Tense AT-50 50/5A 30mm Measurement Current Transformer
The Tense AT-50 is a professional grade measurement current transformer (CT) designed to safely step down high capacity primary line currents within electrical distribution panels and low voltage industrial systems. Featuring a precise transformation ratio of 50/5A, this device effectively converts primary load currents up to 50 A into a scaled 0–5 A secondary output, enabling accurate data acquisition by ammeters, power analyzers, and automated control devices. Outfitted with an expansive 30 mm rectangular/busbar window opening, it offers high versatility, accommodating thick insulated cables or copper busbar layouts.
Key Features
-
High Accuracy Current Scaling: Engineered to support precise power monitoring and instrumentation with reliable signal transformation.
-
30 mm Window Opening: Designed with a spacious rectangular profile tailored for seamless installation over solid busbars or thick insulated phase lines.
-
Hinged Safety Terminal Guards: Features clear protective flip covers that shield the secondary contacts (S1 and S2) to guard maintenance technicians against accidental contact.
-
Flame Retardant Casing: Enclosed in a compact, durable self extinguishing polymer body that maintains absolute mechanical and thermal stability under continuous peak current operations.
-
Integrated Panel & Base Mounting: Includes robust mounting flanges and structural clips to allow secure fastening onto internal panel baseplates or distribution walls.
