Tower Manufacturing Corporation

What Tower Manufacturing Corporation does

Tower Manufacturing Corporation is a privately held, founder-owned manufacturer of electrical safety devices and electromechanical components, established in 1957 in Providence, Rhode Island by Louis Shatkin. The company's core portfolio centers on ground-fault and leakage-current protection devices: Ground Fault Circuit Interrupters (GFCIs) with auto/manual reset and 4–6mA Class A trip thresholds; Appliance Leakage Current Interrupters (ALCIs) for portable appliances; Leakage Current Detection Interrupters (LCDIs) for shielded-cord applications such as portable ACs and PTACs; Equipment Leakage Current Interrupters (ELCIs) with 10–100mA trip levels for equipment-fire protection; and Equipment Ground Fault Protective Devices (EGFPDs). Complementing the safety-device line, Tower manufactures electromechanical components — thermostats (12.5A–15A, slow or snap action), rotary switches (up to 13A, 100+ circuit configurations), slide/rocker/toggle switches, 120V AC buzzers, overload-protection quad-box power units, custom PCBAs, and coil/toroidal windings and solenoids. Over 20 patents have been accumulated under the founder's direction, and an on-site UL-certified lab in Rhode Island accelerates qualification testing witnessed by UL and cUL staff. VDE approvals support European market access for thermostats and rotary switches.

The company operates a fully OEM-embedded, direct B2B go-to-market: it sells exclusively to Original Equipment Manufacturers, developing custom or modified designs that integrate into customers' final products within tight timeframes. Four vertical segments are served — Construction, Commercial & Industrial, OEM Safety Products (primary), and Residential — across Fortune 500 customers in appliance manufacturing, HVAC, construction, and power tools. Pricing is quote-based and not publicly disclosed; sales are conducted through a dedicated sales team ([email protected], 401-467-7550). The company holds active memberships in UL's 1699 STP committee (LCDI/AFCI), NEMA, NFPA, AHAM, NEC code development, and maintains ongoing engagement with the CPSC, providing advance visibility into regulatory changes.

Manufacturing is split across two facilities: a headquarters and engineering site in Providence, RI, and an ISO 9001:2008-certified, ROHS-compliant facility in Shenzhen, China, with approximately 250,000 sq. ft. of manufacturing space and roughly 3,000 production workers. Sales and purchasing offices in Hong Kong and Taiwan support international OEM customers and procurement. Total firmographic headcount is reported in the 1,001–5,000 range; revenue is not publicly disclosed.

Products and services

• GFCI (Ground Fault Circuit Interrupter) Electrical safety device that detects ground faults and interrupts circuit power to prevent electric shock and fire hazards. Available in multiple form factors including inline, adapter, plug-in, extension cord, and user-replaceable models in 15 and 20 Amp ratings at 120VAC with automatic and manual reset options. Trips at 6mA or more but not less than 4mA (Class A) with open neutral and grounded neutral protection.
• LCDI (Leakage Current Detection Interrupter) Power cord safety device that uses shielded power conductors to detect cord breakage and interrupt electricity flow, providing protection against personal electrocution or fire due to power cord damage. Required by UL for portable ACs, window ACs and PTACs.
• ALCI (Appliance Leakage Current Interrupter) Safety device for portable appliances such as bathroom heaters, carpet cleaners, and hair dryers. Senses current imbalance and trips when there is a ground fault current of 6mA or more but not less than 4mA. UL Recognized Components marked 'UR'.
• ELCI (Equipment Leakage Current Interrupter) Fire protection device similar to GFCI but with higher trip level (10mA-100mA) designed to protect equipment from electrical fires rather than personnel from shock, in environments with low probability for personnel contact. All Tower ELCIs are UL and cUL approved.
• EGFPD (Equipment Ground Fault Protective Device) Equipment protection device similar to ELCI but approved under different test standards, limiting equipment damage from excessive ground fault currents.

• Slide, Rocker, and Toggle Switches Mid-sized to miniature non-illuminated snap-in switches. Rocker switches (12A-16A) for on/off applications; slide switches up to 13A for medium duty; toggle switches for rugged construction applications.
• Overload Protection (Quad Box) 4-outlet power box with built-in lighted master on/off switch and circuit breaker protection. Rated at 15A/1875W with 8-foot 14-gauge grounding cord. Custom options include housing, outlet cover, and power cord colors and lengths.
• Thermostats Standard or mini-size thermostats in slow or snap action types. Standard size rated at 15A for heaters and commercial cooking; mini-size at 12.5A for window fans, warming trays, and irons. VDE approved for European markets.
• Buzzers Electromagnetic type 120V AC buzzers for industrial and commercial applications. Used for tip over, end of cycle, or event failure alarms in small household appliances, washers, dryers, and alarm systems.
• Custom PCBA High-volume assembly process for small to medium single or double-sided boards and mixed technology. Supports thru-hole and RoHS/Lead-Free Surface Mount Technology (SMT) lines with wave solder equipment for OEM partners.
• Custom Windings & Solenoids Coil and toroidal windings and assemblies of various sizes. Equipment accommodates various wire gauges and bobbin sizes, including large solenoids that do not require encapsulation.
• Custom GFCI Custom-designed GFCI products for OEM integration, offering manual and automatic reset in various form factors, 15 and 20 Amp @ 120VAC, in corded, user-replaceable, or panel mount configurations.
