EHDB130 ABB heavy-duty DC contactor for elevator & industrial drive dynamic braking systems, original electrical spare part, full insulation & contact performance test with 12-month global warranty for elevator, servo drive cabinet maintenance replacement

Product Overview

• PN: EHDB130｜Brand: ABB｜Series: EHDB DC Contactor Series｜Type: 3-Pole Heavy-Duty DC Drive Contactor

• Definition: ABB EHDB130 is a high-current DC dedicated contactor, mainly used in elevator traction systems, industrial servo drives, crane dynamic braking circuits, and DC motor control occasions. It is responsible for switching DC main circuit, dynamic braking loop, motor power on/off control, and can withstand frequent high-current make-and-break operations, widely used in elevator, metallurgy, port machinery and other heavy-load equipment, a core spare for contact ablation, coil burnout, main circuit failure overhaul and replacement

Core Features

1. Three-pole main contact design, rated working current 130A, maximum withstand voltage up to 600VDC, specially optimized for DC arc extinction, equipped with independent arc extinguishing cover to quickly break DC arc and avoid contact welding failure caused by frequent high-current switching.
2. Standard configuration with 1 normally open + 1 normally closed auxiliary contact, expandable up to 8 auxiliary contacts (4NO+4NC), which can feed back contact closing status to PLC/DCS for interlock safety protection and equipment fault monitoring.
3. Adopts high-temperature sealed electromagnetic coil, supports wide control voltage range (85%~110% rated voltage), can be matched with AC/DC control coils of different specifications, with strong anti-voltage fluctuation capability to adapt to unstable industrial power grid environment.
4. Double-break contact structure, silver alloy contact material, anti-ablation, anti-welding, suitable for frequent start-stop working conditions such as elevator up and down running, dynamic braking of frequency converters.
5. Standard 35mm DIN rail mounting structure, touch-safe fully enclosed terminal design to prevent accidental electric shock; detachable arc extinguishing cover, convenient for on-site contact wear inspection and maintenance.

6. Supports mechanical interlock accessories installation, can form reversible forward and reverse control groups to prevent short-circuit risk of DC main circuit caused by simultaneous closing of positive and reverse contactors.
