Switch disconnect 2-0-1 3-pole 25A in IP44 enclosure Elektromet Łuk 25-73 (922573)

Electromet Łuk 25-73 (922573) is a 3-pole cam switch disconnect rated for 25 A, delivered in an IP44 enclosure. The switch provides a 2-0-1 configuration (ON‑OFF‑ON) for manual selection of two active positions with a central off, enabling safe isolation and straightforward changeover in three-phase circuits. The IP44 enclosure offers protection against splashing water and access to hazardous parts, making the unit suitable for electrical distribution and control panels in environments where occasional moisture or dust ingress may occur.

Advantages

The cam switch integrates manual changeover and disconnect functionality in a single compact unit, reducing panel wiring complexity. Its 3-pole design ensures simultaneous switching of all phases for safe isolation. The IP44-rated housing provides a balance between protection and accessibility, allowing use in indoor and covered outdoor locations without exposure to heavy water jets. The mechanical cam mechanism gives clear tactile feedback and positive position detents, supporting reliable operation and easy verification of switch position.

Suitable for

• Manual motor direction change or source selection in three-phase motor control
• Service isolation and maintenance disconnection in distribution boards
• Changeover between two power sources or circuits
• Industrial and commercial electrical panels with splash protection requirements

Key specifications

• Number of poles: 3-pole switching for simultaneous phase control
• Switch configuration: 2-0-1 (ON‑OFF‑ON) cam switch
• Rated current: 25 A continuous
• Enclosure protection: IP44 (protection against solid objects >1 mm and splashing water)
• Actuation: manual rotary cam mechanism with defined detents for position feedback
• Mounting: panel or surface mounting suitable for electrical enclosures
• Typical applications: three-phase circuits, motor control, and service isolation

How to use

Install the switch into an appropriate electrical panel or enclosure following local wiring regulations and ensure correct tightening of terminals to the manufacturer's torque recommendations. Connect the three-phase conductors to the input terminals and the load conductors to the corresponding output terminals, verifying phase sequence if required for motor applications. Use the rotary actuator to select the desired position: one extreme for the first active source, the central position for off/isolation, and the opposite extreme for the second active source. Always de-energize the circuit and confirm the absence of voltage before performing wiring or maintenance.

Usage recommendations

For reliable long-term operation, ensure the switch is used within its rated current and environmental limits, avoid exposure to direct water jets, and perform periodic inspection of terminal tightness and contact wear. When used for motor control or frequent changeover, consider the duty cycle and consult a qualified electrician to confirm suitability for switching under load.
