Square D NSB 9070TF50D1 Control Transformer 50VA

The Square D 9070TF50D1 industrial control transformer (Type TF) is a 1‑phase, 50 VA device that steps 240/480 VAC primary power to a 120 VAC secondary for control circuits, rated for 50/60 Hz operation. Open‑style and panel‑mountable, it uses screw‑clamp terminals and features a top‑mounted fuse block for integrated protection, aligning with UL safety characteristics. Its compact footprint measures about 4 in high by 3 in wide by 3.09 in deep, and it employs copper windings with a 105 C insulation rating and a 55 C temperature rise to handle typical control‑system environments. The unit is UL listed and also CSA and CE certified, ensuring compliance with common electrical safety standards. For the 9070TF50D1, the primary is 240/480 VAC with a 120 VAC secondary; the TF family also includes codes for 220/440 VAC (110 VAC secondary) and 230/460 VAC (115 VAC secondary) to match different system voltages.
