The Rolec Zura Smart 22kW 3 Phase Socketed EV Charger is a black Mode 3 chargepoint for sites with a 400V AC three-phase supply. ROLEC3046B provides one Type 2 IEC 62196 socket with output up to 22kW at 32A, making it a higher-output Zura option for workplaces, residential developments and car parks with suitable electrical capacity. The socketed design leaves cable length to the user, which is useful where different vehicles and drivers use the same bay. It supports plug and charge, mobile app and RFID operation, plus OCPP 1.6J for compatible chargepoint management systems. Built-in Class 1 MID compliant metering supports accurate reporting. The Zura enclosure is IP65 rated, impact protection is IK10 and the standard unit colour is black. Three-phase dynamic load balancing requires the optional ACSR0325 CT kit rather than the single-phase included CT kit. See more commercial EV chargers.

Where a 22kW Zura makes sense

A 22kW AC charger only makes sense where the site has a suitable three-phase supply and the electrical design allows the demand. The 22kW Zura is not a faster replacement for a single-phase domestic chargepoint on a standard 230V supply. It is a three-phase model for sites where 400V AC is available and where the user base or dwell time can benefit from higher AC charging output. Workplaces, shared residential car parks and managed destinations are the natural use cases.

The vehicle also has to be considered. Some vehicles accept less than 22kW on AC, so the charger rating is only one part of delivered charging performance. For site owners, the benefit is capacity at the bay and the ability to support vehicles that can take higher AC rates. For installers, the key checks are supply capacity, protective device selection, network connection and whether dynamic load balancing is required. That makes the 22kW Zura a design-led specification rather than a like-for-like upgrade from a 7.4kW unit.

Socketed flexibility for shared three-phase bays

The socketed 22kW variant uses a Type 2 IEC 62196 socket rather than a fixed lead. That format suits shared parking because the driver uses the cable that matches the vehicle and bay arrangement. It also reduces exposed cable storage at the chargepoint when the bay is empty. For a site with different users, different vehicles and different cable preferences, socketed hardware can be simpler to maintain visually than a long tethered lead.

The trade-off is that a cable must be available before charging starts. Staff or residents may already carry Type 2 cables, while visitors may need clear site instructions. Where a site controls the bay closely and wants a lead always ready, the 22kW 5m tethered Zura variant is the closer match. Where the bay is shared and users bring cables, ROLEC3046B gives the higher-output Zura hardware without imposing one fixed cable length on every driver.

OCPP, RFID and metered energy reporting

OCPP 1.6J support gives the three-phase Zura a route into compatible chargepoint management systems. That matters on commercial, residential and public-facing sites where charge sessions may need to be authorised, recorded or billed through a back office. RFID operation supports controlled access at the point of use, while mobile app operation gives another user route for managed charging. Plug and charge remains available where the site wants simpler operation.

Integrated Class 1 MID compliant metering supports accurate energy consumption reporting. That is particularly relevant for tenant billing, staff reimbursement, visitor charging and internal cost allocation. Combined with OCPP support, the meter helps the chargepoint fit into a managed estate rather than sitting as a standalone electrical load. The configurable RGB LED status halo provides local status feedback for the driver and site staff, which helps identify whether the charger is available, active or awaiting user action.

Three-phase protection and load management

The Zura protection package includes TruePEN PME fault detection, over current protection, 6mA DC fault protection, lightning surge protection and over temperature protection. A dedicated 30mA Type A RCBO or equivalent protection is required at source, so final protection design needs to be confirmed by the installer. Cable terminals for three-phase are specified as 5 x 50mm for three phases, neutral and earth, which helps when planning cable size and termination.

Load management must be checked carefully on three-phase sites. The Zura data sheet states that dynamic load balancing includes CT clamp and cable for single-phase models, while three-phase models require the optional ACSR0325 CT kit. That difference matters at quoting stage because a three-phase installation may need extra hardware to deliver the intended load management function. Static load management is software configurable, giving another way to restrict demand where supply capacity is limited or multiple chargers are planned.

Outdoor housing and mounting options

The Zura enclosure measures 260mm wide, 410mm high and 157mm deep. The unit and fascia are made from high impact resistant polycarbonate, with a steel mounting back plate and a stainless steel rear bracket plate. The enclosure is rated IP65, the socket is rated IP54 and the design is IK10 impact resistant. Those ratings support exposed outdoor locations, subject to normal installation practice and local site assessment.

The standard unit colour for this SKU is black. Fascia colour options in the range include black, grey, white and branded or customised fascias. That can matter on commercial and residential sites where the chargepoint needs to align with building finish or site identity. The independent back plate supports wall or post mounting, and the Zura mounting post fits up to two units when an off-wall position is needed. Post use should be planned with bay marking, cable reach and accessibility requirements in mind.

Choosing between 22kW Zura variants

ROLEC3046B is the 22kW three-phase socketed Zura with one Type 2 socket. ROLEC3156B is the related 22kW three-phase model with one 5m Type 2 tethered lead. The electrical output is the same up to 22kW, but the user experience differs. Socketed hardware is better for shared bays where users can bring different cable lengths. A tethered 5m unit is better where the vehicle parks close to the charger and the site wants a lead ready at the bay.

The 7.4kW Zura variants should be specified for single-phase installations. ROLEC3020B and ROLEC3030B cover one or two socketed 7.4kW outlets, while ROLEC3140B, ROLEC3150B, ROLEC3145B and ROLEC3155B cover 5m and 10m tethered choices. Moving to the 22kW model changes the supply requirement to three-phase. It should be driven by site capacity and vehicle use, not just by the desire for a higher number in the product name.
