Dold Monitoring Relay 3 Phase 0.8 to 1.1 UN Monitor Range DPDT Contact Configuration DIN Rail Mount BA9041

Dold BA9041 Monitoring Relay is a high-quality industrial electrical relay designed to monitor the phase sequence and voltage presence in three-phase electrical systems. The device recognizes the phase sequence L1 - L2 - L3 of a three-phase network, preventing incorrect rotational directions in motors and machinery.

This relay features a DPDT (Double Pole Double Throw) contact configuration with a switching voltage of 230V AC and a contact current of 5A. It mounts easily on DIN rails, compliant with DIN 43 880 standards, allowing for standardized panel installations.

The BA9041 model monitors voltages in the range of 0.8 to 1.1 UN and provides reliable phase sequence failure and phase absence detection. When voltages are correct and in sequence, the output contacts switch to the operative position, and a green LED indicator lights up to signal correct operation. If the voltage in any phase falls below 60% UN, the relay de-energizes as per IEC 255 standards, providing reliable protection.

Constructed with robust orange housing, this relay carries multiple international standards and approvals, ensuring safety and durability in industrial environments. Its IP20 and IP40 ratings protect against solid foreign objects and limited ingress of dust, suitable for indoor automation systems.

Dimensions of 45 mm width, 119.8 mm length, and 73.2 mm height provide a compact footprint, ensuring efficient use of space in control panels. The operating temperature range from -60°C to +60°C supports reliable functioning in varying industrial climates.

This monitoring relay is ideal for industrial automation, electrical supply monitoring, water treatment plants, HVAC systems, manufacturing plants, and other commercial applications requiring phase monitoring and protection.
