Siemens Contactor, 16A Current Rating, 400V AC Voltage Rating - SIRIUS Innovation Series - 3RT2018-1BB42
Use this 3-pole contactor from Siemens to switch your electrical circuits on and off. Unlike a standard relay, it's suitable for applications with very high current capacities. Rapid opening and closing of contacts within the unit effectively suppresses arcing and interrupts high currents to prevent damage to your machinery. It carries an IP20 (ingress protection) rating, which means the internal components are touch-proof to protect the wires and contacts and prevent electric shocks. By rotating the unit through approximately 180° when mounting it, you can tilt the front to suit your setup. It's a versatile option for use with applications including motors and lighting systems.
• Snap-on and DIN-rail mounting capabilities for space-saving and simple installation
• Compact design of 57.5mm (length), 45mm (width) and 73mm (depth) makes for easy installation in confined spaces
• Wide operating temperature range from -25°C to +60°C for use in tough conditions

Can I install this contactor in outdoor equipment?
Yes, you can use this Siemens contactor outdoors. The housing is made from rugged plastic that withstands damage from corrosion, abrasion and moisture, making the unit weatherproof.
