CABLE CABINET E-MOBILITY AHMA LK25418X

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 LKS1090 no. 3426358). Charging Station Ahma LK25418X Features

• Nominal current 250A (available in 160A / 200A / 250A)
• Outputs: 18x MCN340E (Hager circuit breaker C-curve 40A, 3-pole)
• Input: Compact breaker HNJ250DR with busbar mounting (Hager H3+)
• Network analyzer with ModBus communication (Circutor CVM-C11)
• Input 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 nominal current, making temperature management critically important for the station’s lifespan.

The station incorporates temperature management requirements specific to charging load:

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

Charging output balancing factor 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 load based on the temperature of output components.

Lifecycle Management

The station includes reserved space for load management devices. The load management space is a general device compartment suitable for installing any device. Reserved space is provided for the eTolppa system load management device (eG) to enable 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. Alarms related to harmonics can be configured on the analyzer.

The station also features a separate compartment for spare outputs. The spare output compartment includes standard spare circuit breakers: 3x C10 and 2x C16 (1-pole) (for other electrical needs). Spare outputs are not wired to busbars.
