Product Description: Fiberglass Build and Protection

The PSM Series is listed as an all-packaged polyester box with a fiberglass shell in black finish. Its IP66 rating indicates complete protection against dust ingress and powerful water jets, which suits locations where hose-down cleaning or weather exposure is routine.
- Fiberglass shell:Provides a non-corrosive enclosure option for plant environments with humidity or chemical exposure.
- IP66 protection:Keeps contactors, terminals, and metering components dry and dust-free, reducing unplanned maintenance.
- All-packaged type:Ships fully packaged in carton, simplifying handling for contractors and EPC buyers ordering in batches.
- CE and ROHS marking:Supports documentation needs for equipment deployed in regulated or export projects.
Operation voltage is stated as low voltage. The exact voltage class and busbar arrangement need to be confirmed against the intended distribution board.
Application Range: Low-Voltage Power Distribution
Zhejiang Tianqi Electric positions the PSM Series for power plants. In that environment, low-voltage auxiliary circuits, control gear, and metering components often need enclosures that survive heat, dust, and occasional washdown. A polyester fiberglass box with IP66 rating satisfies the baseline for many indoor and outdoor auxiliary panels.
Buyers integrating analog or digital panel meters, also part of the supplier's catalog, can consolidate sourcing for enclosure and instrumentation. The black finish and carton packaging fit standard distribution board builds, but custom cutouts and gland plate configurations are typically specified per project.
