Overload Protection Sample Clauses
The Overload Protection clause establishes measures to prevent equipment or systems from operating beyond their safe capacity limits. Typically, this involves installing devices or implementing procedures that automatically shut down or limit operations when excessive loads are detected, such as circuit breakers in electrical systems or pressure relief valves in mechanical setups. Its core function is to safeguard both the equipment and personnel by minimizing the risk of damage, failure, or accidents caused by overloading.
Overload Protection. Since the intense heat caused by overload may seriously damage the motor, the consumer should install a device that will disconnect the motor if overload occurs. Fuses, thermal relays, or circuit breakers that are specifically designed to operate when excessive current occurs are the devices used for this purpose. Where the consumer receives three-phase service, such protective devices should be connected in all phases.
Overload Protection. In order to avoid current overload, which could lead to harmful overheating of the insulation or of the surrounding environment, a conduit, with operating current Ib and range Iz (Ib <= Iz), must be protected by a device having a rated current and (/1} conventional working current If such that these satisfy the conditions: The switches comply with IEC 23-3 and 17-5 and fulfill the second condition.
Overload Protection. This protection shall be provided by means of a load limiting system, comprising two load cells, whose outputs can be summed and amplified by suitable electronics. Under normal operating condition when the lifted lo ad is equal to or more than the safe working load the output from the summing amplifier shall be used to energize the tripping card relay. An audible warning device is provided indicating that overload is lifted. Load cells shall be protected against vibra tions and forces irrelevant to measured quantity. Load shall have identified linear force -voltage characteristics. Load cells shall be completely protected against dust, heat and rain and shall have overload capacity at least 50% of rated load as lateral l oadings. Performance accuracy : Weighing accuracy: 0.05% of rated load Overall accuracy : 3 to 5% of rated load. Enclosure : IP68 Weighing cabinet shall have regulated power supply uni t, evaluation unit, automatic tarring unit & display on front panel.
Overload Protection. All motors, including those rated below 0.5 kW, shall be protected by overload protections connected to all loaded phases and shall also have phase failure protection and be interlocked against automatic restarting. Overload protections for motors with long starting times and/or heavy loads must not be tripped during the starting process, unless the motor is otherwise protected against harmful temperature rise. A motor shall normally be provided with winding temperature monitoring of thermistor or equivalent type. A motor with speed control shall be provided with winding temperature monitor of thermistor or equivalent types. All overload protections, including thermistor relays, shall be provided with auxiliary contacts, one of which shall be connected directly to the actuating circuit of the contactor coil. The other auxiliary contact shall be used for overload indication and can be connected in sections in parallel, if considered advisable, either to the PLC input or directly to an indicating lamp if a PLC system is not used.
Overload Protection. Excessive peak current and average current must shutdown the unit before damage can occur
