Siemens 3TX4 701-0AN1 is an OFF-delay device (Ausschaltverzögerer) designed to be used with Siemens 3TX4 contactor relays. Rated for 230 V AC at 50/60 Hz, it provides a selectable off-delay time of 0.6 seconds or 1.2 seconds, enabling controlled de-energization of the contactor coil after input power is removed. This accessory integrates with compatible 3TX4/3TH contactor assemblies to extend hold time in motor control circuits, supporting applications such as pumps, conveyors, and fans where a brief de-energization delay is required. By pairing the off-delay timer with the contactor, you can achieve a safe, orderly shutdown sequence without abrupt stopping.
