Frequently Asked Questions
Q: What does the 123108 contact set fit?
A: The 123108 is a contact set rated SB350 2/0 (American Wire Gauge). It is designed for medium-duty electric lift truck control circuits. This part fits various Crown, Toyota, Raymond, and Yale lift truck models. Verify your equipment model before ordering.
Q: What is the difference between SB350 2/0 and SB350 3/0 contact sets?
A: The 123108 (SB350 2/0) and 123109 (SB350 3/0) differ in current capacity and wire gauge. The 2/0 handles smaller amp loads, while 3/0 is rated for higher amperage circuits. Use the contact set rated for your specific circuit amperage. Mismatched ratings cause overheating and failure.
Q: When should the 123108 contact set be replaced?
A: Contact sets typically last 2 to 4 years depending on switching frequency and arc erosion. Replace when contacts show visible pitting, the solenoid clicks but does not fully engage, or electrical resistance increases. Worn contacts increase heat and reduce circuit reliability.
Q: What causes contact set failure in the 123108?
A: Contact sets fail due to arc erosion from repeated switching cycles, moisture and corrosion, overload conditions, or undersized wire gauge for the circuit amperage. Heavy-duty applications and frequent on-off cycling accelerate wear.
Q: Is the 123108 compatible with SB350 3/0 circuits?
A: No. The 123108 (2/0) is not rated for 3/0 circuits and will overheat under higher amperage loads. Use SKU 123109 for SB350 3/0 systems. Installing undersized contacts causes failure and potential safety hazards.
