APIELE 12V 125A Continuous Solenoid Relay - Zinc-Plated 3-Terminal SPST for Winch, Golf Cart, Marine

APIELE Continuous Solenoid Relay is a heavy-duty 12V SPST starter relay built for sustained 125A operation and short bursts up to 300A, ideal for winches, golf carts, boats and other 12V systems.

This compact zinc-plated solenoid relay combines durable construction with high-current capability to replace many common OEM starter relays. It uses a copper-wound coil rated for high temperature and a galvanized housing to resist corrosion, while offering three-terminal wiring and bracket mounting for straightforward installation. The unit is designed for continuous use at rated current with the ability to tolerate short peak loads, and the spec list includes several cross-reference part numbers for easy replacement.

How much current can this relay handle and for how long?

The relay is rated for a continuous working current of 125A at 12V and can withstand temporary peaks up to 300A for short intervals (up to around 60 seconds). It is intended for intermittent heavy loads rather than prolonged high-current duty to avoid overheating. Follow recommended wire gauges and protective devices to ensure safe operation.

• Continuous current: 125A at 12V DC
• Short-term peak tolerance: up to 300A (approx. 60 seconds)
• Coil power: 10.2W with 14Ω resistance
• Recommended fusing/circuit breakers by wire gauge included

What are the electrical and mechanical specifications I should know?

This is a single-pole, single-throw (SPST) normally open relay designed for 12V DC systems. It uses a high-temperature copper coil and a corrosion-resistant zinc-plated shell, and it mounts via a bracket with pre-drilled holes to simplify replacement in many vehicles and equipment housings.

• Type: SPST, 1NO (normally open)
• Rating: 12V DC, coil 14Ω, 10.2W
• Mounting: bracket holes spaced 2-13/64" on center (holes 5/16" x 19/32")
• Terminals: three main terminals for power and control wiring

Which applications and OEM part numbers does it replace?

This relay is suitable for starter, winch and auxiliary high-current switching in golf carts, marine projects, utility vehicles and similar 12V systems. The listing cross-references many common replacement numbers so you can match it to existing equipment quickly.

• Common uses: winches, starters, golf carts, marine electrical systems
• Cross-reference numbers: 1114240, 1114241, 1114538, 97240-X, 70091714 and others
• Easy drop-in replacement when dimensions and terminal layout match

How should I wire and protect this relay for safe operation?

Choose wire and overcurrent protection based on expected current. Thicker wire and properly sized fuses or circuit breakers reduce voltage drop and prevent overheating. The relay documentation suggests specific wire gauges and protective device ratings for common load ranges.

• Use 16–18 AWG with a 5A fuse for low-current control circuits
• Use 10 AWG with a 30A circuit breaker for moderate loads
• Use 8 AWG with a 50A breaker for heavier auxiliary circuits
• Do not subject the relay to continuous operation at peak currents to avoid fire risk

Who is this for: Technicians, hobbyists and vehicle owners who need a rugged, direct-replacement 12V solenoid relay for starters, winches, golf carts and marine accessories will find this APIELE unit useful. It suits those looking for a compact, corrosion-resistant relay with clear mounting points, high-temperature coil construction and compatibility with common OEM part numbers. If your application requires prolonged continuous currents above the rated 125A, consider a higher-rated contactor or active cooling to protect the relay and wiring.
