Relay BLOW 0182# (Finder) F40.52.8 8 A 230 V – electromagnetic control relay

The BLOW 0182# (Finder F40.52.8) electromagnetic control relay is a compact switching device designed for control and switching circuits requiring an 8 A contact rating and a 230 V AC coil. Intended for use in automation, HVAC, lighting and small motor control, this relay provides a reliable mechanical changeover contact in a package compatible with standard relay sockets and DIN-style installations where a small footprint and straightforward wiring are needed.

Advantages

The relay offers a clear separation between coil and contact circuits, ensuring safe control of loads up to 8 A. Its compact form factor supports space-saving panel designs and simple replacement in systems using compatible socket mounts. The electromechanical design provides predictable on/off behavior, good electrical isolation, and straightforward maintenance compared with solid-state alternatives.

Suitable for

• Control circuits in building automation and HVAC systems
• Lighting switching and control panels
• Switching small single-phase motors and pumps within the rated current
• Relay socket installations and DIN-panel assemblies requiring compact control relays

Key specifications

• Coil nominal voltage: 230 V AC
• Contact rating: 8 A (suitable for resistive and moderate inductive loads within manufacturer limits)
• Contact type: changeover (mechanical switching contacts)
• Mounting compatibility: standard relay socket and DIN-style panel configurations
• Application class: electromagnetic control relay for switching and control tasks

How to use

Install the relay into a compatible socket or DIN-panel holder according to the system layout and wiring diagram. Make sure supply power is disconnected during installation. Connect the coil to a 230 V AC control circuit and wire the common, normally open and normally closed terminals to the load and control devices as required. After installation, restore power and verify correct switching by energizing the coil and checking contact operation under no-load and then with the intended load, observing safety precautions and electrical standards.

Usage recommendations

Use the relay within its rated coil voltage and contact current limits; avoid exceeding 8 A continuous current. Employ proper surge suppression or snubbers when switching inductive loads, and follow local electrical codes for wiring, protection and earthing. Periodically inspect contacts and socket connections for wear or corrosion when used in frequent switching or harsh environments.
