NettetThermistor Motor Protection Relay K8AK-TS/-PT Monitor Temperature Rise through Internal Motor Loss • Temperature, phase sequence, and phase loss monitoring with the DIN 22.5-mm-sized K8AK-PT Relays. • Side-by-side mounting of K8AK-PT Relays. • Specially designed for internal motor monitoring; no setting required. • As current-limiting devices for circuit protection, as replacements for fuses. Current through the device causes a small amount of resistive heating. If the current is large enough to generate more heat than the device can lose to its surroundings, the device heats up, causing its resistance to increase. This creates a self-reinforcing effect that drives the resistance upwards, therefore limiting the current. bubbling mud sound youtube
