What Shallco does
Shallco, Inc. is a privately held, US-headquartered manufacturer founded circa 1970, specializing in precision rotary switches, relays, and battery disconnect systems for power generation, industrial, transportation, and — more recently — data center applications. The company designs and produces its products in the USA, with a portfolio organized across branded series including Series 16, Series 26, SN (cam switches), BR (bi-stable latching relays), MR (mono-stable relays), LT (lock-out/tag-out relays), 500/502/503/601 (battery disconnects), and DutySafe (duty-cycle protection breakers). Current ratings span 10A through 300A across AC and DC, with operating range down to -40°C, IP67/IP65 sealing on selected products, and mechanical life of 25,000 to 100,000 operations depending on series. Technical differentiation rests on a patented Load Monitoring Disconnect (US Patent 11,196,245) using a time-to-trip curve, bi-stable latching relay architecture using permanent magnets, and a proprietary Lock-Out Tag-Out function. The product set is certified to UL 508, cUL, CE, IEC 60947, IEC 60204, DIN EN 61058, C 22.2 No. 14, SAE-J1171 (marine ignition protection), and ISO 8846, with UL File #E208327 on record.
Shallco operates a hybrid B2B go-to-market combining direct sales — driven by separate RFQ flows for industrial and transportation products, a 1-800 sales line, and an "Ask an Expert" technical support channel — and channel distribution via authorized distributor connectorconcepts.com, which provides "Buy It Now" e-commerce fulfillment for standard catalog SKUs. Revenue is generated primarily through unit-priced hardware sales across two anchor verticals (Industrial/Power and Transportation/Automotive), supplemented by custom product design services for specialized applications. The website also presents a growing Data Center Power Products category positioning Series 26 Breaker Control Switches and Lockout Relays for AI data center deployment, alongside a Utility Switch Products category and an arc-flash protection sub-line.
The firm is small (headcount 11–50), operates exclusively from the United States with no international distribution disclosed, and emphasizes domestic, sustainable manufacturing and in-house custom design capability as core positioning. Recent activity across 2022–2025 — Load Monitoring Disconnect (2022), MR-Series voltage expansion (2023), BR-Series mounting refresh (2024), and Series 26 accessories plus the Double-Pole Battery Disconnect (2025) — indicates ongoing product-line development rather than capacity expansion, and no funding, M&A, or leadership changes have been disclosed.
