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.
