B-LINE 10250T45 – Frequently Asked Questions
1) What contact arrangement does the B-Line 10250T45 contact block have?
The 10250T45 is a special function block with two late opening normally closed contacts (2LONC). Late opening means both NC contacts break after the standard contacts in a stack, which is how you sequence a control circuit so one function drops out before another.
2) How many contact blocks can I stack on one 30.5 mm push button?
Up to 6 blocks can be stacked unless otherwise noted. That gives you room to combine the 2LONC late opening block with standard NO/NC blocks on the same operator when you need a staged sequence.
3) What type of wire terminals are on the 10250T45 block?
Pressure terminals. You strip the conductor and clamp it under the screw pressure plate, so no ring or fork lugs are needed for field wiring.
4) When would I use a late opening NC contact block instead of a standard NC block?
Use the late opening version when one circuit has to stay made slightly longer than the others on the same operator. A standard NC block breaks with the rest of the stack; the 10250T45's two NC contacts break after, so you can drop a holding or interlock circuit last. If you just need a plain break contact, a standard 10250T NC block is the simpler choice.
