Ametek SBD-4201-G – 12 Volt Solenoid with Silver contacts


Ametek SBD-4201-G (15-386) Silver contact solenoid.
12 Volt, high amperage continuous duty relay.


SKU: SBD-4201-G Categories: ,


This is the genuine Ametek SBD-4201-G with silver contacts and silver disc.

This solenoid is rated at a full 200 amps continuous on the N.O. (diversion) contacts with a 900 AMP MAKE (engage) and 300 AMP break (disengage) rating.

We have tested this solenoid at more than 440 AMPS of diversion (using approximately a 40-50% duty cycle) with no issues. (Please click here to see our testing results.)

The N.C. contacts are rated at 150 amps continuous, with a 400 amp make and 150 break. (See chart below)

This is TWICE the rated capacity of the copper versions by this manufacture and other vendors compatible copper based products.

Don’t be fooled by lower priced copper based models, they handle half the current and can wear out quickly!
