Frequently Asked Questions
Q: What are the electrical specifications for the 36V electric horn 902379?
A: This horn is rated for 36VDC nominal operation with an operating range of 36 to 48VDC. It features a 2-terminal post connection and produces 105 dB sound output at rated voltage. The steel body construction provides durability in industrial environments.
Q: Which lift truck brands does horn 902379 fit?
A: This horn is designed for Mitsubishi and Caterpillar electric lift trucks. OEM part numbers are MB902379 for Mitsubishi and CT902379 for Caterpillar. It is a 3-7/8 inch diameter device compatible with standard electric truck horn mounting.
Q: Are there cross-reference or equivalent part numbers for 902379?
A: Yes. Cross-reference numbers include CT0902379, CATERPILLAR 0902379, CATERPILLAR/TOWMOTOR 0902379, and TOWMOTOR 0902379. All reference the same 36V horn assembly with identical specifications and fitment.
Q: Can this horn operate on voltages outside the 36-48VDC range?
A: No. This horn is rated for 36 to 48VDC only. Operating below 36VDC reduces output volume and can damage the solenoid. Operating above 48VDC voids the warranty and risks failure. Verify your truck electrical system voltage before ordering.
Q: What does 105 dB sound output mean for this horn?
A: 105 dB is the measured acoustic output at rated 36VDC. This meets industrial safety standards for audible warning signals on lift equipment. Output may vary slightly depending on mounting surface and ambient conditions.
