The Schneider LADR4 is a time delay auxiliary contact block designed to enhance the functionality of control relays and contactors within your electrical systems. This robust component offers a single normally open (NO) and a single normally closed (NC) contact, making it a versatile choice for various applications. It is engineered to provide an off delay timing range of 10 to 180 seconds, allowing for precise control in your circuitry.
Constructed to meet the high standards of the TeSys product range, the LADR4 ensures compatibility with TeSys D CAD, TeSys D LC1D, TeSys F LC1F, and TeSys F CR1F, among others. This ensures seamless integration with existing setups for a wide range of industrial applications. The contact block is designed for front mounting, facilitating easy installation and maintenance.
Rated for operational voltages up to 690 V AC at frequencies between 25 and 400 Hz, the LADR4 is equipped to handle substantial electrical loads with a rated insulation voltage of 690 V, conforming to IEC 60947-5-1 standards. It also boasts a conventional free-air thermal current of 10 A at 60°C, demonstrating its capability to sustain regular operation without overheating.
The LADR4's mechanical durability is proven with a rating of 5 million cycles, ensuring long-term reliability and performance. The minimum switching current and voltage are rated at 5 mA and 17 V, respectively, which allows for the switching of low-level electrical signals, making it suitable for a variety of control logic scenarios.
This contact block is a Green Premium product, reflecting Schneider Electric's commitment to sustainable development and compliance with environmental regulations. It is mercury-free and adheres to the EU RoHS Directive, ensuring that it is free from certain hazardous materials and is suitable for safe disposal within European Union markets.
The LADR4's compact dimensions and screw clamp terminals make it a practical choice for space-constrained environments, while its dark grey colour and IP20 degree of protection ensure it blends into industrial settings and is protected against solid objects larger than 12.5 mm.
In summary, the Schneider LADR4 time delay auxiliary contact block is a reliable and eco-friendly component that offers precise timing control, robust performance, and compatibility with a range of TeSys products, making it an essential part of your industrial control systems.
