The Plainville Electrical Products Company

The Plainville Electrical Products Company, doing business as Plainville Electrical Products, manufactures and supplies specialized electrical components and control systems to defense and maritime agencies as a prime contractor on full-and-open federal purchase orders, with no SBA set-aside designations across its prime footprint. Headquartered in Bristol, Connecticut, the company competes predominantly on unrestricted procurements for individual electrical parts and assemblies supporting DLA and Navy logistics operations.

The company's capability portfolio centers on circuit breakers, motor control units, power distribution panels, voltage monitors, electrical contacts, semiconductor devices, gaskets, and specialized instrumentation for military and maritime applications. Recent representative work includes a $81,574.50 firm fixed-price purchase order from DLA Land and Maritime for two motor starters (awarded January 2, 2025), a $44,154.77 contract with the U.S. Coast Guard for CGC HAMILTON ventilation fan controllers (May 30, 2025), a $30,925.61 DLA purchase order for motor control components (April 30, 2024), and a $19,451.90 Coast Guard contract for a CGC STRATTON fan controller (January 23, 2023). The company manufactures products classified primarily under NAICS 335313 (Switchgear and Switchboard Apparatus Manufacturing) and NAICS codes covering relay and industrial control manufacturing and motor and generator manufacturing.

Customer concentration is extreme. DLA Land and Maritime drives 65% of recent awards (170 prime purchase orders) with $1.3 million in combined potential value, supported by a single indefinite delivery contract (DLA90088C0179) anchoring routine replenishment buys. The Department of the Navy Naval Supply Systems Command accounts for 11% of awards (28 purchase orders, $377 thousand potential value), followed by DLA Aviation (21 awards, $172 thousand) and the U.S. Coast Guard (13 awards, $173 thousand). The top five customers account for 91% of all recent awards. Award sizes are consistently sub-$100 thousand; the median award appears to cluster in the $1 thousand to $30 thousand range, reflecting DLA's tactical inventory replenishment pattern rather than large systems integration work. The company's combined obligated dollars ($21 million) significantly exceed its combined potential value ($2.1 million), indicating that invoiced performance substantially exceeds remaining ceiling values across the portfolio — a signal of mature, stable supply relationships with predictable reorder patterns.

Activity remained relatively flat over the past five years (13 awards in 2022, peaking at 16 in 2024, settling to 14 in 2025), with only two awards recorded in 2026 year-to-date as of the source date. The company operates almost exclusively as a prime contractor (97% of awards); subcontract work is limited to eight sub-awards under Electric Boat Corporation on submarine (SSBN) construction material procurements and rework efforts, awarded between October 2022 and October 2024. The vendor has been registered in federal contracting since at least 2001 and maintains an established supply relationship with DLA stretching back decades, evidenced by the consistency of part numbers, order patterns, and depot distribution cycles across the award history.
