Curtis Industries Companies

What Curtis Industries Companies does

Curtis Industries Companies, founded in 1933 and headquartered in Milwaukee, Wisconsin, is a privately held manufacturer of standard and custom electrical components operating under the holding company Powers Holdings, Inc. The company produces terminal blocks (barrier, PCB, DIN rail), EMI/RFI power line filters (single-phase, three-phase, DC, medical, and military grades), custom injection- and transfer-molded electrical components, and through its Tri-Mag, LLC division, medical-grade external power supplies. A second sub-brand, Filter Networks, sells MIL-spec and ITAR-compliant filter products. Manufacturing is split between the Milwaukee headquarters facility and Curtis de Mexico in Nogales, with reported capabilities in plastic injection molding, transfer molding, metal stamping, in-house fabrication, and an in-house screen room for FCC/CISPR pre-compliance testing.

The business model is predominantly B2B hardware sales through a multi-tier channel. Curtis ships standard products through broad-line electronic component distributors (Digi-Key, Heilind, Master Electronics, Beyond Components, and others) that cover all 50 US states plus international markets in Mexico, Canada, Puerto Rico, the Dominican Republic, and South America. Custom design and prototyping services, including 1-2 week custom filter turnaround, are sold directly via manufacturer representatives and supported by an in-house engineering team. Pricing is quote-based for custom work and not publicly disclosed; the company cites 99.9% product reliability, >98% on-time delivery, and industry-unsurpassed first-pass yield on new designs as operational differentiators.

Curtis targets industrial, instrumentation, power supply, telecom, medical, commercial, appliance, machinery, aerospace, and military end markets, with stated relationships with Global 1000 organizations. Certifications include ISO 9001:2015, ITAR, UL, CSA, TUV, RoHS, REACH, CE, MIL.F-15733, and MIL-STD-220A. The company is privately held with no disclosed funding rounds, no public revenue figures, and no executive team visible in the source data; the most recent externally observable product and operational milestones date to 2020.

Direct peers

• Molex: Global manufacturer of electronic interconnect solutions including terminal blocks, PCB headers, and connectors. Molex is one of the legacy terminal block brands whose discontinued products Curtis actively cross-references, indicating direct product and customer overlap.
• TE Connectivity: Major manufacturer of terminal blocks (including the legacy Buchanan brand that Curtis cross-references), connectors, and electronic components. TE Connectivity competes head-to-head with Curtis in barrier terminal blocks and PCB terminal blocks across industrial and commercial markets.
• Weidmüller: Manufacturer of terminal blocks, industrial connectors, and electronics for power, signal, and data transmission. Weidmüller is a direct competitor to Curtis in industrial terminal blocks and shares a similar customer base in machinery, energy, and process industries.
• Astrodyne TDI: Manufacturer of EMI/RFI filters and power supplies for industrial, medical, military, and semiconductor applications. Astrodyne TDI directly overlaps with both Curtis's filter business and Tri-Mag's power supply offerings, especially in medical-grade and military-spec segments.
• Schurter: Specialist manufacturer of EMI/RFI filters, power entry modules, and circuit protection components for industrial, medical, and audio applications. Schurter competes head-to-head with Curtis's EMI/RFI filter portfolio, particularly in single-phase, medical-grade, and power entry module segments.
• WAGO: Specialist in spring-pressure terminal blocks, interconnection systems, and automation products. WAGO competes directly with Curtis in terminal blocks (especially PCB and DIN rail) and offers a similar mix of standard and customized industrial interconnect solutions.
• Phoenix Contact: Global market leader in industrial terminal blocks, PCB connectors, and surge protection. Phoenix Contact competes directly with Curtis in industrial terminal blocks and offers overlapping custom-engineering capabilities, but at substantially larger scale with broader global sales coverage.
• Eaton (Marathon Special Products): Eaton's Marathon Special Products division produces terminal blocks and power distribution blocks, including the legacy Kulka brand that Curtis cross-references. Eaton competes directly with Curtis in barrier terminal blocks and industrial power interconnect.

Broad incumbents

• Delta Electronics: Large global manufacturer of power supplies, EMI filters, and industrial automation components. Delta competes with Curtis in both power supplies and EMI filtering, but operates as a broad incumbent across many adjacent power electronics categories rather than focusing on Curtis's specialty niches.
• TDK-Lambda: Global manufacturer of AC-DC and DC-DC power supplies, EMI filters, and related components. TDK-Lambda competes with Curtis's Tri-Mag division on power supplies and with Curtis/Filter Networks on EMI filters, but at much larger scale and with broader industrial customer coverage.
