With a peak transient capability of 300A and a recommended continuous use under 150A, it replaces a wide range of OEM starter solenoids and uses durable 180°C copper coil winding to withstand high-heat starts. The nickel finish helps prevent corrosion and keeps contact surfaces bright, while the normally-open (NO) contacts and single-pole single-throw (SPST) design make it straightforward to install in starter circuits.\u003c\/p\u003e\n\n\u003ch3\u003eWhat electrical specifications should I expect from this solenoid?\u003c\/h3\u003e\n\u003cp\u003eThe solenoid features a 14Ω coil resistance and an effective coil capacity of 10.2W at 12VDC.

Technicians, fleet owners, and DIYers who maintain golf carts, small marine craft, ATVs, or winches will find this MaySpare solenoid a practical replacement when a reliable, corrosion-resistant starter relay is needed. It’s suited to projects that require a simple SPST starter action with strong transient current capability, provided users respect the duty-cycle limits and mounting specifications. If your application demands continuous heavy current or sustained engagement, consider a contactor rated for continuous duty or contact us for alternative recommendations.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Can this solenoid handle continuous 300A loads?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: No. 300A is a transient peak; continuous operation should be kept below 150A to avoid overheating.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Is the solenoid corrosion-resistant for marine use?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Yes.
