The Schneider LADR46 is a time delay auxiliary contact block designed for use in control circuits. As part of the TeSys D range, this component is engineered to enhance the functionality of control relays by providing an off delay timing feature. It is equipped with 1 Normally Open (NO) and 1 Normally Closed (NC) contact, with connections made via lugs-ring terminals for secure and reliable wiring.
With a rated insulation voltage of 600V according to UL standards and 690V in compliance with IEC 60947-5-1, the LADR46 ensures compatibility with a wide range of operational voltages up to 690V AC at frequencies between 25 and 400 Hz. The conventional free air thermal current is rated at 10A at 60°C, and the device can handle a making capacity of 140A AC and 250A DC, with permissible short-time ratings as specified in the datasheet.
The LADR46 is designed for front mounting and offers a time delay range of 10 to 180 seconds, with a minimum switching current of 5 mA and a minimum switching voltage of 17V. The non-overlap time ensures there is no overlap between NC and NO contacts during energisation and de-energisation, maintaining a clear switching state.
Constructed to withstand normal environmental conditions, the LADR46 maintains its performance within an ambient operating temperature range of -5 to 60°C and is suitable for use at altitudes up to 3000 metres without derating. It adheres to international standards such as IEC, BS, EN, VDE, and NF C, and holds product certifications from UL and CSA. The IP2x degree of protection as per VDE 0106 and the protective treatment conforming to TH IEC 60068 ensure the durability and reliability of the component in various industrial settings.
The LADR46 is a Green Premium product, reflecting Schneider's commitment to sustainable development and compliance with environmental regulations, including the EU RoHS Directive. This component is mercury-free and comes with a clear environmental disclosure through its Product Environmental Profile.
In summary, the Schneider LADR46 auxiliary contact block is a robust and reliable component for time-delayed switching in control circuits, offering precise timing adjustments, compliance with international standards, and a focus on environmental sustainability.
