Why Choose the Finder 62.33.8.120.4030 Power Relay?
The Finder 62.33.8.120.4030 is a high-performance 16 A three-pole electromechanical power relay designed for reliable electrical switching in industrial automation, machinery control and electrical control panels. Part of the established Finder 62 Series, this relay features a 120 V AC operating coil, three changeover contacts (3 CO / 3PDT) and an integrated LED indicator, making it a practical solution for industrial control applications requiring dependable switching and visual coil status indication.
With its three independent changeover contacts, the Finder 62.33.8.120.4030 allows three separate electrical circuits to be switched simultaneously using a single control signal. Each contact set provides common, normally open and normally closed connections, offering flexibility for electrical interlocking, auxiliary power switching, signalling and multi-circuit control. The relay's silver tin oxide (AgSnO2) contact material offers good resistance to contact welding and supports reliable operation with appropriately rated electrical loads.
A distinguishing feature of the 62.33.8.120.4030 is its integrated LED coil indicator, which provides convenient visual confirmation when the relay is energised. This can simplify commissioning, inspection and fault-finding in industrial control panels. Combined with Faston 187 quick-connect terminals, compatibility with suitable Finder 92 Series sockets and reinforced insulation between the coil and contacts, the relay provides a versatile switching solution for electrical engineers, automation specialists and maintenance professionals.

Reliable 120 V AC Switching with Integrated LED Indication
The Finder 62.33.8.120.4030 operates through an electromagnetic switching mechanism. When the 120 V AC coil is energised, the relay's internal armature transfers all three changeover contacts from their normally closed positions to their normally open positions. This allows a single AC control signal to operate three independent electrical circuits. When the coil supply is removed, the contacts return automatically to their normal positions, providing conventional monostable operation.
The integrated LED indicator makes this relay particularly useful in industrial control panels where technicians need to identify energised control circuits quickly. The indicator provides visual confirmation of the coil supply, helping with commissioning, maintenance and fault-finding. Unlike versions equipped with a manual test button, the 4030 configuration is intended for normal electrically controlled operation without manual contact actuation. Its Faston 187 terminals and compatibility with suitable Finder 92 Series sockets support convenient wiring and replacement in industrial installations.

Frequently Asked Questions
What is the Finder 62.33.8.120.4030 used for?
The Finder 62.33.8.120.4030 is a three-pole electromechanical power relay used for switching electrical circuits in industrial automation, machinery control and electrical panels. Its three changeover contacts allow three independent circuits to be controlled simultaneously, while the integrated LED provides visual indication of coil energisation.
What coil voltage does the Finder 62.33.8.120.4030 require?
The relay requires a 120 V AC nominal coil supply operating at 50/60 Hz. Its nominal AC coil consumption is approximately 2.2 VA, and the standard operating voltage range is 96–132 V AC. It should not be connected directly to a 120 V DC supply.
What is the contact configuration and current rating of the Finder 62.33.8.120.4030?
The relay features three changeover contacts (3 CO / 3PDT) with a 16 A rated contact current, a 250 V AC rated contact voltage and a 4,000 VA resistive switching capacity (AC1). The permissible load depends on the switching voltage, load characteristics and operating conditions.
Does the Finder 62.33.8.120.4030 include an LED indicator or manual test button?
The Finder 62.33.8.120.4030 includes an integrated LED indicator that provides visual confirmation when the relay coil is energised. The 4030 configuration does not include a lockable manual test button. Other Finder 62 Series versions are available with manual testing and additional indication features.
What is the difference between Finder 62.33.8.120.4030 and 62.33.8.120.4000?
Both models feature a 120 V AC coil and three 16 A changeover contacts. The key difference is that the 62.33.8.120.4030 includes an integrated LED indicator, while the 62.33.8.120.4000 is the standard configuration without an LED. The 4030 version is therefore particularly useful where visual coil status indication is required.
