Robertshaw

Robertshaw is a brand with a long history in the HVACR and industrial controls sector, originating in the United States and now operating as a global supplier of components for heating, ventilation, air conditioning, and refrigeration systems. The brand is widely recognized for its extensive range of controls, including thermostats, gas valves, ignition systems, pressure switches, and safety devices. Robertshaw products are designed for both OEM and aftermarket applications, with a focus on reliability and compatibility across multiple equipment brands. Key product families include commercial thermostats (e.g., digital WiFi wall thermostats with touch-screen controls and voice-enabled capabilities), universal and direct OEM replacement hot surface ignitors (silicon carbide and silicon nitride types with various lead lengths and voltage ratings), adjustable set-point air pressure switches (with manual reset and SPDT contacts, covering low-pressure ranges from 0.15 to 5 inches of water column), universal pilot assemblies (for natural gas and LP, including thermopile components), mechanical vibration sensor switches (SPDT, rated for 7 A at 460 V AC, with manual reset), and gas valves for HVACR systems. Robertshaw components are built to meet standard industrial specifications, with IP ratings and voltage tolerances appropriate for their intended environments—such as outdoor-rated vibration switches and hardwired ignitors for commercial furnaces. 3G Electric stocks over 230 SKUs of Robertshaw products, providing datasheets and logistics support for global procurement. The range covers applications from residential and commercial HVAC to industrial burner controls, with products available in multiple configurations (e.g., plug-in vs. hardwired connections, flat vs. round tips, 90° pilot assemblies). Technical buyers can expect consistent build quality across the line, with components designed for straightforward replacement and integration into existing systems. 3G Electric supports this line with detailed specifications and global shipping, enabling engineers and maintenance managers to source replacement parts or new installations without geographic constraints.

Frequently asked questions

Common questions about Robertshaw from 3G Electric.

What types of Robertshaw thermostats are available through 3G Electric?

3G Electric stocks Robertshaw commercial thermostats, including the RS10420T digital WiFi wall thermostat. This model supports heat and cool applications, features a touch-screen interface, auto-on-off fan settings, and voice-enabled smart capabilities. It is designed for programmable control in commercial environments. Other thermostat variants may be available; check the product listings for specific model numbers and specifications.

Are Robertshaw hot surface ignitors compatible with multiple OEM brands?

Yes, Robertshaw offers both universal and direct OEM replacement hot surface ignitors. Universal models, such as the 41-230 and 41-401, are designed to replace ignitors from brands like White-Rogers, with silicon carbide construction and flat tips. Direct OEM replacements, like the 41-428N, are specifically for Trane equipment and use silicon nitride. All operate at 120V AC, with lead lengths from 4.25 to 8 inches and either hardwired or plug-in connections.

What is the pressure range for Robertshaw adjustable set-point air pressure switches?

The Robertshaw 2374-509 adjustable set-point air pressure switch operates within a range of 0.15 to 5 inches of water column (in wc). It features a manual reset, SPDT contact configuration, and is rated for 28V DC. This switch is suitable for low-pressure sensing applications in HVACR systems, such as draft or airflow monitoring.

Can Robertshaw pilot assemblies be used with both natural gas and LP?

Yes, the Robertshaw Uni-Line 1820 pilot assembly (model 1820-009) is a universal unit compatible with both natural gas and LP. It includes a thermopile and features a 90° right configuration. This assembly replaces OEM part numbers like PG9 and is designed for straightforward installation in gas-fired equipment.

What are the electrical ratings for Robertshaw vibration switches?

The Robertshaw Series 366 vibration switch (model 366A0) is a mechanical sensor with SPDT contacts rated for 7 A at 460 V AC. It features a manual reset and is designed for outdoor-rated environments. This switch is used to detect excessive vibration in industrial equipment, such as pumps or compressors, and provides a reliable shutdown signal.

Does 3G Electric carry Robertshaw gas valves for HVACR systems?

Yes, 3G Electric stocks Robertshaw gas valves, such as the 700-456 model. These valves are used in HVACR systems for controlling gas flow to burners. Specific specifications, including inlet/outlet sizes and pressure ratings, are provided in the product datasheets. Contact 3G Electric for detailed compatibility information.
