断路器ABB可为快速恢复运行条件（防止故障发生）, 并提供最好的解决方案，同时可提供最优的电气安装保护。从微型断路器到高分断能力的塑壳 / 空气断路器，ABB已经解决了在其范围内的所有技术问题。 今天，开发的电子平台正在控制和操作阶段，它将有助于更可靠和更先进的解决问题。
ABB Tmax断路器除了可用于常规的工业、建筑领域，亦可用于如煤矿、铁路隧道、太阳能、港口等特殊应用领域。Tmax断路器具有比市场上同类产品都高的性能尺寸比，可为用户提供更多的空间来进行电缆布线。
Tmax T2为同类产品中体积最小的电子式塑壳断路器，额定电流从4A开始，过载、短路电流曲线亦可精确整定。
Tmax T4-T5断路器在690V的电压下依然可以达到80KA的分断能力，电子脱扣器短路保护电流值可在1－12倍额定电流区间内连续可调，保证不同类型负载长距离配电的短路保护。
Tmax一体化的RC漏电和接地保护功能解决了诊断远端单相对地短路故障和小电流不脱扣的问题，一体化安装方式，体积紧凑，零序互感器内置，安装简便，测量精准。
保护电动机可选用 Tmax PR221MP/PR222MP＋A接触器改变了传统的使用断路器＋接触器＋热继电器的模式，实现了断路器和接触器一体化无缝连接，无需接继电器就可实现过载保护，省却电缆布线步骤，节省安装时间。同时，提供起动电流时间整定、相不平衡、触头热记忆等功能。
