62.33.9.024.4360 Finder Power relay 3 pole 16A DC 24V

Why Choose the Finder 62.33.9.024.4360 Power Relay?

The Finder 62.33.9.024.4360 is a robust 16 A three-pole electromechanical power relay designed for dependable switching in industrial automation, machinery control and electrical control panels. Part of the established Finder 62 Series, this model features a 24 V DC operating coil, three normally open contacts (3 NO / 3PST-NO), an integrated LED indicator and a built-in flyback diode.

A defining characteristic of the 62.33.9.024.4360 is its three normally open contacts with a contact gap of at least 3 mm. Unlike three-pole changeover relays, which provide both normally open and normally closed connections, this version is designed to close three separate circuits when its coil is energised. The larger contact gap provides increased physical separation between open contacts, making this configuration suitable for industrial applications requiring enhanced contact separation.

The relay also incorporates an LED coil indicator and an integrated suppression diode. The LED provides convenient visual confirmation of coil energisation, while the diode helps suppress the inductive voltage transient generated when the DC coil is switched off. Combined with silver tin oxide (AgSnO2) contacts, Faston 187 quick-connect terminals and a plug-in construction, the Finder 62.33.9.024.4360 is a practical choice for industrial panel builders, automation engineers and maintenance professionals.

Reliable Three-Pole Normally Open Switching with a 3 mm Contact Gap

The Finder 62.33.9.024.4360 uses an electromagnetic mechanism to control three independent normally open contact sets. When the 24 V DC coil is energised with the correct polarity, the internal armature moves and closes all three contact circuits. When the coil supply is removed, the contacts return to their normally open positions.

The 3PST-NO contact configuration is particularly useful where an application requires three circuits to be energised together without the normally closed connections associated with a changeover relay. The minimum 3 mm contact gap distinguishes this model from standard changeover versions of the Finder 62.33 family. However, a larger contact gap alone does not establish suitability as a safety isolator; any isolation or safety-related application must be assessed against the relevant equipment standards and manufacturer's approvals.

Integrated LED Indication and DC Coil Suppression

The integrated LED indicator provides visual confirmation that the relay coil is energised. This feature helps technicians identify active control signals during installation, commissioning and troubleshooting. The LED indicates the electrical status of the coil rather than independently confirming the condition of each switching contact.

The built-in flyback diode helps limit the voltage transient generated when the relay's electromagnetic coil is switched off. This is beneficial when the relay is driven by a compatible PLC output, transistor driver or electronic controller. Because the diode provides a discharge path for the coil current, it may also increase the contact release time compared with an unsuppressed relay.

Correct polarity is essential. The relay's positive and negative coil terminals must be connected according to the manufacturer's terminal markings. Reversing the DC supply can forward-bias the suppression diode and cause excessive current flow. The relay's 125 mA nominal coil current should also be checked against the switching capability of the control output.

Finder 62.33.9.024.4360 vs 62.33.9.024.4060

Although both models use a 24 V DC coil and include an LED indicator and flyback diode, their contact configurations are different.

• Finder 62.33.9.024.4360: Three normally open contacts (3PST-NO), minimum 3 mm contact gap, 3 W coil consumption and 125 mA nominal coil current.
• Finder 62.33.9.024.4060: Three changeover contacts (3PDT), standard changeover contact arrangement and lower nominal coil consumption.

The two relays should not be treated as direct electrical equivalents. Their contact arrangements, terminal functions and coil requirements differ. Before replacing one model with another, verify the complete part number, wiring diagram, coil supply capacity and compatible socket.
