Relay BLOW 3416# (Finder F4.052.9.012) 8 A 12 V electromagnetic miniature

Electromagnetic control relay BLOW 3416# (Finder F4.052.9.012) is a compact miniature relay with a 12 V DC coil designed for switching low-power electrical circuits. With an 8 A switching capacity, this relay is intended for use in control panels, automation systems, HVAC equipment and various industrial applications where reliable on/off switching and space-saving installation are required. The relay can be mounted on PCB or in compatible sockets and offers standard single-contact switching behaviour suitable for simple control tasks.

Advantages

The relay combines a small footprint with a robust switching rating of 8 A, allowing use in confined assemblies while handling typical control loads. A 12 V coil voltage ensures compatibility with common low-voltage control circuits. Its miniature design facilitates PCB or socket mounting and integration into modular control panels. The relay’s straightforward single-contact operation simplifies wiring and replacement in service or maintenance scenarios.

Suitable for

• Control panels and terminal boxes for industrial machines
• Automation and PLC peripheral switching
• HVAC control circuits and thermostatic controls
• Signal switching and low-power load control on PCBs
• Retrofit or replacement in existing socket-mounted relay banks

Key specifications

• Coil voltage: 12 V DC
• Switching capacity: 8 A (suitable for low-power circuits)
• Relay type: electromagnetic miniature relay
• Mounting: PCB or compatible socket mounting
• Contact configuration: single-contact on/off switching (SPST/SPDT depending on base)

How to use

Install the relay on a matching PCB footprint or in a compatible socket according to the device manufacturer’s mounting instructions. Connect the 12 V DC control supply to the coil terminals and wire the load through the relay contact terminals, observing polarity and correct terminal assignment. Verify that the connected load current does not exceed the 8 A switching capacity and ensure adequate wiring and protective devices (fuses, circuit breakers) are in place. Perform a functional test after installation to confirm reliable switching.

Usage recommendations

Use the relay within its rated coil voltage and switching current limits, avoid prolonged operation at maximum load, and employ appropriate surge or flyback suppression on the coil when driving from electronic circuits. For reliable long-term operation, select sockets and PCB layouts that ensure secure contacts and consider ambient temperature and ventilation when installing in dense control panels.
