Main alarm switch Elektromet WG-2s 2Z 12A IP55 (model 921441)

Electromet WG-2s is a main alarm switch designed for control and emergency shutdown applications. The device features two changeover contacts (2Z) configurable as normally closed and normally open, and is rated for switching currents up to 12 A. Housed in an IP55 enclosure, the WG-2s provides protection against dust and low-pressure water jets, making it suitable for industrial and commercial installations where a robust manual alarm or isolator switch is required.

Advantages

The WG-2s combines a compact mechanical design with two reliable contact sets that accommodate both NC and NO wiring schemes, enabling versatile integration into control circuits and safety systems. Its 12 A switching capacity covers a wide range of control loads, and the IP55-rated enclosure ensures consistent performance in environments with dust and occasional water exposure. The switch is intended for manual operation and offers straightforward mounting and wiring for maintenance and replacement tasks.

Suitable for

• Manual alarm activation and emergency shutdown in industrial facilities
• Control panels and machine isolator functions
• Commercial building safety systems and service areas
• Environments requiring dust protection and limited water resistance

Key specifications

• Contact configuration: two changeover contacts (2Z) supporting normally closed and normally open connections
• Rated current: 12 A for switching typical control and signaling circuits
• Enclosure protection: IP55, resistant to dust ingress and water jets from any direction
• Operation: manual actuator suitable for direct human operation
• Mounting: panel or surface mounting compatible with standard installation practices

How to use

Install the Electromet WG-2s switch in a location that is easily accessible for manual operation and compliant with local electrical installation standards. Connect the supply and load conductors to the appropriate NC or NO terminals according to the required control logic, and secure the enclosure to prevent moisture ingress beyond the IP55 rating. Verify correct wiring and perform functional testing by operating the switch and observing the controlled equipment or signaling circuit. Ensure the installation is de-energized during wiring and maintenance.

Usage recommendations

Use the WG-2s for signal-level and control circuits up to 12 A; for higher currents or inductive loads, include appropriate contact protection such as RC snubbers or separate contactors. Regularly inspect the enclosure seals and terminal connections in dusty or wet environments to maintain reliability and the rated IP55 protection.
