Finder 22.22.8.048.4000 – 22 Series Modular monostable relays

Why Choose the Finder 22.22.8.048.4000 Modular Contactor?

The Finder 22.22.8.048.4000 is a compact 20 A, two-pole modular contactor featuring a 48 V AC operating coil and two normally open power contacts. Part of the Finder Series 22, this DIN rail-mounted contactor is designed for electrical load switching in lighting installations, building automation systems, distribution boards and industrial control panels.

Featuring a 2 NO (DPST-NO) contact arrangement, the Finder 22.22.8.048.4000 enables two circuits or conductors to be switched simultaneously using a 48 V AC control signal. Its AgSnO2 silver tin oxide contact material provides suitable switching characteristics for demanding electrical applications, including appropriately rated lighting loads with elevated inrush currents.

The contactor's 17.5 mm modular width, standard 35 mm DIN rail mounting and screw terminal connections make it a practical choice for installations where panel space, wiring accessibility and reliable electromagnetic switching are important. Its non-latching operating mechanism provides straightforward control through compatible switches, timers, relays and automation equipment.

Reliable Two-Pole Switching with a 48 V AC Control Coil

The Finder 22.22.8.048.4000 operates using an electromagnetic coil rated at 48 V AC. When the appropriate control voltage is applied, the contactor closes its two normally open contacts, allowing current to flow through the connected load circuits. When the coil is de-energised, the contacts return to their normally open state.

This non-latching operating principle is suitable for applications in which the connected electrical load must follow the state of a control signal. The contactor can be operated through appropriately rated switches, control relays, time switches or building automation controllers with a compatible 48 V AC output.

The 2 NO contact arrangement provides simultaneous switching of two circuits or conductors. With a rated contact current of 20 A, the contactor can be used for appropriately selected lighting and power-control applications. Actual permissible loading depends on the switching category, load power factor, inrush current and the manufacturer's application-specific ratings.

The use of AgSnO2 silver tin oxide contact material makes this contactor suitable for applications requiring robust switching performance. This is particularly relevant in lighting installations, where electronic drivers and other loads may draw substantially higher current during energisation than during normal operation.

Its 17.5 mm modular housing allows installation in compact electrical distribution boards. Standard DIN rail mounting and screw terminals simplify integration into professional electrical panels, while the separation between the operating coil and power contacts allows the control circuit to operate at a different voltage from the switched load.

The 48 V AC coil rating is an essential selection characteristic. This model should not be confused with otherwise similar Finder Series 22 contactors using 12 V, 24 V, 110 V or 230 V operating coils. The correct coil supply, circuit protection and load compatibility must be confirmed before installation.
