FENECON FEH040 3-phase sensor without current transformer

The FENECON FEH040 3-phase sensor This device captures measurement data within a compatible FENECON energy and storage system architecture. It is supplied without a current transformer and is therefore intended for systems where suitable transformers are selected separately. The unique FEH040 reference ensures correct assignment during planning, retrofitting, and replacement within the FENECON Home environment. This guarantees that the system assignment remains reliably traceable.

Delivery

1× FENECON Home 3-phase sensor FEH040
1× Communication cable with RJ45 socket
1× Connector for the communication connection to the inverter
1× Plug for connecting the current transformers
1× Connector for voltage tap
Not included: current transformer

Produktvorteile

-- Three-phase measuring component. The sensor is designed for use in a suitably configured three-phase installation.

-- Flexible converter selection. Since no current transformers are included, these are dimensioned separately to suit the specific measurement task.

Compatibility

For the Home-20/30 configuration described in the FENECON instructions at the grid connection point. External current transformers with a primary current of 200–5.000 A, a mandatory secondary current of 5 A, and an accuracy class of 0,5 or better are required. 333 mV current transformers are not suitable. System approval, dimensioning, and commissioning must be verified by a qualified electrician.

Why Mini Power

Mini Power offers the FENECON FEH040 3-phase sensor with a clearly defined scope of delivery. The note "without current transformer" is crucial for purchasing decisions and prevents the planning of an incomplete measurement solution. We transparently present the model reference, three-phase system role, and required compatibility checks. This allows electrical contractors to determine the appropriate transformers and integration into their existing FENECON system before ordering. This provides a reliable basis for electrical planning.

Frequently asked questions

Are current transformers included?

No. Suitable current transformers must be selected separately according to the system.

-- Can the sensor be operated independently of FENECON?

It is intended for explicitly compatible FENECON system configurations; the specific release must be verified.
