Control transformer 400VA STN0, 4(400/230) 204984

Control transformer 400VA – reliable power supply in your installation

This single-phase transformer with a power of 400VA, designated as STN0.4(400/230), is a solid solution for reducing voltage from 400V to 230V. It will work well in both new installations and when modernizing existing ones. Its compact dimensions (121 mm wide, 88 mm deep and 124 mm high) allow for easy installation even in limited space.

Versatile application and solid construction

This transformer is designed to operate in electrical networks with a voltage of 400V, providing safe and stable 230V for devices requiring such power. Made of high-quality materials, including copper windings, it guarantees long-lasting and trouble-free operation. Insulation material class B ensures adequate thermal and electrical resistance. The relative short-circuit voltage at 5.3% indicates its ability to cope with short-term overloads.

Safety and compliance with standards

The device has a protection degree of IP00, which means there is no protection against the ingress of solids and water - therefore, care should be taken to install it in a dry and well-ventilated place. It should be remembered that work related to connecting the transformer should be performed only by a qualified electrician, in accordance with applicable standards and regulations. Although it is not a safety or isolating transformer, it provides stable voltage reduction for a wide range of applications.
