N-67A - 

Isolation transformers are power transformers for isolating equipment from direct connection to the power line. They are offered in a variety of voltage and case types. TRIAD isolation transformers are also offered in a hospital type (designated with an MD suffix), which are designed and constructed to meet the low leakage current requirements for today's medical equipment. The transformers are constructed with nonconcentrically precision-wound coils. The primary and secondary are precision wound on separate arbors, then assembled on a laminate core side by side separated by insulation. This prevents electrical connection, under normal or overload conditions, between the primary and secondary windings. These hospital type units are offered with a resettable circuit breaker, providing protection from overload and short circuit conditions. G suffix denotes ground.
