Product catalog summary

Bistable Switches Overview
Bistable switches are energy-efficient devices with two stable states, used for switching electric loads. They maintain their position without power consumption in the switch-on state, contributing to reduced greenhouse gas emissions.

Specifications
- Available in versions up to 32 A and 80 A.
- Control voltages range from 8 V to 240 V.
- Compliant with IEC/EN 60669-2-2 standards.

Applications
- Suitable for lights, electric heating, electric drives, and intelligent installations.
- Can be controlled via impulse and manual methods.
- Designed for 35 mm rail mounting with sealing terminal covers.

Advanced Features
- Remote switching capabilities.
- No hold coil consumption.
- Selector switch for maintenance disconnection of remote control.

Extended Communication Options
- Communication capabilities (CAN, Modbus, I/O, M-bus) for smart buildings and industry solutions.
- Compatible with ISO 11898 CAN and Modbus-RTU standards.

Accessories
- Sealing covers for switches up to 32 A and 80 A.
- Auxiliary switches and devices for centralized and group control.
- Compensation capacitors and busbars for enhanced functionality.

Technical Characteristics
- Rated operational voltage: 230 V.
- Rated frequency: 50 Hz.
- Emphasizes mechanical endurance and contact reliability.
- Provides power dissipation and thermal current specifications.

Ordering Information
- Detailed ordering numbers, weights, and packaging details are available for each switch type and accessory.

Catalog excerpts

Bistable switches Bistable switches Bistable switches are switching devices with two stable states for switching of all kind of electric loads. When the switch is not initiated electrically or actuated manually, remains stable in its operating position and will change its operating position on initiation or actuation.
