CABLE CABINET E-MOBILITY AHMA LK40424X

Charging stations are wall-mounted electrical units designed to meet the requirements and specifications of charging station standards. Temperature management is particularly critical in electric vehicle charging, so UTU charging stations always feature component-specific ventilation gaps and field-specific ventilation. The enclosure rating is IP31 due to the ventilated structure, which can be upgraded to IP34 by installing a protective cabinet (suitable protective cabinet LKS1290 no. 3436864). Charging Station Ahma LK40424X Features

• Rated current 400A (available in 250A / 315A / 400A)
• Outputs: 24 units of MCN340E (Hager circuit breaker C-curve 40A, 3-pole)
• Supply: Compact breaker HNJ400DR with busbar mounting (Hager H3+)
• Network analyzer with ModBus communication interface (Circutor CVM-C11)
• Supply connectors HYW007H (Al/Cu 2x35-300mm˛)
• Charging outputs: Al/Cu terminal connectors 2.5-35mm˛

Temperature Management

In electric vehicle charging, the output components of the station often operate near their rated current, making temperature management critically important for the station’s lifespan.

The station incorporates temperature management requirements specific to charging loads:

• Field-specific ventilation
• Air gaps in charging outputs
• Thermal emergency shutdown function

Charging output balancing factor is 1 (as required by the charging station standard).

The station features DIN rail mounting for sensors, enabling readiness for dynamic temperature management. When connected to an eParking backend system, the charging station can dynamically control charging loads based on the temperature of output components.

Lifecycle Management

The station includes a dedicated device compartment for load management devices. This device compartment is a general-purpose space suitable for installing any device. It has reserved space for the eTolppa system’s load management device (eG) to support multi-level load management. When the eTolppa load management device is installed in the station, no separate connection device is required at charging stations.

If the thermal emergency shutdown function repeatedly interrupts power supply during the station’s lifecycle, it is advisable to implement dynamic temperature management. In this mode, the backend system can continuously limit charging station loads based on the temperature of output components.

The station includes reserved space for a harmonic filter. The network analyzer can monitor the development of harmonic distortions, and a harmonic filter can be easily added later. Alerts related to harmonics can be configured on the analyzer.

The station also includes a separate compartment for spare outputs. The spare output compartment is standardly equipped with 3 units of C10 and 2 units of C16 (1-pole) circuit breakers as backup (for other electrical needs). Spare outputs are not wired to busbars.
