标准 IEC 60947-1, DIN EN 60947-1, IEC 60947-4-1, DIN EN 60947-4-1, IEC 60947-5-1, DIN EN 60947-5-1, 3TH42 和 3TH43 接触器式继电器适合在任何气候中使用。
可安全用指触摸，符合 EN 50274。 端子名称符合 EN 50011 关于其端子名称、识别号码和识别字母，3TH42/3TH43 接触器式继电器符合用于“特殊接触器式继电器”的 EN 50011 标准。
接触可靠性由于采用双断触点，在低电压和电流时可实现高接触稳定性，适合≥ 17 V电压时电流≥ 1 mA的固态电路。
先通后断接触 3TH42/3TH43 接触器继电器在具有先通后断功能的型号中可用（在 1 个常开和 1 个常闭触点之间先通后断）。 先合后断时间约1 ms。这不足以导致另一个接触器闭合。
如果先通后断导电通路串联，则可以创建一个瞬时接触元件；清除时间约为 1 ms。
浪涌抑制 3TH42/3TH43 接触器可以配备 RC 元件、变阻器、二极管或二极管组件（一个二极管与一个齐纳二极管组合），用于抑制开路浪涌。浪涌抑制器可以直接安装在线圈上（见附件）。
注意： 如果接触器线圈可防电压峰值 （干扰抑制二极管为 6 到 10 次；二极管组件为 2 到 6 次；变阻器为 2 到 5 ms），则 NO 触点的延迟断开时间和 NC 触点的延迟闭合时间会增加。
