Reviews
James Whitmore
I’ve used Potter & Brumfield electromechanical relays in commercial HVAC retrofits for over a decade, and they’ve consistently proven themselves under demanding conditions. The coils run cool, the contacts hold up without pitting, and replacements are easy thanks to standardized footprints. In multiple rooftop unit installations, their relays outlasted competing models by years, reducing callbacks and maintenance costs dramatically.
Sandra McMillan
My automation panel builds rely heavily on P&B solid-state relays, especially the SSR3 line, and the difference in noise and performance is night and day compared to mechanical alternatives. The silent operation is ideal for indoor and laboratory environments, and I’ve routinely run them near their rated limits without thermal issues. The screw terminals and compact footprint make wiring clean, which my clients always appreciate when reviewing control cabinet layouts.
Robert Delgado
Working in industrial safety systems, I regularly specify P&B time delay relays and circuit protection components. Their delay relays maintain incredibly stable timing even in high-vibration environments, which is critical for our sequencing interlocks. The thermal/magnetic breakers have also saved us from costly motor damage more than once, tripping exactly as expected during overload events. I trust them enough to use them in every new safety controller package we deploy.
Potter and Brumfield FAQ
What industries commonly use Potter & Brumfield relays?
Potter & Brumfield relays are widely used in HVAC systems, industrial automation, appliances, security systems, and computer peripherals where reliable switching and timing are critical.
What is the difference between electromechanical and solid-state relays?
Electromechanical relays use physical contacts to switch circuits and are ideal for high-current loads, while solid-state relays (SSRs) operate electronically, offering silent operation, fast switching, and long life without mechanical wear.
How do I choose the right relay for my application?
Select a relay based on load type, voltage, current rating, switching speed, environmental conditions, and mounting requirements. Consult datasheets to match relay specifications to your system’s needs.
Can Potter & Brumfield relays handle high-current applications?
Yes, many models, like the T92 power relays and SSR3 solid-state relays, are designed to handle currents up to 50A and voltages up to 480VAC, making them suitable for heavy-duty industrial and HVAC applications.
Where can I purchase Potter & Brumfield products?
Products are available through electronics distributors such as Mouser, Digi-Key, and TE Connectivity’s official platform. Contact TE Connectivity for regional sales support if needed.
How do I know if a relay is compatible with my PCB or panel?
Check the relay’s footprint, mounting type, voltage, and current ratings in the datasheet. Most P&B relays specify whether they are suitable for PCB or panel mounting.
What maintenance is required for these relays?
Electromechanical relays may require periodic inspection for contact wear, while solid-state relays are generally maintenance-free but should be monitored for overheating or voltage spikes.
Can Potter & Brumfield relays be used in automated timing sequences?
Yes, the time delay relays are specifically designed for automation and timing applications, providing precise and reliable delay functions in control systems.
