62.33.9.048.0074 Finder Power relay 3 pole 16A DC 48V
Finder 62.33.9.048.0074 is a 16 A three-pole changeover power relay with a 48 V DC coil, lockable test button, mechanical flag indicator, LED and suppression diode.
Why Choose the Finder 62.33.9.048.0074 Power Relay?
The Finder 62.33.9.048.0074 is a robust three-pole electromagnetic power relay designed for dependable switching in industrial control panels, machinery and automation systems. As part of the Finder 62 Series, it combines three changeover contacts with a high switching capacity and a convenient plug-in format.
This relay features a 48 V DC coil and three changeover contacts rated at 16 A. Its lockable test button enables manual operation during commissioning and fault-finding, while the mechanical flag indicator and LED provide clear visual confirmation of the contact position and coil status.
A built-in suppression diode helps protect PLC outputs and other sensitive control electronics from the reverse-voltage transient produced when the coil is switched off. With an AC1 rated load of 4,000 VA, a maximum switching voltage of 400 V AC and plug-in Faston 187 terminals, the 62.33.9.048.0074 is well suited to demanding industrial control duties.

- Integrated lockable test button and mechanical flag indicator.
- Built-in LED and polarity-sensitive suppression diode.
- Plug-in mounting with Faston 187 terminals.
Reliable Switching for Industrial Control Systems
Electromagnetic power relays allow a low-power control signal to operate electrically isolated load circuits. The Finder 62.33.9.048.0074 uses a 48 V DC coil to operate three changeover contacts, enabling one control signal to switch up to three separate circuits between normally closed and normally open states.
The suppression diode absorbs the inductive voltage generated when the DC coil is de-energised, helping protect PLC outputs and electronic control devices. Because the diode makes the coil polarity-sensitive, the positive supply must be connected to terminal A1. The lockable test button, LED and mechanical flag indicator also support efficient commissioning and fault diagnosis.
Typical Applications
- Industrial control panels and automation cabinets.
- PLC-controlled machinery and production equipment.
- Industrial motor-control circuits.
- Burners, boilers, furnaces and heating systems.
- Road and tunnel lighting controls.
- Electrical power-management systems.
