Siemens Contact Block, 10A Current Rating, 1NC Contact - SIRIUS ACT Series - 3SU1400-2AA10-1CA0
Turn machinery on and off safely with this contact block from Siemens. It's easy to install as it has pre-drilled mounting holes, so it doesn't require any specialist tools. The screw terminals are straightforward to connect and provide reliable circuit connection, which helps to limit installation and maintenance time. The actuator has a self-holding function when mounting. This allows a control range to be set to prevent the relay from switching rapidly when there are ripples in the current. You can place multiple blocks in sequence as the unit is stackable, which is handy when space is limited.
• High-grade plastic construction is rugged and reliable for a long service life
• Possible to install in a slanted position, for versatility when mounting
• Wide operating voltage range between 5 to 500V on AC and DC circuits, for use in multiple applications
What does 1NC mean?
NC stands for normally closed, meaning the circuit will remain closed and allow current to flow unless the switch is activated. The number in front tells you how many pairs of contacts are in this switch. So 1NC means there is one pair of normally closed contact points in this switch.
