutdown

NEW COMPACT - ALL IN ONE WITH 1A or 5A OUTPUT

Model RCT1A - Any ratio from 100/1A to 50000/1A

The RCT1A and RCT5A flexible current probes have 1A or 5A secondary current output - current sensing is based on a Flexible Core Loop. Models from 100/1A to 50000/1A, Accuracy Class 1 (1%) at 5VA. UL/CSA pending

Find the most suitable option for your 1A and 5A metering requirement Options for 1A metering circuits

1. RCT1A x 3 pieces - output VA is 0.5, meaning the RCT1A needs to be situated close to your power meter. Most economical.

or

2. RCTi x 3 pieces along with TA5V-1A x 3 pieces - output VA is 5.0, high (higher than the RCT1A), meaning the RCTi can be situated close or some distance from your power meter. The advantage compared to 3. below, is that this solution is more flexible, especially if the phase cables are spread out, possibly in different areas. Single phase is also possible.

or

3. RCTi3ph x 1 piece along with TA5V-1A x 3 pieces - output VA is 5.0, meaning the RCTi3ph can be situated close or some distance from your power meter. The RCTi3ph is slightly less expensive compared to solution 2. above

Options and considerations for 5A output

1. RCT5A x 3 pieces - output VA is 0.5, meaning the RCT5A needs to be situated close to your power meter

or

2. RCTi x 3 pieces along with TA5V-5A x 3 pieces - output VA is 5.0, high (higher than the RCT5A), meaning the RCTi can be situated close or some distance from your power meter. The advantage compared to 3. below, is that this solution is more flexible, especially if the phase cables are spread out, possibly in different areas. Single phase is also possible.

or

3. RCTi3ph x 1 piece along with TA5V-5A x 3 pieces - output VA is 5.0, meaning the RCTi3ph + TA5V-5A can be situated close or some distance from your power meter. The RCTi3ph is slightly less expensive compared to solution 2. above

Examples of RCT1A RCT5A current sensor order codes

RCT1A / range / power supply / coil length mm

100A range, 1A output with 12-24Vdc power and 300mm coil length = RCT1A / 100A / D24 / 300

RCT5A / range / power supply / coil length mm

500A range, 5A output with 12-24Vdc power and 500mm coil length = RCT5A / 500A / D24 / 500

Optional 3.5mm diameter 100, 200 or 300mm sense coils

* to meet CE / UL safety requirements, an external power adapter is supplied for 125Vdc, 110Vac and 230Vac options

All products have CE, IEC, EN, ASME or BS approvals.
