Frequently Asked Questions

Q: What is the difference between the KTO011 (Normally Open) and KTS011 (Normally Closed) thermostat models?

A: The KTO011 is a Normally Open (NO) thermostat — the circuit remains open (off) at ambient temperature and closes (activates) when the set temperature is reached. The KTS011 is a Normally Closed (NC) thermostat — the circuit is closed (on) at ambient temperature and opens (deactivates) when the set temperature is reached. Choose NO for activating cooling fans or alarms at high temperatures, and NC for activating heaters that should run until a target temperature is met.

Q: How do I mount this mini thermostat in my electrical cabinet?

A: This thermostat features a standard 35mm DIN rail clip (EN60715 compatible) with 4-foot holders. Simply clip it onto your DIN rail inside the cabinet — no additional tools or hardware required. For wiring, use the 2-pole terminal at the bottom, supporting rigid wire up to 2.5 mm² or stranded wire (with ferrule) up to 1.5 mm², and tighten to a maximum clamping torque of 0.5 Nm.

Q: What temperature range can this mechanical thermostat control?

A: The KTO011/KTS011/ZRO011 cabinet thermostat has an adjustable control range of 0°C to 60°C (32°F to 140°F), with a switch temperature differential of 7K (±4K tolerance). The unit itself can be safely stored and operated in environments ranging from -45°C to +80°C (-49°F to +176°F).

Q: Is this thermostat certified for safety and what is its protection rating?

A: Yes, this thermostat is CE certified and features an IP20 protection rating. Its casing is made from UL94 V-0 rated flame-retardant plastic, ensuring it meets international safety standards for electrical enclosure use.
