Battery & Charger Enclosures

Custom-Built NEMA 1, 3R and 12 Enclosures

Exponential Power designs and builds custom DC enclosures for battery systems and/or chargers. A typical cabinet integrates batteries, racking and chargers into an indoor (NEMA 1 or 12) or outdoor (NEMA 3R) rated enclosure. There are many different options and accessories available, making every system unique and built to your site-specific needs. They can be constructed with batteries, battery/charger combinations, and even DC distribution panels. Batteries can be installed on pull-out drawers or fixed shelves.

Typical Features

  • Carbon steel (0.104 – 0.125")
  • ANSI-61 gray powder coated finish
  • Continuously welded and ground smooth seams

Typical Industry Standards

  • IEC 60529

NEMA Type 1 – Enclosures are for indoor use to provide a degree of protection to personnel against access to hazardous parts and to provide a degree of protection of the equipment inside the enclosure against ingress of solid foreign objects (falling dirt). This is a basic indoor cabinet that will include venting for batteries.


NEMA Type 3R – Enclosures are for indoor or outdoor use to provide a degree of protection to personnel against access to hazardous parts; to provide a degree of protection of the equipment inside the enclosure against ingress of solid foreign objects (falling dirt); to provide a degree of protection with respect to harmful effects on the equipment due to the ingress of water (rain, sleet, snow); and that will be undamaged by the external formation of ice on the enclosure. This is a typical outdoor cabinet that will require rain hoods for the vents.


NEMA Type 12 – Enclosures are for indoor use to provide a degree of protection to personnel against access to hazardous parts; to provide a degree of protection of the equipment inside the enclosure against ingress of solid foreign objects (falling dirt and circulating dust, lint, fibers, and flyings); and to provide a degree of protection with respect to harmful effects on the equipment due to the ingress of water (dripping and light splashing). This cabinet will require NEMA 12 vents and/or cooling fans.
