Hammond 240CT 250VA Toroidal Isolation Transformer, 240V Plug-In

The Hammond 240CT is a 250VA plug-in toroidal isolation transformer with a 240VAC primary and 240VAC secondary, rated for 50 or 60 Hz. It provides circuit isolation for integrators, technicians and engineers who want isolated, low-noise 240V power for connected equipment without hard wiring.

The toroidal design is chosen for high isolation, low noise, light weight, cool operation and a low profile. The unit is built in a ventilated black steel case with perforated holes, and includes a rocker lighted on-off switch and a circuit breaker protected output. The 240CT is the 250VA model in the compact 8.25 in by 6.00 in by 4.00 in case, with a 2 amp circuit breaker on the output.

The input (primary) connects through a standard North American NEMA 6-15P 3-wire grounded plug; the series specification lists a 5 foot cord, while the part drawing calls out a 6 foot cord. The output (secondary) is a standard 3-wire grounded duplex receptacle (NEMA 6-15R). Overall dimensions are 8.25 in (210 mm) long, 6.00 in (152 mm) wide and 4.00 in (102 mm) high, and the shipping weight is 10.94 lbs (4.96 kg).

The 240CT carries the North American Mark of Safety, C UL and UL listed under File #E211544, and is RoHS and REACH compliant. It is for indoor use only and does not convert line frequency. Because toroidal transformers can draw a high magnetizing inrush when first energized, consider a slow-blow fuse, time delayed circuit breaker or soft start circuitry on the supply line.
