Siemens Sivacon NC, NO Enclosure Thermostat, 250V, 80 °C, -45 °C

This enclosure thermostat is a mechanical temperature control device intended for monitoring and switching temperatures within electrical cabinets and industrial enclosures. It uses a thermal bimetal sensor with snap-action contacts configured as both normally closed and normally open to provide switching for heating or cooling circuits. The unit clips to a 35 mm DIN rail and is suited to alternating current systems up to 250 V.

• Mechanical bimetal sensor provides temperature-dependent switching
• NC and NO contacts allow both heating and cooling control
• Snap-action contact design ensures Rapid state change and reduced arcing
• Typical mechanical life of 100,000 operating cycles supports long service intervals
• Withstands ambient operation from −45 °C to 80 °C for wide deployment

• Suitable for controlling cabinet heaters in electrical enclosures
• Ideal for preventing condensation in relay and control panels
• Used with fan circuits to regulate enclosure internal temperature
• Can be used for Basic temperature interlock functions in switchgear
• Suitable for industrial cabinet thermostat mechanical control loops

It offers a 4-pole Terminal for solid conductor up to 2.5 mm2 and stranded conductor with end sleeve up to 1.5 mm2.

The unit secures by a clip-on mounting to a 35 mm DIN rail and accepts any mounting position.

The housing affords IP20 protection and is constructed from plastic material.

Typical inrush current capability is 10 A on AC supply systems.
