The Rolec Perific Max Fuse Protection Device is the 36mm² sensor version of Rolec’s Perific Max accessory.

ACSR0525 is listed by Rolec as the Perific Max Fuse Protection Device with 3 x 900A up to 36mm² current sensors. It appears in accessory lists across multiple Rolec charger ranges, including WallPod, Zura, BasicCharge, Quantum, Hex, SecuriCharge and UltraCharge DC products. The related ACSR0535 variant uses three 900A sensors for conductors up to 100mm². That makes the key buying difference the current sensor conductor capacity, not the product name alone. The device should be specified against the site’s charger design and measured conductor size, with the installer confirming whether the 36mm² or 100mm² sensor version is required. It is an accessory and measurement/protection support product, not a standalone EV charger. For wider equipment, see the Rolec range.

Why choose the 36mm² sensor version?

The 36mm² version is selected where the measured conductors fall within the verified up to 36mm² sensor range. That makes it the smaller-sensor choice within the supplied Perific Max pair. Selecting this version on a conductor that exceeds the sensor capacity would be a fitment error, so conductor size should be checked before ordering.

The three 900A sensors indicate a three-sensor measurement arrangement, which is relevant to larger or multi-phase charging projects where monitoring is required. The product copy should not assume the final wiring method without a site design. The installer should confirm the charger range, sensor placement and final monitoring requirements from the project documentation.

Choosing ACSR0525 or ACSR0535

ACSR0525 is the Perific Max Fuse Protection Device with 3 x 900A current sensors for conductors up to 36mm². ACSR0535 is the related Perific Max Fuse Protection Device with 3 x 900A current sensors for conductors up to 100mm². The difference is the sensor fitment capacity.

Choose ACSR0525 where the measured conductor size is within the 36mm² limit. Choose ACSR0535 where larger conductors are present and the project calls for the 100mm² sensor version. The two variants should not be chosen on price or availability alone because the sensor fitment must match the installation.

Where Perific Max appears in Rolec projects

Rolec lists Perific Max accessories on a wide spread of EV charger pages, from domestic and commercial AC chargepoints through to UltraCharge DC chargers. That broad listing makes the device relevant to many site types, but it also means compatibility should be confirmed from the specific charger and project design. A WallPod installation and an UltraCharge DC bay will not have the same electrical layout.

Perific Max should be considered alongside other supporting accessories such as CT clamps, consumer units, payment terminals and protection barriers. It is not a replacement for all protective equipment in the installation. It is one accessory within a wider electrical and charger management design.

Installer checks before ordering

The installer should identify conductor size, charger family, site supply arrangement and the required sensor location before selecting the device. The verified product description gives the current sensor rating and conductor fitment, but it does not define every installation method. Those details should come from the charger documentation and the project design.

Where network connectivity or extra inputs are required, the related ACSR0545 Perific Max LAN Accessory Input Kit may also be relevant. That is a separate accessory and should not be assumed to be included with ACSR0525. Confirm whether the project needs only the fuse protection device or the LAN input kit as well.
