ACREL 50II Current Transformer for Electrical Monitoring
ACREL 50II Current Transformer for Electrical Monitoring is a fixed-type AC measuring transformer for monitoring electrical current through busbars or cables. The 50II configuration provides a 52 x 32 mm through opening and is designed for a 50 x 10 mm busbar arrangement. Available ratios include 150/5 A, 200/5 A through 250/5 A, 300/5 A through 450/5 A, 500/5 A through 800/5 A, 1000/5 A through 1250/5 A and 1500/5 A, with the applicable accuracy and burden depending on the selected ratio.
The ACREL 50II Current Transformer for Electrical Monitoring is part of Acrel's measuring current transformer range for low-voltage electrical systems. The transformer operates by passing the monitored conductor through its core and producing a proportional secondary current for connection to suitable measuring or monitoring equipment.
The 50II model is suited to installations where the conductor or busbar arrangement fits its specified through dimensions. Acrel lists several primary current ratios for this size, allowing the transformer to be selected according to the electrical measurement requirement.
How it works
- The primary conductor passes through the current transformer's opening.
- Current flowing through the primary conductor creates a magnetic field in the transformer core.
- The transformer produces a proportional secondary current, such as 5 A, for compatible measuring equipment.
- The secondary signal can be used by electrical meters and monitoring systems designed for the selected transformer ratio.
Acrel describes the AKH-0.66 range as converting primary current into 5 A, 1 A or mA signals for measurement and monitoring applications.
Why choose this product
- Multiple current ratios: The 50II configuration is available across a range of primary current ratings.
- Defined physical dimensions: The 50II version provides a 52 x 32 mm through opening and is specified for a 50 x 10 mm busbar arrangement.
- Measurement accuracy options: The series is available in Class 0.2, Class 0.5 and Class 1.0 configurations, depending on the selected ratio.
- Flexible installation: The AKH-0.66-II series supports installation using sheet metal, clutch cover or 35 mm DIN rail arrangements.
Benefits
- Provides a proportional current signal for compatible electrical measuring equipment.
- Allows higher AC currents to be monitored without connecting the primary current directly to a measuring instrument.
- Suitable for integrating current measurement into low-voltage electrical monitoring systems.
- The 50II format provides a defined mounting and conductor clearance arrangement for compatible installations.
