Siemens 3RF2 Series Solid State Contactor, 70A Operational current, 48 to 460V ac Operating voltage - 3RF2370-3AA04

This solid state contactor is a single-pole electronic switch designed for industrial AC load switching with zero-cross operation. It accepts AC control voltages from 48 to 460V and handles resistive and switching loads up to 70A under rated conditions. The unit is intended for panel or DIN-rail installation and is suitable for environments requiring Compact power switching across a wide ambient temperature range.

Features and Benefits:

• 70A operational current provides high continuous load handling
• Zero-cross switching minimises inrush and electrical noise
• 48 to 460V AC control range supports high-voltage control applications
• 15 to 24V DC control input enables low-voltage signalling compatibility
• Snap-on and screw mounting allows fast installation flexibility

Applications

• Used for resistive heater control in process systems
• Suitable for motor soft-start switching in conveyor lines
• Ideal for load switching in industrial ovens and furnaces
• Can be used in power distribution panels for phase switching

What control supply voltages does it accept?

The control input accepts DC control at 15 to 24V for switching and the device operates on AC control voltages from 48 to 460V at 50 to 60Hz.

How does the device perform thermally under load?

Power loss at rated current is approximately 83W in the hot operating state and the device includes a derating point at 40°C.

What connection methods are provided for the main circuit?

Main current connections use ring cable lug terminals with M5 connection screws and require a 10mm stripped length.

What protection and environmental limits apply during operation?

The unit is rated to IP00, is qualified for -25°C to +60°C operation, and is suitable for installations up to 1000 m altitude.
