What Mechanical Products does
Mechanical Products Company (MP), founded in 1943 and headquartered in Lombard, Illinois, is a privately-held, management-owned US manufacturer of thermal circuit breakers and circuit protection devices. The company produces 13+ product series spanning 0.5 to 300 amps — covering push-to-reset, switchable, auto-reset, high-amp, waterproof, and ignition-protected configurations — based on bi-metal snap-action electromechanical technology that uses differential expansion of dissimilar metals to force mechanical contact opening under overcurrent conditions. Notable proprietary features include the LED tripID visual trip indicator (registered trademark), high-temperature recyclable thermoplastic housings, permanent resistance welding of contacts, IP67/IP69K ingress protection on Series 19, and a class-leading 56VDC maximum voltage rating on Series 87. The company holds ISO 9001:2015 certification and complies with UL1077, UL489, UL1500, SAE J553/J1171/J1428, ABYC E-11, MIL-STD-202, UL1107, RoHS, REACH, and Prop65 across the product line.
Mechanical Products serves seven primary end-markets: industrial manufacturing, truck/bus/RV, marine, construction/agricultural, medical, military vehicles, and specialty vehicles. It is the sole remaining US-based manufacturer of broad-range thermal DC and marine-rated circuit breakers, producing approximately 80% of goods domestically and operating manufacturing facilities in Lombard, IL and Jackson, MI alongside a China production facility. Revenue is generated primarily through hardware sales (Series 02 through Series 87) via a curated global network of 20+ authorized distributors (Wesgarde, Waytek, Chief Enterprises, Hughes Peters, Simcona, Osculati, Swe-Check, etc.), complemented by a direct enterprise field sales motion, an IMDS-led European sales agency, a Netherlands 3PL warehouse for EU fulfillment, a Digi-Key Marketplace listing for prototype design-in activity, and a custom engineered product development service. Pricing is quote-based B2B with multi-year contract cadence and no public price disclosure.

Mechanical Products competitors and assessment
Company assessmentBroad incumbents
- Hubbell: Hubbell manufactures electrical wiring devices, circuit protection and connectors for industrial, utility and construction markets. It overlaps MP in specialty vehicle, marine and industrial protection devices within a much broader wiring and connector portfolio.
- ABB: ABB offers a broad portfolio of switchgear, circuit breakers and electrical distribution equipment from low-voltage to utility scale. It competes indirectly with MP in industrial and infrastructure applications where its combined breaker/relay portfolios overlap with MP's supplementary protectors.
- Schneider Electric: Schneider Electric is a major manufacturer of electrical distribution and circuit protection equipment serving industrial, commercial and OEM segments. It competes with MP in industrial control panels and OEM power distribution applications where buyers consider full-portfolio suppliers.
- Littelfuse: Littelfuse is a broad incumbent in circuit protection (fuses, breakers, semiconductor protection) serving automotive, industrial and electronics markets. While not purely focused on thermal breakers, it overlaps MP's industrial and truck/RV end-markets and is a meaningful competitor in DC protection components.
Direct peers
- Blue Sea Systems: Blue Sea Systems designs and manufactures marine electrical circuit protection including high-amperage breakers and switchgear. MP explicitly positions its Series 17/19/87 as drop-in replacements for Blue Sea products, and they compete head-to-head in marine ABYC-compliant DC circuit protection.
- Carling Technologies: Carling Technologies manufactures circuit breakers, switches and PDUs for marine, on-/off-road vehicle, and industrial applications. It overlaps MP's specialty vehicle, marine and high-amperage DC breaker product lines with comparable amperage ranges.
- Sensata Technologies (Klixon): Sensata's Klixon brand is one of the original thermal circuit breaker product lines and competes directly with MP across thermal, aviation, and industrial overcurrent protection. MP cites Klixon as a drop-in replacement target, confirming their direct overlap in thermal breaker technology.
- E-T-A Circuit Breakers: E-T-A is a specialist manufacturer of thermal, magnetic and electronic circuit breakers for industrial, vehicle and renewable energy applications. It is a like-for-like niche player competing with MP in thermal/hybrid breaker technology and custom-engineered protection solutions.
- Schurter: Schurter produces circuit protection devices including thermal and resettable breakers alongside a broader component portfolio. It competes with MP in industrial-grade supplementary protectors and custom OEM circuit protection.
- Eaton Bussmann: Eaton's Bussmann series is a leading industrial and vehicle circuit protection brand. MP markets its Series 17 as a drop-in replacement for Bussmann, and Bussmann competes in nearly every category (marine, truck, industrial) that MP serves.
