The Weidmüller 2556030000 is a CMA-CTM-7-50-1A-0.4VA-1 current sense transformer designed for precise measurement of load current consumption using RMS value methods. It features an asymmetrical cable feed-through design suitable for DIN rail mounting. The device operates with a primary current rating of 50 A and provides a secondary current output of up to 1 A. It has a power rating of 0.4 VA and physical dimensions of 19 mm in length, 46.5 mm in height, and supports 50 Hz frequency applications.
Verify that the specific order code CMA-CTM-7-50-1A-0.4VA-1 matches the required primary current of 50 A and secondary output of 1 A. Confirm compatibility with 50 Hz operational frequencies and ensure the 0.4 VA burden rating aligns with connected measurement devices. Check physical space constraints against the 19 mm width and 46.5 mm height specifications before procurement.
Select this component when RMS-based current measurement accuracy is required for loads up to 50 A. Ensure the application environment supports DIN rail mounting and that the connected metering device can handle a maximum secondary current of 1 A. Consider the 0.4 VA power rating to guarantee proper operation without saturation under expected load conditions.
This part belongs to the CMA-CTM series of current sense transformers from Weidmüller. It is engineered for industrial connectivity solutions, focusing on reliable current monitoring within electrical infrastructure. The model number indicates specific electrical ratings including the 50 A primary capacity and 1 A secondary output capability.
Cross-reference with other Weidmüller CMA-CTM models if different primary current ratings or secondary outputs are needed. Verify that any substitute maintains the same asymmetrical feed-through design and RMS measurement functionality to ensure system compatibility.
