Overview

The A334030 RELAY AS-SAFETY is a Doosan safety relay assembly designed for use across a broad range of Doosan electric and diesel forklifts. Relay assemblies like this one sit at the heart of the truck’s safety circuit, helping to control interlocks and protective switching so the truck operates only when safe conditions are met. When a safety relay begins to fail, operators may notice intermittent starting problems, warning faults or a loss of protective functions — replacing it promptly with the correct A334030 RELAY AS-SAFETY helps restore dependable, safe operation.

• B13/15/16R5 series electric trucks (SB1088)
• D20/25/30/32/33S-3 series diesel forklifts (SB1056/B33)

If you are unsure whether the A334030 for B13/15/16R5(SB1088) — or any other listed model — matches your truck, our team can verify fitment against your model and serial number before you order.

Quality and Reliability

As a Doosan component, the A334030 RELAY AS-SAFETY is intended to match the fit and function of the original relay installed on the factory line. A correctly functioning safety relay protects both the operator and the forklift’s electrical system, so choosing a replacement that matches the original part’s electrical ratings and connector configuration is essential. This relay assembly uses quality contacts and a robust housing designed to withstand the vibration, dust and temperature swings typical of warehouse, dock and yard environments.

Installation and Maintenance Tips

• Disconnect the battery (negative terminal first) before working on any electrical component.
• Compare the markings on your existing relay with the A334030 part number to confirm the match.
• Inspect the relay socket, terminals and wiring harness for corrosion, heat damage or loose contacts before fitting the new unit.
• Seat the relay fully and secure any brackets so vibration cannot work it loose.
• After installation, test all safety-related functions — including interlocks and start inhibit — before returning the truck to service.
• Always follow the procedures in your Doosan service manual, or have a qualified technician carry out the work.
