Bosch Normal Open Micro Relay 4‑Pin 12V 30A – Silver Alloy Contacts

Description

Product Overview

The Bosch 0332011007 Normal Open Micro Relay combines a miniature footprint with industrial‑grade performance. Engineered with a 4‑pin layout, the relay measures just 0.53 x 0.56 x 0.93 inches and weighs only 0.705 ounces, making it ideal for space‑constrained designs. Its 12 V coil energizes quickly, while the silver‑alloy contacts provide a low‑resistance path for up to 30 A of current. With a maximum switching power of 360 W and a rating of 250,000 cycles, this component delivers dependable operation in both continuous and intermittent duty cycles. The relay’s exterior is machined for durability, and it meets Bosch’s stringent quality standards, ensuring consistent performance across a wide temperature range from –40 °F to +212 °F.

Usage

Designed for versatility, the Bosch Normal Open Micro Relay is suited for a variety of applications. In industrial control panels, it can manage motor starters, solenoid valves, and lighting circuits where precise, reliable switching is essential. Automotive engineers rely on this relay for functions such as fuel pump control, HVAC system regulation, and auxiliary power distribution, benefiting from its compact size and high current capability. The relay also performs well in marine and aerospace environments, where resistance to vibration and temperature extremes is critical. Its normally open configuration ensures that circuits remain off until the coil is energized, providing safety and energy‑saving benefits in automated systems.

FAQ

What does “normally open” mean for this relay?

A normally open (NO) relay has its contacts open when the coil is not energized. The circuit remains off until voltage is applied to the coil, at which point the contacts close and allow current to flow.

Can this relay be used in automotive applications?

Yes, the relay’s 12 V coil, 30 A contact rating, and compact size make it well‑suited for automotive uses such as controlling fuel pumps, lights, and auxiliary devices.

What temperature range can the relay operate within?

The relay is engineered to function reliably from –40 °F (‑40 °C) up to +212 °F (+100 °C), covering most industrial, automotive, and marine environments.

How many switching cycles can be expected from this relay?

Bosch rates this micro relay for up to 250,000 mechanical switching cycles, providing a long service life for repetitive applications.

Is there a warranty or support available for this product?

Bosch offers a standard warranty and access to technical support resources, ensuring assistance with installation, troubleshooting, and replacement if needed.
