PFCL201C 50KN工控机器人备件
短路和过载。过载保护通过使用LZM断路器实现，该断路器具有可设置的、电流相关的、延迟过载释放。短路保护由可调瞬时脱扣器提供，该脱扣器在25ms内断开主触点。短路总打开时间将电缆的温升限制在最小值。表中显示了短路期间断路器可靠保护的最小导线横截面。（工作电压UN=415V）如果断路器安装点的预期故障电流非常高，通常使用LZMN限流断路器。如果LZMB（C）开关的故障等级太高，则价格合理的替代方案是在LZMB（B）标准断路器的上游安装LZMN限流断路器。该表显示了LZMN与LZMB（C）结合使用的限流断路器，用于在具有高shor 8系统的网络位置提供保护，LZM1系统的线路保护，LZM2跳闸时间的线路保护设置范围公差t 1断路器技术数据LZM…1，LZM…2，LZM..3，LZM.4额定不间断电流最大160 A LZMB1 LZMC1 LZMN1通用标准IEC/EN 60947防直接接触手指和手背防护符合VDE 0106第100部分气候防护湿热，恒定，符合IEC 60068-2-78湿热，符合IEC 60068-2-30的周期性环境温度存储°C–25…+70操作°C–30…+70机械抗冲击性（IEC/EN 60068-2-27）20（半正弦冲击20 ms）符合VDE 0106第101部分和第101/A1部分的安全隔离辅助触点和主触点之间的V AC 500辅助触点之间的AC 300安装位置垂直和所有方向的90°输入电源按要求的防护等级操作控制区域内的设备：IP20（基本防护等级）外壳，绝缘外壳：IP40，带门耦合旋转手柄：IP66端子隧道端子：IP10相位隔离器和条形端子：IP00断路器额定冲击耐受电压Uimp主触点V 6000 6000 6000辅助触点V 6000 60006000额定工作电压Ue V AC 440 440过电压类别/污染等级III/3 III/3额定绝缘电压Ui V 690 690 690开关容量额定短路闭合容量240 V I cm kA 63 121 187 400/415 V I cm
Short circuit and overload. Overload protection is achieved by using LZM circuit breakers, which have settable, current dependent, delayed overload release. Short circuit protection is provided by an adjustable instantaneous release, which disconnects the main contact within 25ms. The total short-circuit opening time limits the temperature rise of the cable to a minimum. The table shows the minimum conductor cross-section for reliable protection of the circuit breaker during short circuit. (Working voltage UN=415V) If the expected fault current at the installation point of the circuit breaker is very high, LZMN current limiting circuit breaker is usually used. If the fault level of LZMB (C) switch is too high, the affordable alternative is to install LZMN current limiting circuit breaker upstream of LZMB (B) standard circuit breaker. This table shows the current limiting circuit breaker used in combination with LZMN and LZMB (C), which is used to provide protection at the network location with high shor 8 system, line protection of LZM1 system, line protection setting range tolerance of LZM2 tripping time t 1 Technical data of circuit breaker LZM... 1, LZM... 2, LZM.. 3, LZM 4 Rated uninterrupted current Maximum 160 A LZMB1 LZMC1 LZMN1 General standard IEC/EN 60947 Protection against direct contact with fingers and back of hand complies with VDE 0106 Part 100 Climate protection Damp heat, constant, complies with IEC 60068-2-78 Damp heat, Periodic ambient temperature storage according to IEC 60068-2-30 ° C – 25...+70 operation ° C – 30...+70 mechanical impact resistance (IEC/EN 60068-2-27) 20 (half sine impact 20 ms) Safety isolation according to VDE 0106 Part 101 and Part 101/A1 AC 300 between auxiliary contacts and V AC 500 auxiliary contacts between main contacts Installation position 90 ° input power supply in vertical and all directions Operate equipment in the control area according to the required protection level: IP20 (Basic protection level) enclosure, insulated enclosure: IP40, Door coupling rotary handle: IP66 terminal Tunnel terminal: IP10 phase isolator and strip terminal: IP00 circuit breaker Rated impulse withstand voltage Uimp Main contact V 6000 6000 6000 Auxiliary contact V 6000 60006000 Rated working voltage Ue V AC 440 440 Overvoltage category/pollution level III/3 III/3 Rated insulation voltage Ui V 690 690 690 Switch capacity Rated short circuit making capacity 240 V I cm kA 63 121 187 400/415 V I cm
