Hella 933332571 Micro 280 Automotive Relay 12V 35A 4-Pin SPST with Resistor

The Hella 933332571 is a Micro ISO 280 style automotive relay designed for reliable switching of high-current electrical circuits in automotive applications. This compact 4-pole relay features SPST (Single Pole Single Throw) normally open contacts and integrated resistor coil suppression to minimize electromagnetic interference in sensitive vehicle electrical systems.

Key Features:

• 12-volt nominal operating voltage for compatibility with standard automotive electrical systems
• 35-amp continuous current rating for switching high-power loads
• 4-pin terminal configuration with 2.8mm blade terminals for secure connections
• Resistor coil suppression to protect sensitive electronics from voltage spikes
• Dust cover protection for enhanced reliability in demanding environments
• Compact Micro ISO 280 footprint for space-constrained installations
• Normally open contact design for fail-safe operation

This relay is commonly used for engine control units, accessory power systems, starter circuits, cooling fans, lighting systems, and other critical automotive electrical functions. The integrated resistor provides essential suppression to prevent electromagnetic interference that could affect nearby sensors and control modules. Built to Hella's exacting standards, this relay delivers consistent performance across extreme temperature ranges and harsh operating conditions typical of automotive environments.
