Siemens 3RF2 Series Solid State Relay, 40 A Load, Panel Mount, 600 V Load, 30 V dc Control

Use this solid state relay from Siemens to quickly and reliably control the electrical load to your circuit. When the control terminals receive a voltage, a diode emits a light that energises an optocoupler, closing the contacts and allowing the full current to flow through the circuit. This relay has compact dimensions of just 95 (H) x 119.5 (W) x 130mm (D), so it's a good choice for installation in applications where space is at a premium. As it has no moving parts, there's no risk of mechanical wear, so you can be sure of the unit's long service life in applications such as motors, pumps and compressors.

• Screw terminals for a secure electrical connection, even with vibration
• 'On' delay of just 1ms for fast switching
• Wide operating voltage range between 48 and 600V AC for compatibility with low-voltage and medium-voltage applications
• IP20 rating means it's finger-safe and protected against objects larger than 12mm

This SSR has a wide operating temperature range between -25°C and +60°C, so it's suitable for use in harsh industrial environments.
