TB521-ETH ABB塑壳断路器能够自动切断电流在电流超过跳脱设定后。塑壳指的是用塑料绝缘体来作为装置的外壳，用来隔离导体之间以及接地金属部分。塑壳断路器通常含有热磁跳脱单元，而大型号的塑壳断路器会配备固态跳脱传感器。其脱扣单元分为:热磁脱扣与电子脱扣器。
TB521-ETH ABB moulded case circuit breakers are able to automatically cut off the current after the current exceeds the trip setting. Moulded case refers to the use of a plastic insulator as the enclosure of the device, which is used to isolate the conductors from each other and from the earthed metal parts. Moulded case circuit breakers usually contain a thermo-magnetic trip unit, while larger models are equipped with a solid-state trip sensor. The tripping units are classified into: thermal magnetic tripping and electronic trippers.
