The HX94A is a 600V instrument potential transformer from the EX-HX-VT Series with a 600:120 ratio and the series' higher 0-20 VA burden rating. It lets a 150 Volt full scale A.C. voltmeter measure the voltage of a 600 VAC system and is intended for low-voltage switchgear and motor control panels where a heavier metering load is expected.
Electrically, the HX94A is rated for 50/60 Hz operation with 600:120 primary-to-secondary ratio, 1.2% accuracy, a 0-20 VA burden range and a thermal rating of 100. 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 3.75 in (95 mm), B 4.00 in (102 mm) and C 3.13 in (80 mm), with mounting centers D and E both 3.13 in (80 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 6.6 lb; the part page lists 6.48 lbs (2.94 kg). For the same 600:120 ratio in a smaller 0-8 VA package, see the VT59A.
The HX94A is CSA certified (209651) and listed as RoHS and REACH compliant.
Ideal For
- Voltage metering in low-voltage switchgear
- Motor control centre voltmeter circuits
- Driving 150 Volt full scale A.C. voltmeters on 600 VAC systems
- Panel instrumentation on 50/60 Hz systems
