Product Description

Dold IK9178 3AC50/60Hz 400V monitoring relay is a high precision device for monitoring three-phase electrical systems. Suitable for industrial and automation applications, it monitors direction of rotation and phase sequence within the voltage range of 0.8 to 1.1 UN at 400V AC supply. This relay mounts easily on a DIN rail and has a compact design with a width of 17.5 mm to fit in control panels.

The device includes an LED indicator that lights up when a clockwise rotation field is detected, assisting with quick diagnostics and safety checks. It can handle a contact current of 3A, making it reliable for control purposes in manufacturing, electrical substations, and HVAC systems. Operating temperature ranges from -60°C to +60°C ensure stable operation under harsh environmental conditions.

Constructed to meet rigorous standards such as IEC 60664-1, IEC/EN 61000 series, UL 94 V0 flammability, and DIN 46228, the IK9178 series guarantees performance and safety compliance. Its robust orange housing and DIN rail mounting conform to DIN 43 880, securing the relay firmly within industrial racks.

Monitors three-phase systems for phase sequence and rotation direction. Voltage monitoring range from 0.8 to 1.1 UN under 400V AC supply. DIN rail mount for simple integration in control panels. LED display for visual indication of clockwise rotation condition.

Contact current rated at 3A for control applications. Wide operating temperature range from -60°C to +60°C. Compliance with multiple IEC, EN, and UL standards. Durable orange housing manufactured to DIN 43 880 standard.

This monitoring relay is ideal for industrial, automation, safety, and electrical control applications where reliable three-phase system monitoring is critical. It supports preventive maintenance and protects equipment from phase failure or incorrect rotation.
