LA1-DN22 Auxiliary Contact for Safe Contactor Control
The LA1-DN22 auxiliary contact extends the functionality of LC1D and LP1D series magnetic contactors, offering a 2NO/2NC configuration for complex commands in industrial and residential electrical panels. Compatible with a wide range of contactors, it ensures signaling and interlocking in control and protection circuits.
What you get with this product
- Extended compatibility — works with LC1D and LP1D contactors from 9A to 150A, eliminating the need for prolonged searching for suitable accessories
- Flexible 2NO/2NC configuration — allows for signaling, interlocking, and interverrouillage in installations with multiple motors or loads
- Quick installation on contactor body — mechanical attachment without additional screws, assembly in less than 2 minutes
- IEC compliance and international certifications — guarantees operational safety according to European electrical standards
- Durability in industrial environments — silver-cadmium contacts with reduced wear, resistance to frequent switching
- Reduced maintenance costs — can be replaced independently without dismounting the main contactor from the panel
How it works and how to install it
The auxiliary contact is mounted laterally on the body of the compatible magnetic contactor, using dedicated guides and clips. Once fixed, the 2NO and 2NC contacts switch simultaneously with the main contacts of the contactor, thus allowing for signaling, interlocking, or sequential control circuits. Connection is made via clearly marked terminals on the upper and lower sides of the module.
Installation requires disconnecting the power, mechanically fixing the auxiliary module to the existing contactor, and connecting the control wires according to the electrical diagram. No special tools are required, only a screwdriver for tightening the terminals.
Frequently Asked Questions
Does the LA1-DN22 contact fit my LC1D25 contactor?
Yes, the LA1-DN22 auxiliary contact is compatible with all LC1D and LP1D contactors between 9A and 150A, including the LC1D25.
What does 2NO/2NC mean and how do I use them?
2NO means two normally open contacts that close upon activation, 2NC means two normally closed contacts that open. You use them for light signaling, interlocking between contactors, or auxiliary commands.
Can I mount multiple auxiliary contacts on the same contactor?
Yes, LC1D contactors allow for the simultaneous mounting of two auxiliary contacts, one on each side, according to available space.
