Product Description
The Dold IL9075.12/001 AC50-400Hz 400V is a Monitoring Relay designed for industrial and commercial electrical systems, providing reliable protection by detecting fuse failures in three-phase networks up to 440 V. Suitable for use in automation, manufacturing, and motor control applications, this relay ensures safety and operational continuity by signaling fuse failures even when loads are switched off.
With a DPDT contact configuration and mounting on a 35 mm DIN rail, it offers easy installation and integration into control panels. The device includes two LED displays and two changeover contacts to provide clear and immediate visual and switching responses for fault conditions.
Its advanced design allows operation without abnormal behavior in asymmetrical networks or systems with regenerative motors, thanks to features that ensure independence from rotational direction and a rest current principle maintaining an internal resistance over 1 MΩ.
Compliance with multiple international standards, including IEC and UL, guarantees high performance in harsh industrial environments, with minimum and maximum operating temperatures from -60°C to 60°C. This makes the relay suitable for a wide range of industrial, laboratory, automation, and electrical control applications.
The compact size (59mm length x 35mm width x 90mm height) makes it an ideal choice for control cabinets where space optimization is critical. Monitors fuse integrity in 3-phase electrical networks up to 440 V. Two LED indicators provide clear fault indication and status.
Short response time helps to protect motors and control equipment quickly. Designed to function reliably even with loads switched off. Suitable for all fuse types and sizes. Mounts securely on a 35 mm DIN rail for easy panel integration.
Complies with IEC/EN and UL standards ensuring robustness and safety. Ideal for industrial, automation, electrical distribution, and monitoring applications. EnvMart offers a wide assortment of relays and monitoring devices designed for diverse electrical and automation needs.
