Overview
The CTG070 is a core balance current transformer from the Carlo Gavazzi CTG series, designed for panel mounting. It features a 70 mm internal diameter opening and a fixed turns ratio of 1000:1. The device operates within a frequency range of 50 Hz to 60 Hz. It is engineered to monitor earth leakage currents when used in conjunction with compatible monitoring relays, such as the DMPUC-EL series.
Feature Summary
- Core balance design for detecting earth leakage currents
- Fixed 1000:1 transformation ratio
- Panel mount installation style
- 70 mm central aperture for conductor passage
Applications
- Earth leakage current monitoring
- Electrical protection systems
- Integration with DMPUC-EL alarm relays
Procurement Notes
Verify that the required aperture size matches the 70 mm specification of the CTG070. Confirm compatibility with the specific leakage detection relay model intended for use, ensuring the 1000:1 ratio aligns with the relay's input requirements. Check for any specific mounting hardware requirements associated with the panel installation method.
Selection Notes
Select this component when a 70 mm opening is necessary for the primary conductor. The 1000:1 ratio is suitable for sensitive leakage detection applications. Ensure the operating environment supports the standard industrial temperature range specified for the CTG series. Verify that the system frequency falls within the 50-60 Hz operational band.
Part Context
The CTG070 belongs to the CTG series of core balance transformers manufactured by Carlo Gavazzi. This series is specifically developed for electrical safety applications requiring precise leakage current measurement. The unit serves as a sensing element that converts primary leakage current into a secondary signal for processing by protective devices.
Replacement Considerations
Substitute parts must maintain the 70 mm aperture and 1000:1 ratio. Verify mechanical dimensions for panel cutout compatibility. Ensure the replacement unit supports the same 50-60 Hz frequency range and mounting configuration.
