The VT59A is a compact 600V instrument potential transformer in the EX-HX-VT Series, stepping a 600 VAC line down at a 600:120 ratio for use with a 150 Volt full scale A.C. voltmeter. It is built for voltage metering in low-voltage switchgear and motor control equipment on 600 VAC systems.
Electrically, the VT59A is rated for 50/60 Hz operation with 600:120 primary-to-secondary ratio, 1.2% accuracy, a 0-8 VA burden range and a thermal rating of 50. The primary is insulated for a 4.0 KV rms test, and the insulation system is Class 105 with a 55 degree C rise.
Construction is open "Type H". Overall dimensions are A 3.00 in (76 mm), B 3.25 in (83 mm) and C 2.56 in (65 mm), with mounting centers D and E both 2.50 in (64 mm) and mounting slots of 0.22 in (6 mm) (G) by 0.44 in (11 mm) (H). The spec sheet lists a ship weight of 3 lb; the part page lists 2.35 lbs (1.07 kg). For the same 600:120 ratio in a larger 0-20 VA package, see the HX94A.
The VT59A is CSA certified (209651) and listed as RoHS and REACH compliant.
Ideal For
- Voltage metering in low-voltage switchgear
