The KTO 111 is a normally closed mechanical thermostat with a snap-action contact, designed for temperature control in heating applications. It features push-in terminals for tool-free, secure wiring of rigid wires up to 2.5 mm² or stranded wires up to 1.5 mm² with ferrules. The device mounts on a 35 mm DIN rail and measures 2.4 in height, 1.3 in width, and 1.6 in depth. It operates at temperatures from -49 °F to 176 °F, supports switching up to 10 A at 250 VAC and 15 A at 120 VAC for resistive loads, and is rated for 30 W DC switching up to 72 V. The switching differential is 7 K with a tolerance of ±4 K, and service life exceeds 100,000 cycles. The unit meets IP20 protection, UL94 V-0 material standards, and CCC/CQC certifications.
The mechanical thermostats KTO 111 and KTS 111 are two state regulators for use up to 5,000 meters in altitude, thanks to optimized air gap and increased creepage distance. By use of Push-In terminals the thermostat is wired tool-free. The Push-In terminals provide constant pressure on the wires to prevent them from coming loose (e.g. during transport).
Thermostat (NC): Thermostat opens on temperature rise – for regulating heaters or for switching signal devices. Comes with red temperature dial.
Thermostat (NO): Thermostat closes on temperature rise – for regulating filter fans and heat exchangers or for switching signal devices. Comes with blue temperature dial.
