Single-phase transformer PFN4201/2801 230/230V IP44 isolating enclosed portable 16152-9984

Isolation Transformer – Safety and Reliability in One Device

This enclosed, portable single-phase transformer is a solid solution for demanding applications where ensuring safety and protection against electric shock is key. Designed for both professional installers and end-users, the PFN4201/2801 model offers high reliability and durability in a housing with IP44 protection. Its advantages will be appreciated by people working in the field where mobility and resistance to weather conditions are required.

Construction and Application

The transformer is cast in resin, providing excellent electrical and mechanical insulation. The metal housing is isolated from the protective circuit and the transformer itself, increasing the level of safety. The device is equipped with a power cord with a plug, thermal fuses with reset buttons, a signal lamp, and output sockets – available in standard or on request, CEE type. Execution in Class II insulation (plug and 2-contact sockets) further increases safety.

The rated apparent power of 4200 VA allows powering various electrical devices. The transformer is used wherever galvanic isolation of circuits, protection against electric shock, or voltage stabilization is needed. It is ideal for working with power tools on construction sites, in workshops, or in the garden.

Key Features and Benefits

• Galvanic isolation: Provides complete isolation of the primary circuit from the secondary circuit, minimizing the risk of electric shock.
• High degree of protection IP44: Protects against splashing water and solid objects, enabling operation in harsh weather conditions.
• Portable design: Facilitates transport and use in different locations.
• Resin-encapsulated housing: Increases durability and resistance to mechanical damage and provides excellent electrical insulation.
• Thermal fuses: Protect the transformer from overload and short circuit – automatically switch off the device in case of failure.
• Insulation material class B: Guarantees high thermal resistance and long-term operation of the device.
• Short-circuit resistance: Increases safety and protects against damage to the electrical installation.
• Secondary voltage 230V: Allows connecting standard electrical devices without the need for additional voltage converters.

The PFN4201/2801 transformer is an investment in safety and reliability – regardless of whether you are a professional installer or an end-user. Its solid construction and advanced protection guarantee long-term and trouble-free operation.
