The LADT and LADR Time Delay Auxiliary Contact Blocks are designed to provide precise ON-delay and OFF-delay timing functions for contactors in industrial control applications. These auxiliary contact blocks are widely used in motor control panels, automation systems, HVAC, conveyors, pumps, and electrical switchgear where delayed switching is required for safety, sequencing, or load protection.
We at Haidery Electric supply original and compatible LADT & LADR time delay auxiliary contact blocks with multiple timing ranges to suit different industrial requirements.
Available Models & Timing Ranges
Available Models & Timing Ranges
ON-Delay Time Delay Auxiliary Contact Blocks (LADT Series)
ON-Delay Time Delay Auxiliary Contact Blocks (LADT Series)
LADT0 - ON Delay (0.3-3 Seconds)
Provides short ON-delay timing
Ideal for fast-response control circuits
Commonly used in interlocking and sequencing applications
LADT2 - ON Delay (0.1-30 Seconds)
Medium-range ON-delay timing
Suitable for motor start delays and automation logic
Ensures controlled energizing of circuits
LADT4 - ON Delay (10-180 Seconds)
Long ON-delay timing range
Used for heavy machinery, compressors, and sequential startup systems
Prevents sudden load impact
OFF-Delay Time Delay Auxiliary Contact Blocks (LADR Series)
OFF-Delay Time Delay Auxiliary Contact Blocks (LADR Series)
LADR0 - OFF Delay (0.3-3 Seconds)
Short OFF-delay timing
Ensures smooth de-energizing of circuits
Useful in safety and protection applications
LADR2 - OFF Delay (1-30 Seconds)
Medium OFF-delay timing
Allows equipment to run briefly after power cut
Common in ventilation and cooling systems
LADR4 - OFF Delay (10-180 Seconds)
Long OFF-delay timing
Ideal for industrial shutdown sequencing
Prevents abrupt stopping of heavy loads
