  • Do fire pumps need thermal relay protection

    Do fire pumps need thermal relay protection

    Provide Thermal Protection Devices: Use temperature sensors, overload relays, or thermistors integrated with the controller to automatically shut down the pump in case of overheating. That is why fire pump motor thermal protection matters so much. Figure 01 A general philosophy for most electrical installations is to provide circuit protection that will disconnect power before allowing the conductors to overheat and become damaged. However, overheating is one of the most common and dangerous issues that can compromise performance, damage equipment, or even cause system failure at critical moments. Preventing. UL/FM fire pump controllers, or “listed” fire pump controllers, are guided by requirements in NFPA 20 and NEC regarding their components, as well as considerations for their installation. Most fire pump controllers today are “service entrance rated,” which means they can be connected directly to. Isolating switches must be readily accessible to allow for prompt energizing of the fire pump motor circuit. PTC thermistor relays with ATEX approval also protect.
