2X 12V 5 Terminal Solenoid Relay Fit Prestolite 15-301 MRVB8 MBJ-4201 MBJ-4202

12V Solenoid Relay for Prestolite

This pack of two 12V 5-terminal solenoid relays serves as a direct electrical replacement for Prestolite 15-301 and cross-referenced models MBJ-4201 and MBJ-4202, providing reliable switching for high-current circuits.

Overview

This 12V 5 terminal solenoid relay is a heavy-duty electrical switch used to control a high-current load with a low-current signal, commonly found in starting or charging systems for vehicles and equipment. Each relay is designed to handle continuous 12V operation and features five spade terminals for standardized wiring. This two-pack offers an efficient solution for replacing worn or failed solenoids in your electrical system.

Built For Performance

• Rated for 12V DC continuous duty with high current capacity for reliable switching
• Five terminal design (typically 30, 85, 86, 87, 87a) for versatile wiring configurations
• Sealed casing protects against dust and moisture for long service life
• Interchangeable with Prestolite 15-301, MBJ-4201, and MBJ-4202
• Compact, robust construction suited for under-hood or chassis mounting

Fits These Machines

• for Prestolite systems using relay part 15-301
• for Prestolite systems using relay part MBJ-4201
• for Prestolite systems using relay part MBJ-4202

On-The-Job Use

• Use for replacing a failed starter solenoid or relay in marine engines, lawn tractors, or industrial equipment
• Ideal for auxiliary lighting or winch control circuits requiring an isolated high-current switch
• Suitable for automotive or agricultural applications needing a reliable latching or momentary relay

Specs At A Glance

Good To Know

Q: Will this relay work for both starting and continuous duty applications? A: Yes, as a 12V relay it can handle both intermittent starting loads and continuous loads like lights or fans, but always check the current draw against the relay's rating.

Q: How do I wire this 5-terminal relay? A: Standard pinouts apply: connect the control signal to terminals 85 and 86, and route your high-current circuit through terminals 30 and 87 (or 87a for normally-closed), but verify with your specific application diagram.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
