Connection Diagrams

Connection schemes for each relay type are provided, showing coil terminals (A1, A2) and main contact terminals (1, 2, 3, 4). The BR-216-10 model includes a simplified connection with line (L) and neutral (N) terminals.

Load Capacities and Lamp Compatibility

The relays support various lamp types with specified maximum currents per pole:

• Incandescent and halogen lamps: up to 2 A per pole
• Fluorescent lamps with external electromagnetic ballasts (uncorrected and corrected)
• High pressure mercury vapor, metal halide, and sodium vapor lamps with electromagnetic or electronic ballasts
• LED lamps and LED power supplies

Tables provide detailed capacitance (μF) and power factor correction data for different lamp loads and relay types, enabling proper sizing and compatibility checks.

General Features and Benefits

• Bistable relays operate by impulse command, ideal for lighting control in residential, commercial, and industrial buildings.
• They allow multiple push-buttons connected in parallel with two wires, simplifying installation and reducing wiring complexity compared to traditional AC or cross switches.
• Zero power consumption and noiseless operation in steady state due to bistable design.
• Manual control via a switch on the relay panel is available for status indication and manual override.
• Models BR-220 and BR-232 support disconnection of electrical switch control for manual-only operation during maintenance.

Standards and Environmental Conditions

• Compliance with IEC/EN 60669-2-2 standard.
• Mounting on DIN Rail TH35 (IEC/EN 60715).
• Degree of protection: IP20.
• Operating temperature range: -25 to +55 °C (up to +70 °C for short pulses).
• Storage temperature range: -30 to +80 °C.
• Supports side-by-side installation without limitation under 55 °C.

Installation and Maintenance Recommendations

• Use appropriate wire sizes and tightening torques for main and control circuits to ensure reliable connections.
• Ensure maximum back-up fuse ratings are respected to protect against short circuits.
• For lighting loads with capacitive or inductive ballasts, consult provided tables to verify compatibility and avoid relay damage.
• Manual override switches should be used for maintenance or service to safely disconnect control circuits.
