Siemens Contact Block, 10A Current Rating, 1NO Contact - SIRIUS ACT Series - 3SU1400-1AA10-3BA0
Use this reliable contact block from Siemens to connect electrical circuits in your industrial system. Its simple snap-on design makes it straightforward to integrate into your circuitry, so it reduces installation time. As the unit is stackable, you can place multiple units on top of each other to save surface area. It's even possible to install the device in a slanted position, which comes in handy when space is limited. The patented holder features twist-prevention in order to stop the block from moving once it's installed.
• Tested to withstand the extreme environments commonly found in industry
• Self-holding function of the actuator when mounting allows a range to be set in order to prevent rapid switching when there are ripples in the current
What does 1NO mean?
The number signals the number of pairs of contacts and NO stands for 'normally open'. This means that the contact points will remain open until the switch is actuated. Essentially, the switch needs to be turned on in order to complete the circuit and start your machine or equipment.
