CTT-C70 models

  • CTT-C7005N
  • CTT-C7020N
  • CTT-C7055B

Available models and sizes as currently listed in the B2B shop. Non-standard versions are made to order.

In brief

  • Two contact variants: C-1 rated 15 (3) A and C-2 rated 2.5 (0.6) A, both at 400 VAC.
  • A hysteresis of 3/4 ± 2°C tells you how far the temperature has to move from the setpoint before the contact switches.
  • 1500 mm capillary, connection by a 6.3 × 0.8 mm faston terminal, white or black knob.
  • The housing withstands up to 110°C, so the thermostat can work next to a heat source.

Thermostat with a capillary – various models CTT-C70 – how to choose the right one

CTT-C70 is a thermostat with a 1500 mm capillary, available in two contact ratings: C-1 at 15 (3) A 400 VAC and C-2 at 2.5 (0.6) A 400 VAC. Connection is made with a 6.3 × 0.8 mm faston terminal.

The choice between C-1 and C-2 is a sixfold difference in current on a resistive load and more than fourfold on an inductive one. The stronger version will drive a load directly, the weaker is intended for controlling a coil.

A hysteresis of 3/4 ± 2°C defines the gap between switching on and switching off. The narrower the band, the more frequent the cycles, and with a compressor the number of starts per hour translates directly into its service life.

How to match controls and accessories to a circuit – we explained it in the selection guide for this category.

Where it works

  • Temperature control without an electronic system and its power supply
  • 400 V circuits requiring a 15 A rating – version C-1
  • Controlling a contactor coil with a current of up to 2.5 A – version C-2
  • Appliances in which the thermostat housing sits next to a heat source

Ask a question
What does the notation 15 (3) A mean?

The first figure is the current on a resistive load, the second on an inductive, that is a motor load. A fan and a compressor count according to that second value.

Does the knob change anything besides the colour?

No, the white and the black differ only in appearance. The electrical parameters and the hysteresis remain identical.
